1. What is the primary ethical obligation of a CST professional when a conflict of interest arises during safe, less & nexus scaling activities? → Disclose the conflict to all relevant parties and recuse from the decision if necessary
2. The concept of 'clean questions' in coaching is BEST described as: → Questions that avoid embedding the coach's assumptions into the coachee's thinking
3. Which Scrum value is most demonstrated when a Developer raises a technical risk that may jeopardize the Sprint Goal? → Openness
4. Which action BEST reduces cycle time for individual work items in a Scrum Team? → Limiting Work in Progress so developers can focus and finish items faster
5. A team's velocity varies significantly sprint to sprint (e.g., 20, 45, 15, 50 points). What does this MOST likely indicate? → There is high variability in story sizing or work predictability
6. According to the Scrum Guide, the Definition of Done primarily serves to: → Create transparency and a shared understanding of what 'complete' means
7. Which organizational anti-pattern most directly undermines the Scrum value of Focus? → Allowing team members to work on multiple teams simultaneously
8. When a Scrum Team operates in a complex domain, which characteristic of complexity makes empiricism the appropriate approach? → The cause-and-effect relationships are only knowable in retrospect
9. Which of the following best describes 'organizational impediments' in Scrum coaching? → Systemic barriers outside the team's control that slow delivery
10. A CST observes a Scrum Team that only communicates with stakeholders through formatted reports. What risk does this pose? → The team loses the rich, two-way feedback loop Scrum depends on
11. Which of the following is an example of a 'scaling question' used in solution-focused coaching? → 'On a scale of 1 to 10, where are you now, and what would a 7 look like?'
12. Which flow metric indicates the number of work items actively being worked on at any given time? → Work in Progress (WIP)
13. Why should a Scrum Team avoid using velocity as a performance metric to compare teams? → Story point scales differ between teams, making cross-team comparison invalid
14. Which of the following is a fundamental principle of systemic team coaching as it applies to Certified Scrum Trainer? → Systematic evaluation and adherence to established industry standards
15. 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
16. In Scrum, who is responsible for ensuring that the Scrum Team understands the Sprint Goal? → The Product Owner
17. Which statement about throughput as a flow metric is MOST accurate? → Throughput counts the number of items completed per unit of time
18. A Product Owner shares preliminary designs with stakeholders early in development. How does this behavior support Agile principles? → It enables early validation and reduces the cost of late-stage changes
19. A team wants to forecast how many items they can complete in the next 5 sprints. Which historical data is MOST appropriate to use? → The team's throughput (items completed per sprint) over the last 10 sprints
20. According to the Scrum Guide, who participates in the Daily Scrum? → The Developers
21. During Planning Poker, two team members consistently submit very different estimates. What is the BEST action for the Scrum Master to take? → Facilitate a discussion so both team members share their reasoning
22. A stakeholder demands that the Product Owner add a critical bug fix to the current Sprint. The correct Scrum response is: → The Product Owner adds it after getting Development Team agreement
23. Which is the MOST accurate description of a stakeholder's role in the Scrum framework? → Anyone with an interest in the product who collaborates primarily at the Sprint Review
24. Which quality assurance method is most commonly applied in retrospective formats & anti-patterns to verify that CST professional standards are being met? → Structured audits, peer reviews, and performance metrics aligned with industry benchmarks
25. In LeSS, how many Product Owners are there for all teams? → One overall Product Owner for the whole product
26. A Product Owner wants to split a large user story during refinement. Which INVEST criterion most directly guides whether the split was done well? → Valuable
27. A team coach notices that the team never disagrees with a proposed solution in Sprint Planning. The systemic interpretation most worth exploring is: → The team may have a suppressed conflict dynamic where dissent feels unsafe or unproductive
28. Which statement best describes the 'blame storming' anti-pattern in retrospectives? → Discussions devolve into attributing failures to individuals rather than systemic issues
29. In which scenario would empiricism most likely fail in a Scrum Team? → When the team hides problems and does not surface impediments transparently
30. A Scrum Team is asked to commit to a fixed scope for a project that will span 12 months. How does this conflict with empiricism? → It conflicts because empiricism requires that scope evolve based on learning and feedback
