Certified Scrum Trainer (CST) Practice Test — Questions and Answers

Question 1: A CST observes that a Scrum Team's Sprint Reviews always end with no actionable feedback from stakeholders. What is the most likely root cause?

The Sprint Goal was too ambitious, preventing completion
The Increment is not potentially releasable, so stakeholders cannot give meaningful input (Correct answer)
Stakeholders are deliberately withholding feedback to sabotage the team
The Scrum Master is facilitating the review too formally

Correct answer: The Increment is not potentially releasable, so stakeholders cannot give meaningful input

Stakeholders can only give meaningful feedback on a working, potentially releasable Increment; non-functional or incomplete software produces silence.

Question 2: Which LeSS principle emphasizes that teams should be organized around customer-facing features rather than technical components?

Whole Product Focus
Feature Teams over Component Teams (Correct answer)
Systems Thinking
Empirical Process Control

Correct answer: Feature Teams over Component Teams

LeSS strongly favors Feature Teams—cross-functional teams capable of delivering end-to-end customer features—over siloed Component Teams.

Question 3: During a team coaching engagement, the coach identifies that the team's poor retrospective outcomes are caused by tension with a stakeholder outside the team. The systemic approach would be to:

Help the team understand and address the cross-boundary dynamic affecting their system (Correct answer)
Focus retrospectives purely on internal team processes
Advise the team to ignore external pressures during retrospectives
Escalate the stakeholder issue to the Agile Coach

Correct answer: Help the team understand and address the cross-boundary dynamic affecting their system

Systemic team coaching addresses both within-team dynamics and the team's boundary with the broader organization, since external relationships shape internal behavior.

Question 4: Which statement best describes the Product Backlog in the context of empiricism?

It is a sprint-by-sprint delivery schedule
It is an emergent, ordered list that evolves as more is learned (Correct answer)
It is a fixed contract agreed upon at project start
It is a static requirements document maintained by the Scrum Master

Correct answer: It is an emergent, ordered list that evolves as more is learned

The Product Backlog is never complete and evolves as the product, market, and understanding of the work changes.

Question 5: In the context of systemic team coaching, 'psychological safety' is best understood as:

A systemic property of the team that emerges from interaction patterns and is maintained collectively (Correct answer)
The responsibility of HR to enforce through policy
Ensuring team members have ergonomic workstations
An individual team member's personal resilience level

Correct answer: A systemic property of the team that emerges from interaction patterns and is maintained collectively

Psychological safety is a team-level, emergent property shaped by accumulated micro-interactions — it cannot be created by any single person's action but is co-created systemically.

Question 6: During refinement, a Developer discovers that implementing a high-priority feature requires a significant database schema change affecting lower-priority items. The best action is:

Raise this with the Product Owner so the schema change can be ordered and planned appropriately (Correct answer)
Remove the lower-priority items from the backlog
Ignore the dependency since lower-priority items may never be built
Implement the schema change covertly during the next Sprint

Correct answer: Raise this with the Product Owner so the schema change can be ordered and planned appropriately

Hidden technical dependencies must be surfaced to the Product Owner so they can inform ordering and Sprint Planning decisions.

Question 7: A retrospective where the Scrum Master speaks for most of the time and proposes all improvement ideas exemplifies which anti-pattern?

Closed retrospective
Facilitator takeover (Correct answer)
Sprint Review confusion
Retrospective fatigue

Correct answer: Facilitator takeover

Facilitator takeover happens when the Scrum Master dominates rather than facilitating, removing team ownership of the improvement process.

Question 8: During Sprint Planning, the Development Team identifies a dependency on an external vendor that could block the Sprint Goal. What should the team do?

Ask the Scrum Master to remove the dependency before Sprint Planning ends
Push the Sprint Goal to the next Sprint until the dependency is resolved
Raise the dependency as a risk and factor it into the Sprint forecast or select alternative backlog items (Correct answer)
Ignore the dependency and address it if it becomes a problem during the Sprint

Correct answer: Raise the dependency as a risk and factor it into the Sprint forecast or select alternative backlog items

Identified dependencies should be factored into the team's forecast; ignoring them risks Sprint failure and undermines transparency.

Question 9: A Product Owner is unavailable during the Sprint and delegates backlog decisions to a senior developer. This is:

Fine as long as the Scrum Master approves the arrangement
Acceptable if the senior developer has domain knowledge
Recommended for cross-functional team development
Problematic because the Product Owner accountability cannot be delegated (Correct answer)

Correct answer: Problematic because the Product Owner accountability cannot be delegated

While the Product Owner may consult others, they cannot delegate their accountability for the Product Backlog and maximizing product value.

Question 10: Which Scrum Trainer behavior best models the Scrum value of 'Openness' during curriculum delivery?

Acknowledging when a participant raises a valid challenge to the trainer's interpretation (Correct answer)
Allowing participants to skip activities they find uncomfortable
Sharing all proprietary training materials freely with all participants
Posting the full class schedule publicly before the course begins

Correct answer: Acknowledging when a participant raises a valid challenge to the trainer's interpretation

Openness includes being transparent about uncertainty and open to other perspectives, which a trainer models by acknowledging valid challenges.

Question 11: During Sprint Planning, the team is unable to forecast a Sprint Goal because requirements are unclear. As a facilitating CST, the BEST action is:

Recommend shortening the Sprint to reduce risk
Help the team craft a learning-oriented Sprint Goal focused on the uncertainty itself (Correct answer)
Suggest the team pull in the highest-priority backlog items regardless of a goal
Postpone Sprint Planning until the Product Owner clarifies all requirements

Correct answer: Help the team craft a learning-oriented Sprint Goal focused on the uncertainty itself

When requirements are unclear, a learning-oriented Sprint Goal ('we will know X by end of Sprint') aligns with empiricism and allows the team to move forward productively.

Question 12: In LeSS Huge, what structure is used to manage large product domains with thousands of people?

Portfolio Epics and Value Streams
Nexus Integration Teams
Program Increments and ARTs
Requirement Areas with Area Product Owners (Correct answer)

Correct answer: Requirement Areas with Area Product Owners

LeSS Huge introduces Requirement Areas—temporary groupings of related requirements—each served by an Area Product Owner to manage scale beyond 8 teams.

Question 13: When should Product Backlog Refinement occur according to the Scrum Guide?

Only after the Sprint Retrospective when the next Sprint is planned
Continuously throughout the Sprint as needed by the team (Correct answer)
Only during Sprint Planning to keep events consolidated
As a formal 5th Scrum event held at the mid-point of each Sprint

Correct answer: Continuously throughout the Sprint as needed by the team

Product Backlog Refinement is an ongoing activity that occurs throughout the Sprint, not a prescribed formal event with a fixed time-box.

Question 14: During a Sprint Review, the Development Team demonstrates a feature and the Product Owner says it is 'Done.' Two days later a critical bug is found. What should happen?

The Scrum Master decides whether to roll back the release
A new Product Backlog Item is created to address the bug in a future Sprint (Correct answer)
The Development Team must fix the bug before the next Sprint Review
The Sprint is retroactively marked as failed

Correct answer: A new Product Backlog Item is created to address the bug in a future Sprint

Bugs discovered after a Sprint are handled as new Product Backlog Items, prioritized by the Product Owner for a future Sprint.

Question 15: Why does the Scrum Guide specify that a Sprint should be no longer than one month?

Because longer Sprints require additional Scrum events
To align with typical business billing cycles
To limit risk and enable frequent inspection and adaptation (Correct answer)
To ensure teams can plan work at least one month in advance

Correct answer: To limit risk and enable frequent inspection and adaptation

Shorter Sprints limit the cost of risk by allowing frequent empirical inspection and adaptation before too much can go wrong.

Question 16: Which retrospective format structures discussion around a timeline of Sprint events and asks team members to add emotional reactions to each event?

SWOT Analysis
Timeline Retrospective (Correct answer)
Lean Coffee
Starfish

Correct answer: Timeline Retrospective

The Timeline Retrospective maps Sprint events chronologically and layers emotional data, helping teams see patterns and turning points over time.

Question 17: What promotes learner engagement during training?

Interactive discussions and real-world applications (Correct answer)
Reading slides verbatim.
Avoiding participant questions.
One-way lectures only.

Correct answer: Interactive discussions and real-world applications

Learner engagement is significantly promoted when training involves interactive discussions, allowing participants to share ideas and ask questions, and when content is connected to real-world applications. These methods make the learning relevant, encourage active participation, and help learners apply new knowledge to practical scenarios.

Question 18: The 'Starfish' retrospective format asks teams to categorize actions into five areas. Which option correctly lists all five?

Like, Dislike, Idea, Concern, Question
What, So What, Now What, Who, When
Stop, Start, Continue, More Of, Less Of (Correct answer)
Keep, Add, Remove, Improve, Experiment

Correct answer: Stop, Start, Continue, More Of, Less Of

The Starfish format uses five arms: Stop, Start, Continue, More Of, and Less Of — giving nuanced gradations beyond a binary keep/drop choice.

Question 19: Which assessment approach is most aligned with adult learning theory when evaluating comprehension during a Scrum training?

Scenario-based discussions where learners apply concepts to real problems (Correct answer)
Memorization drills on the Scrum Guide
Multiple-choice tests administered at the start of each day
Graded written exams with letter scores

Correct answer: Scenario-based discussions where learners apply concepts to real problems

Adult learners are most engaged when they apply concepts to real-world scenarios, which also reveals deeper comprehension.

Question 20: How does the Sprint Review differ from a traditional project milestone review?

Traditional milestone reviews allow more stakeholder participation than Sprint Reviews
Sprint Reviews are iterative inspect-and-adapt events that update the Product Backlog, not one-time approvals (Correct answer)
Sprint Reviews occur only at the end of the project, similar to traditional reviews
Sprint Reviews are less formal and therefore less valuable for stakeholders

Correct answer: Sprint Reviews are iterative inspect-and-adapt events that update the Product Backlog, not one-time approvals

Unlike milestone reviews, Sprint Reviews happen every Sprint and directly feed learning back into the Product Backlog for continuous adaptation.

Question 21: Which retrospective format uses the metaphor of a hot air balloon with sandbags and hot air to distinguish what slows the team from what energizes it?

Speed Car
Weather Report
Sailboat
Hot Air Balloon (Correct answer)

Correct answer: Hot Air Balloon

The Hot Air Balloon retrospective uses 'hot air' for what lifts the team and 'sandbags' for what weighs it down, making impediments and energizers tangible.

Question 22: What is the relationship between Product Backlog refinement and release forecasting?

Refinement replaces the need for a release plan in Scrum
Well-refined backlogs with consistent estimates allow teams to forecast release dates more reliably using velocity (Correct answer)
Release dates must be fixed before refinement can begin
Refinement has no impact on release forecasting

Correct answer: Well-refined backlogs with consistent estimates allow teams to forecast release dates more reliably using velocity

A refined, estimated backlog combined with known team velocity enables probabilistic forecasting of when features may be delivered.

Question 23: What artifact is unique to Nexus that does NOT exist in single-team Scrum?

Product Backlog
Definition of Done
Sprint Goal
Nexus Sprint Backlog (Correct answer)

Correct answer: Nexus Sprint Backlog

The Nexus Sprint Backlog is unique to Nexus and visualizes all the work selected by the teams for the Sprint plus their cross-team dependencies.

Question 24: What is the PRIMARY risk of a CST who gives advice too quickly during a coaching session?

The coachee may receive inaccurate information
The coachee may rely on the CST for all future decisions
It reduces the coachee's ownership and capacity for self-discovery (Correct answer)
The session may run longer than scheduled

Correct answer: It reduces the coachee's ownership and capacity for self-discovery

Premature advice creates dependency and bypasses the self-discovery process that coaching is specifically designed to develop.

Question 25: Which of the following is a fundamental principle of sprint planning & sprint review as it applies to Certified Scrum Trainer?

Prioritizing speed of completion over accuracy and compliance
Relying solely on personal experience without reference to guidelines
Avoiding documentation to streamline workflow efficiency
Systematic evaluation and adherence to established industry standards (Correct answer)

Correct answer: Systematic evaluation and adherence to established industry standards

A fundamental principle of sprint planning & sprint review in Certified Scrum Trainer is the systematic evaluation and adherence to established industry standards, which ensures consistency, quality, and regulatory compliance across all professional activities.

Question 26: A stakeholder insists on attending every refinement session and directing the team on technical implementation. What should the Scrum Master do?

Explain that stakeholders may attend by invitation and should share 'what' and 'why,' not 'how' (Correct answer)
Remove the stakeholder from future sessions without explanation
Allow it because stakeholders should always be included in Scrum ceremonies
Ask the Product Owner to relay stakeholder input through formal documents

Correct answer: Explain that stakeholders may attend by invitation and should share 'what' and 'why,' not 'how'

Stakeholders can provide valuable context in refinement, but directing implementation undermines the Developers' self-management.

Question 27: In systemic team coaching, 'rank' awareness is important because:

Teams need a clear hierarchy to make decisions faster
Unexamined differences in power, privilege, and status create invisible dynamics that distort team communication (Correct answer)
Senior engineers should have more voting rights in technical decisions
The Product Owner's rank must be formally acknowledged by the team

Correct answer: Unexamined differences in power, privilege, and status create invisible dynamics that distort team communication

Rank dynamics — formal and informal — shape who speaks, who is heard, and who remains silent, often invisibly; systemic coaches surface these to create more equitable team participation.

Question 28: According to the Team Diagnostic Survey (TDS), which of the following is NOT one of the essential team coaching conditions?

An enabling structure
A real team with clear boundaries
A compelling direction
A certified ScrumMaster leading retrospectives (Correct answer)

Correct answer: A certified ScrumMaster leading retrospectives

Hackman's conditions for team effectiveness include real team, compelling direction, enabling structure, supportive context, and expert coaching — not a specific role certification.

Question 29: When should a Scrum Master consider using a structured root cause analysis technique like Fishbone (Ishikawa) diagrams in a retrospective?

When a significant recurring problem has persisted across multiple Sprints (Correct answer)
When the team has fewer than five members
When the Product Owner requests a process audit
When the team exceeds its velocity target

Correct answer: When a significant recurring problem has persisted across multiple Sprints

Fishbone diagrams are most valuable for persistent, complex problems where simple brainstorming has failed to surface the true systemic cause.

Question 30: What is an important consideration when evaluating training effectiveness?

Evaluate if learning objectives were achieved (Correct answer)
Focus only on attendance rates.
Avoid collecting participant feedback.
Base evaluation solely on trainer opinion.

Correct answer: Evaluate if learning objectives were achieved

The most important consideration when evaluating training effectiveness is to determine if the stated learning objectives were met by the participants. This assessment directly measures whether the training successfully imparted the intended knowledge, skills, or behaviors, providing concrete evidence of its impact and value.

Question 31: A CST is training a distributed team across three time zones. Which design principle should most strongly influence the virtual course structure?

Design shorter, more frequent sessions with asynchronous components to respect time-zone constraints and reduce fatigue (Correct answer)
Record the live sessions and allow participants to watch asynchronously at their convenience
Schedule all sessions in the time zone where the majority of participants are located
Run all sessions in a single long day to minimize the number of days participants must be available

Correct answer: Design shorter, more frequent sessions with asynchronous components to respect time-zone constraints and reduce fatigue

Distributed teams across multiple time zones benefit most from shorter synchronous sessions blended with async work, balancing inclusion and sustainability.

Question 32: Which of the following is NOT listed as a Scrum Value in the Scrum Guide?

Courage
Respect
Openness
Efficiency (Correct answer)

Correct answer: Efficiency

The five Scrum Values are Commitment, Focus, Openness, Respect, and Courage — efficiency is not among them.

Question 33: How does self-organization relate to accountability in Scrum?

Accountability belongs solely to the Scrum Master
Self-organizing teams have no individual accountability
Only the Product Owner is accountable for outcomes
The entire team is collectively accountable for the Increment's quality and value (Correct answer)

Correct answer: The entire team is collectively accountable for the Increment's quality and value

Self-organization and collective accountability are paired—teams that decide how to work together own the results of those decisions.

Question 34: A team consistently delivers Increments but stakeholders say the quality is poor. What artifact should the CST examine first?

The Product Backlog
The Sprint Goal
The Definition of Done (Correct answer)
The Sprint Backlog

Correct answer: The Definition of Done

If stakeholders perceive quality as poor despite items being 'done,' the DoD likely lacks sufficient quality criteria to match stakeholder expectations.

Question 35: A Product Owner notices that a key stakeholder has stopped attending Sprint Reviews. What is the BEST first step?

Escalate to senior leadership to mandate their participation
Remove them from the invite list since they clearly aren't interested
Have a direct conversation to understand their concerns and re-engage them (Correct answer)
Send a written summary of Sprint Reviews to replace their attendance

Correct answer: Have a direct conversation to understand their concerns and re-engage them

Direct conversation surfaces root causes of disengagement and is the foundation of rebuilding stakeholder trust.

Question 36: During Sprint Planning, the Development Team breaks selected Product Backlog items into tasks. These tasks are best described as:

The Development Team's internal plan for achieving the Sprint Backlog items (Correct answer)
Requirements imposed by the Scrum Master to track daily progress
Commitments made to stakeholders during Sprint Review
New Product Backlog Items that the Product Owner must approve

Correct answer: The Development Team's internal plan for achieving the Sprint Backlog items

Tasks are the Development Team's own decomposition to organize their work; they belong to the team, not to external parties.

Question 37: A Product Owner wants to forecast when a set of 30 backlog items will be complete. The team's recent throughput is 6 items per sprint. What is the MOST appropriate probabilistic approach?

Double the estimate to 10 sprints as a safety buffer
Ask developers to re-estimate all items in hours for precision
Divide 30 by 6 and commit to exactly 5 sprints
Use a Monte Carlo simulation based on historical throughput distribution (Correct answer)

Correct answer: Use a Monte Carlo simulation based on historical throughput distribution

Monte Carlo simulation uses historical throughput variability to generate probabilistic forecasts rather than single-point estimates.

Question 38: A team has high trust internally but consistently conflicts with other teams in the organization. From a systemic perspective, this most likely indicates:

The other teams need coaching, not this one
The team may have strong in-group cohesion that creates an 'us vs. them' dynamic with the broader system (Correct answer)
The team is performing well and should be left alone
The Scrum Master should negotiate inter-team agreements

Correct answer: The team may have strong in-group cohesion that creates an 'us vs. them' dynamic with the broader system

High internal cohesion that produces external conflict is a systemic pattern — the team boundary may be too rigid, limiting healthy interdependency with the organizational system.

Question 39: Which Agile principle is most violated when a manager assigns specific tasks to individual developers?

Welcome changing requirements
Simplicity is essential
Deliver working software frequently
The best architectures emerge from self-organizing teams (Correct answer)

Correct answer: The best architectures emerge from self-organizing teams

Self-organizing teams select and assign their own work; external task assignment violates the principle that teams determine how to best accomplish their goals.

Question 40: What is the primary risk when a Scrum Team generates more than five improvement actions in a single retrospective?

None of the actions get completed due to overcommitment (Correct answer)
The Definition of Done needs to be updated for each action
The Sprint Backlog becomes overloaded with non-feature work
The Product Owner must approve each action item

Correct answer: None of the actions get completed due to overcommitment

Selecting too many improvement actions dilutes focus and effort, resulting in none being completed — a key reason experts recommend limiting actions to one or two per retrospective.

Question 41: A Development Team has been stable for six months and now consistently completes exactly 40 story points per Sprint. During Sprint Planning, they select 55 points. What risk does this create?

The Product Owner will cancel the Sprint for over-commitment
The Scrum Master is obligated to reduce the selection to 40 points
The team is likely to carry over unfinished work, eroding trust and Sprint integrity (Correct answer)
The team will exceed their Definition of Done

Correct answer: The team is likely to carry over unfinished work, eroding trust and Sprint integrity

Selecting far more work than historical velocity supports typically leads to incomplete Sprints, which undermines stakeholder trust and team morale.

Question 42: When documenting activities related to retrospective formats & anti-patterns, which practice is considered essential for CST certification holders?

Completing documentation only when requested by auditors or supervisors
Recording only outcomes while omitting the methods and processes used
Maintaining comprehensive records that include procedures, observations, results, and any anomalies (Correct answer)
Keeping documentation in personal notes that are not accessible to other team members

Correct answer: Maintaining comprehensive records that include procedures, observations, results, and any anomalies

Comprehensive documentation that includes procedures, observations, results, and any anomalies is essential in retrospective formats & anti-patterns. This supports quality assurance, enables peer review, and satisfies regulatory and audit requirements.

Question 43: Which of the following is a fundamental principle of stakeholder collaboration & trust as it applies to Certified Scrum Trainer?

Prioritizing speed of completion over accuracy and compliance
Avoiding documentation to streamline workflow efficiency
Relying solely on personal experience without reference to guidelines
Systematic evaluation and adherence to established industry standards (Correct answer)

Correct answer: Systematic evaluation and adherence to established industry standards

A fundamental principle of stakeholder collaboration & trust in Certified Scrum Trainer is the systematic evaluation and adherence to established industry standards, which ensures consistency, quality, and regulatory compliance across all professional activities.

Question 44: The Sprint Review reveals that the Increment does not meet stakeholders' expectations despite meeting all acceptance criteria. What does this most likely indicate?

Sprint Reviews should be eliminated in favor of more frequent demos
The acceptance criteria did not fully capture stakeholder needs—a Product Backlog refinement gap (Correct answer)
The Development Team should have worked overtime to exceed the criteria
The Scrum Master failed to facilitate the Sprint Review correctly

Correct answer: The acceptance criteria did not fully capture stakeholder needs—a Product Backlog refinement gap

A gap between met criteria and stakeholder satisfaction points to incomplete or misaligned acceptance criteria that should be improved through better refinement.

Question 45: Which activity best assesses whether learners can differentiate between Sprint Review and Sprint Retrospective?

Having learners read the Scrum Guide definitions aloud
Asking learners to list all Scrum events from memory
Giving learners a set of agenda items and asking them to sort each into the correct event, then defend their choices (Correct answer)
Testing learners on the recommended duration of each event

Correct answer: Giving learners a set of agenda items and asking them to sort each into the correct event, then defend their choices

Sorting and justifying items requires learners to apply conceptual distinctions, revealing the depth of their understanding.

Question 46: Which practice helps a self-organizing team maintain alignment with the Sprint Goal when priorities shift mid-Sprint?

Sprint Planning re-runs
Emergency Scrum of Scrums
Daily Scrum (Correct answer)
Escalation to the Product Owner for every change

Correct answer: Daily Scrum

The Daily Scrum is specifically designed to inspect progress toward the Sprint Goal and adapt the plan for the next 24 hours.

Question 47: A 'spike' added to the Product Backlog during refinement is best described as:

A time-boxed research or investigation task to reduce uncertainty (Correct answer)
A placeholder for incomplete user stories
An emergency bug fix that must be addressed immediately
A technical debt item to be resolved in the next Sprint

Correct answer: A time-boxed research or investigation task to reduce uncertainty

A spike is a time-boxed activity used to gain the knowledge needed to estimate or implement a story.

Question 48: The Scrum Guide describes the Scrum Master as a 'true leader who serves the Scrum Team.' This concept is known as:

Servant leadership (Correct answer)
Situational leadership
Transactional leadership
Transformational leadership

Correct answer: Servant leadership

The Scrum Master embodies servant leadership by serving the team's needs, removing impediments, and enabling self-management rather than directing work.

Question 49: Which retrospective format asks each participant to write one word that describes the Sprint before any discussion begins?

Return on Time Invested
ESVP Check-In
One Word Retrospective (Correct answer)
Weather Report

Correct answer: One Word Retrospective

The One Word Retrospective is a lightweight opener that surfaces diverse emotional snapshots quickly before deeper structured discussion.

Question 50: A Scrum Team notices their velocity has been steadily declining for three sprints. What is the MOST appropriate first step?

Add more developers to the team immediately
Inspect the causes during the Sprint Retrospective (Correct answer)
Increase the sprint length to allow more work
Reduce the Definition of Done to complete more items

Correct answer: Inspect the causes during the Sprint Retrospective

The Retrospective is the proper Scrum event to inspect and adapt on process issues like declining velocity.

Question 51: What is the primary ethical obligation of a CST professional when a conflict of interest arises during systemic team coaching activities?

Ignore the conflict if it does not directly affect the current task
Proceed while favoring the outcome that benefits the professional personally
Resolve the conflict privately without informing stakeholders
Disclose the conflict to all relevant parties and recuse from the decision if necessary (Correct answer)

Correct answer: Disclose the conflict to all relevant parties and recuse from the decision if necessary

The primary ethical obligation when a conflict of interest arises in systemic team coaching is to disclose it to all relevant parties and, if necessary, recuse from the decision. This maintains professional integrity and stakeholder trust.

Question 52: A CST is asked to coach a team that was just reorganized by management. The most important systemic question to start with is:

How quickly can the team establish a new Definition of Done?
What is the new team's velocity target?
What has the reorganization disrupted in terms of relationships, history, and informal systems the team relied on? (Correct answer)
Which team member should be the new Scrum Master?

Correct answer: What has the reorganization disrupted in terms of relationships, history, and informal systems the team relied on?

Reorganizations disrupt informal networks, trust, and tacit knowledge — a systemic coach helps the team grieve losses and re-establish the relational infrastructure needed to function.

Question 53: T-shirt sizing (XS, S, M, L, XL) is best used for which estimation scenario?

Technical architecture decisions that require precise effort estimates during Sprint Planning
Assigning specific work items to individual team members based on skill level
Tracking team velocity across multiple Sprints for stakeholder reporting
Initial high-level estimation of many backlog items, especially when details are still uncertain (Correct answer)

Correct answer: Initial high-level estimation of many backlog items, especially when details are still uncertain

T-shirt sizing is a quick, relative estimation technique ideal for early-stage backlog grooming when items lack sufficient detail for precise story point estimates.

Question 54: A CST is facilitating a Sprint Review where stakeholders are giving vague feedback like 'looks good.' To generate actionable input, the BEST technique is:

Ask the Product Owner to prepare a list of questions for stakeholders in advance
Thank stakeholders for their positive feedback and close the review
Ask stakeholders to score the product on a 1–10 scale and share one reason for their score (Correct answer)
Present a comparison to competitor products to provoke more critical thinking

Correct answer: Ask stakeholders to score the product on a 1–10 scale and share one reason for their score

Rating scales combined with a one-reason prompt lower the barrier to honest feedback and surface specific insights that are actionable for the Product Owner.

Question 55: What does the 'I' in the INVEST acronym for well-formed User Stories stand for?

Independent (Correct answer)
Incremental
Important
Integrated

Correct answer: Independent

Independent in INVEST means user stories should be self-contained and avoid dependencies on other stories, enabling flexible scheduling and prioritization.

Question 56: In empirical process control, 'adaptation' refers to:

Changing the Sprint length based on team velocity
Updating the Definition of Done after each Sprint
Adjusting artifacts or processes when inspection reveals unacceptable deviations (Correct answer)
Continuously adding new features to the product

Correct answer: Adjusting artifacts or processes when inspection reveals unacceptable deviations

Adaptation means adjusting the process, material being processed, or the product as soon as possible to minimize further deviation.

Question 57: How often should Scrum Teams inspect and adapt in the Scrum framework?

Only at Sprint boundaries
At the end of the project
Weekly, as part of the Daily Scrum
At every Scrum event throughout the Sprint (Correct answer)

Correct answer: At every Scrum event throughout the Sprint

Inspection and adaptation happen continuously throughout the Sprint at every formal event, not just at Sprint boundaries.

Question 58: What is the primary ethical obligation of a CST professional when a conflict of interest arises during sprint planning & sprint review activities?

Resolve the conflict privately without informing stakeholders
Ignore the conflict if it does not directly affect the current task
Proceed while favoring the outcome that benefits the professional personally
Disclose the conflict to all relevant parties and recuse from the decision if necessary (Correct answer)

Correct answer: Disclose the conflict to all relevant parties and recuse from the decision if necessary

The primary ethical obligation when a conflict of interest arises in sprint planning & sprint review is to disclose it to all relevant parties and, if necessary, recuse from the decision. This maintains professional integrity and stakeholder trust.

Question 59: When a CST teaches Nexus, which foundational prerequisite should they emphasize teams must have BEFORE adopting Nexus?

Teams must use LeSS first
Each team must be proficient in single-team Scrum (Correct answer)
Teams must already practice SAFe
All teams must share a single codebase

Correct answer: Each team must be proficient in single-team Scrum

Nexus assumes each constituent Scrum team already understands and practices Scrum effectively, since Nexus builds directly on single-team Scrum.

Question 60: According to systems thinking, a team that applies a 'quick fix' to a recurring problem without addressing root causes is most at risk of:

Experiencing 'fixes that backfire' — where the intervention creates new or amplified problems over time (Correct answer)
Building team expertise through repeated problem-solving cycles
Improving velocity in the short term and sustaining it long-term
Reducing technical debt gradually through repeated fixes

Correct answer: Experiencing 'fixes that backfire' — where the intervention creates new or amplified problems over time

The 'fixes that backfire' systems archetype describes how symptomatic solutions often suppress the symptom while creating compensating dynamics that worsen the underlying issue.

Question 61: A new Development Team member asks why the Sprint Review is a working session rather than a formal presentation. What is the best explanation?

Scrum forbids slide decks and rehearsed content by definition
The Scrum Master lacks authority to organize formal presentations
Formal presentations require executive approval that Scrum does not provide
A collaborative working session generates richer feedback and shared learning than a one-way demo (Correct answer)

Correct answer: A collaborative working session generates richer feedback and shared learning than a one-way demo

The Sprint Review is designed as a collaborative inspect-and-adapt event where conversation and feedback drive more value than a polished show.

Question 62: When coaching a team on self-organization, a CST should emphasize that the Scrum Master's role is to:

Serve as the team's technical lead on complex engineering decisions
Approve all Sprint Backlog items before work begins
Enable the team to develop its own problem-solving and decision-making capabilities (Correct answer)
Protect the team from all external influences and interruptions

Correct answer: Enable the team to develop its own problem-solving and decision-making capabilities

A servant-leader Scrum Master builds the team's capacity for self-management rather than solving problems for them, reducing long-term dependency.

Question 63: The 'drama triangle' (Karpman) is useful in team coaching because it helps identify:

The correct escalation path for blocked items
The three phases of a Sprint
Dysfunctional relational roles (Persecutor, Rescuer, Victim) that teams can cycle through (Correct answer)
How to structure three-amigos refinement sessions

Correct answer: Dysfunctional relational roles (Persecutor, Rescuer, Victim) that teams can cycle through

The drama triangle describes a systemic pattern of dysfunctional roles that teams unconsciously adopt, creating recurring conflict rather than collaborative problem-solving.

Question 64: Which statement about throughput as a flow metric is MOST accurate?

Throughput is equivalent to story point velocity
Throughput only applies when using Kanban, not Scrum
Throughput counts the number of items completed per unit of time (Correct answer)
Throughput measures the time to complete a single work item

Correct answer: Throughput counts the number of items completed per unit of time

Throughput is a count-based metric: the number of work items completed within a defined time period.

Question 65: A stakeholder group has conflicting priorities for the same product. Who is responsible for resolving this conflict?

The entire Scrum Team in a group negotiation session
The Scrum Master, as servant-leader for the organization
Each stakeholder group independently through separate backlogs
The Product Owner, who holds the single authoritative backlog priority (Correct answer)

Correct answer: The Product Owner, who holds the single authoritative backlog priority

The Product Owner has sole accountability for ordering the Product Backlog and must make final prioritization decisions.

Question 66: Why does Scrum prescribe a maximum team size of 10 people?

Larger teams increase licensing costs for agile tooling
Scrum events cannot be completed in prescribed timeboxes with larger teams
Teams larger than 10 require too much coordination, reducing agility and communication quality (Correct answer)
Larger teams create too many artifacts and documentation overhead

Correct answer: Teams larger than 10 require too much coordination, reducing agility and communication quality

Smaller teams communicate more efficiently and self-organize more effectively; beyond 10, coordination overhead grows faster than capacity.

Question 67: According to the INVEST criteria, what does 'Negotiable' mean for a User Story?

The story's acceptance criteria are open to reinterpretation by developers during the Sprint
The business value of the story can be changed by the development team if needed
The story's scope and details can be discussed and adapted through team collaboration (Correct answer)
The story can be moved between Sprints without notifying the Product Owner

Correct answer: The story's scope and details can be discussed and adapted through team collaboration

Negotiable means a User Story is not a rigid contract; its scope and implementation details are open for collaborative discussion between the team and the Product Owner.

Question 68: Which Scrum pillar ensures that decisions are based on what is known, rather than what is hoped or assumed?

Transparency (Correct answer)
Adaptation
Empiricism
Inspection

Correct answer: Transparency

Transparency ensures that the process and work are visible so that decisions can be based on actual observed reality.

Question 69: Who is ultimately responsible for ensuring the Product Backlog is refined sufficiently so Sprints can be planned?

The Stakeholders
The Product Owner (Correct answer)
The Scrum Master
The Developers

Correct answer: The Product Owner

The Product Owner is accountable for Product Backlog management, including ensuring items are sufficiently refined.

Question 70: In the context of product backlog refinement, what role does continuous professional development play for CST practitioners?

It is required only during the first year of certification
It is optional and only needed for career advancement
It ensures practitioners remain current with evolving standards, technologies, and best practices (Correct answer)
It serves primarily as a networking opportunity with no practical benefit

Correct answer: It ensures practitioners remain current with evolving standards, technologies, and best practices

Continuous professional development is essential in product backlog refinement because it ensures CST practitioners remain current with evolving standards, technologies, and best practices, maintaining competency throughout their careers.

Question 71: Which of the following best describes a well-formed User Story?

A Scrum artifact that replaces the traditional requirements document
A technical task assigned to a specific developer in the Sprint Backlog
A detailed specification document reviewed and approved by the Product Owner
A short, simple description of a feature from the perspective of the person who desires it (Correct answer)

Correct answer: A short, simple description of a feature from the perspective of the person who desires it

A User Story is a short, simple description written from the end user's perspective, capturing what they want and why, to facilitate conversation and collaborative refinement.

Question 72: A Scrum Trainer coaching a newly formed team should pay particular attention to which systemic moment that research shows disproportionately shapes a team's long-term patterns?

The very first team interactions and agreements, as early patterns tend to persist (Correct answer)
The first time the team achieves their sprint goal
The first Sprint Review
The first retrospective after a sprint failure

Correct answer: The very first team interactions and agreements, as early patterns tend to persist

Research by Hackman and others shows that early interactions set precedents — the patterns established in a team's first meetings tend to become self-reinforcing norms.

Question 73: A Product Owner is refining backlog items with only the Scrum Master present. Developers are not included. What problem does this create?

Estimates and technical insight from Developers are missing, reducing refinement quality (Correct answer)
The Scrum Master gains too much power over the backlog
This violates the Scrum rule that refinement must include all stakeholders
The Sprint Goal cannot be set without Developer input in refinement

Correct answer: Estimates and technical insight from Developers are missing, reducing refinement quality

Developers bring technical knowledge essential for realistic estimates and identification of risks during refinement.

Question 74: What is the role of acceptance criteria in a User Story?

To document the business justification for including the story in the Product Backlog
To specify the conditions that must be met for the story to be considered complete (Correct answer)
To define the technical implementation approach the Developers should follow
To determine the story point estimate needed before the story enters a Sprint

Correct answer: To specify the conditions that must be met for the story to be considered complete

Acceptance criteria define the specific conditions under which a User Story is considered done, enabling the team and Product Owner to verify the story delivers the intended value.

Question 75: What distinguishes a 'facilitative trainer' from a 'traditional instructor' in a Scrum training context?

A facilitative trainer allows participants to skip modules they already know
A facilitative trainer focuses only on Advanced Scrum certifications
A facilitative trainer draws knowledge from participants and uses activities that generate insight (Correct answer)
A facilitative trainer delivers all content through lecture to maintain consistency

Correct answer: A facilitative trainer draws knowledge from participants and uses activities that generate insight

Facilitative training is learner-centered and experiential, eliciting insight through activities rather than transferring knowledge through lecture.

Question 76: A CST is teaching a remote class and notices engagement dropping significantly after 45 minutes. What is the most effective intervention?

Switch off cameras and continue in audio-only mode
Introduce a short interactive activity such as a poll, breakout room exercise, or virtual whiteboard collaboration (Correct answer)
Tell participants to take a break and return in 30 minutes
Increase lecture speed to finish content faster

Correct answer: Introduce a short interactive activity such as a poll, breakout room exercise, or virtual whiteboard collaboration

Interactive micro-activities reset attention and restore active participation, especially critical in virtual learning environments.

Question 77: A Product Owner arrives at Sprint Planning with a prioritized Product Backlog but has not refined any items with the Development Team beforehand. What is the most likely outcome?

The team may struggle to create a realistic Sprint Goal and forecast (Correct answer)
Sprint Planning will be cancelled by the Scrum Master
The team must accept the top items regardless of clarity
The Scrum Master should refine the backlog on behalf of the team

Correct answer: The team may struggle to create a realistic Sprint Goal and forecast

Without prior refinement, backlog items may lack sufficient detail for the team to confidently forecast and commit to a Sprint Goal.

Question 78: Which event reviews the product increment and adapts the backlog if needed?

Sprint Review (Correct answer)
Sprint Planning.
Sprint Retrospective.
Daily Scrum.

Correct answer: Sprint Review

The Sprint Review is held at the end of the Sprint to inspect the Increment and adapt the Product Backlog if needed. During this informal meeting, the Scrum Team presents the results of their work to key stakeholders, and they collaborate on what to do next. This event is crucial for gathering feedback and ensuring the product development remains aligned with evolving needs and market demands.

Question 79: Why does Planning Poker typically use a Fibonacci-like sequence (1, 2, 3, 5, 8, 13) rather than a linear scale?

The sequence ensures no single story can exceed one Sprint in duration
It was chosen because all Agile coaches agreed it produces the most accurate results
The Scrum Guide mandates this sequence for all estimation activities
The increasing gaps reflect growing uncertainty in larger estimates (Correct answer)

Correct answer: The increasing gaps reflect growing uncertainty in larger estimates

The exponentially increasing gaps in the Fibonacci sequence reflect the reality that larger items carry more uncertainty, making fine-grained distinctions (e.g., 11 vs. 12 points) meaningless.

Question 80: When a Scrum Trainer takes a 'meta-position' during team coaching, they are:

Delegating facilitation to a team member temporarily
Reviewing the team's metrics from a portfolio perspective
Stepping back from content to observe and comment on the team's overall dynamic and interaction patterns (Correct answer)
Standing outside the circle during retrospectives to observe

Correct answer: Stepping back from content to observe and comment on the team's overall dynamic and interaction patterns

The meta-position is an observational stance where the coach holds awareness of the team's whole-system dynamic rather than getting absorbed in the content of the conversation.
