PMBOK Practice Test Video Answer

1. A
The project charter is the document that formally authorizes the existence of a project and provides the project manager with the authority to apply organizational resources to project activities. While the charter includes high-level information about scope, schedule, and budget, its primary purpose is authorization and empowerment of the project manager.

2. A
CPI = EV / AC = $250,000 / $275,000 = 0.91. A CPI less than 1.0 indicates the project is over budget, meaning you’re getting less value for every dollar spent. In this case, for every dollar spent, only $0.91 of earned value is achieved.

3. B
A product life cycle encompasses the entire life of a product from conception through retirement. During this life cycle, multiple projects may be undertaken to develop, enhance, or maintain the product. Each project has its own life cycle, but the product life cycle is much longer and can contain many project life cycles.

4. C
The Monitoring and Controlling Process Group contains the processes required to track, review, and regulate the progress and performance of the project; identify any areas in which changes to the plan are required; and initiate the corresponding changes.

5. B
Stakeholder analysis should consider multiple dimensions including power (ability to impose will), urgency (need for immediate attention), and legitimacy (appropriate involvement). This multidimensional assessment provides a comprehensive understanding of stakeholder influence and impact on the project.

6. B
The fundamental distinction between projects and operations is that projects are temporary endeavors with a defined beginning and end, undertaken to create a unique product, service, or result. Operations are ongoing and repetitive activities that sustain the organization.

7. B
The scope management plan is a component of the project management plan. It describes how the scope will be defined, developed, monitored, controlled, and validated throughout the project lifecycle.

8. B
Control charts are used to determine whether a process is stable or has predictable performance over time. They display process variation over time and help identify whether variations are within acceptable limits (common cause) or indicate a problem (special cause).

9. D
Adaptive or Agile life cycles are characterized by iterative and incremental development where requirements are progressively elaborated. Scope is developed through successive iterations, and detailed planning happens just-in-time for each iteration rather than all upfront.

10. B
A RACI chart is a type of Responsibility Assignment Matrix that identifies who is Responsible for doing the work, who is Accountable for the work being completed, who should be Consulted before decisions are made, and who should be Informed after decisions are made.

11. C
All change requests, regardless of who initiates them, must go through the integrated change control process. This ensures that the impact of the change is properly evaluated, including effects on scope, schedule, cost, quality, resources, and risks before a decision is made.

12. D
Analogous estimating uses historical data from similar previous projects to estimate duration or cost for the current project. It is a top-down approach that is generally less costly and time-consuming but also less accurate than other methods.

13. B
The Critical Chain Method differs from the Critical Path Method primarily by explicitly considering resource constraints when developing the schedule. It also adds buffers (project buffer, feeding buffers) to protect the project completion date rather than padding individual activity estimates. The method removes safety time from individual activities and consolidates it into buffers.

14. B
The formula for calculating communication channels is n(n-1)/2, where n is the number of stakeholders. With 8 stakeholders: 8(8-1)/2 = 8(7)/2 = 56/2 = 28 communication channels.

15. B
The requirements management plan is a component of the project management plan that describes how requirements will be analyzed, documented, and managed throughout the project. It establishes the approach for requirements activities.

16. C
The communications management plan describes how project information will be distributed, who should receive what information, and what level of detail. It defines stakeholder communication requirements including access to project documents like the risk register, frequency of communications, and communication methods.

17. C
The critical path is the sequence of activities that determines the shortest possible project duration. It is the longest path through the network diagram and has zero or negative total float. Any delay in critical path activities will delay the project completion.

18. C
Monte Carlo simulation uses random sampling and statistical modeling to estimate probability distributions for project outcomes. Its primary benefit is providing a range of possible completion dates with associated probabilities rather than a single deterministic date.

19. B
The project scope statement is an output of the Define Scope process. It provides a detailed description of the project and product scope, major deliverables, assumptions, and constraints. The WBS is created in a separate process (Create WBS).

20. C
For complex problem-solving discussions with distributed teams, interactive communication through video conferencing is most effective. It enables real-time dialogue, visual cues, immediate feedback, and collaborative problem-solving despite geographic separation.

21. B
Project Schedule Management includes the processes required to manage the timely completion of the project. It encompasses schedule planning, activity definition, sequencing, duration estimating, schedule development, and schedule control.

22. C
SPI = EV/PV, so SPI of 0.85 (less than 1.0) indicates the project is behind schedule. CPI = EV/AC, so CPI of 1.15 (greater than 1.0) indicates the project is under budget. Therefore, the project is behind schedule but performing well on costs.

23. B
The Delphi technique is a method for gathering expert opinion where experts participate anonymously through questionnaires. A facilitator distributes questions, collects responses, summarizes them, and redistributes the summary for further input. This iterative process continues until consensus is reached. Anonymity helps reduce bias and prevents dominant personalities from influencing others.

24. B
Resource leveling is a technique that adjusts the start and finish dates of activities to address resource limitations or constraints. It often results in a longer project duration but ensures resources are not over-allocated.

25. B
The lessons learned register is used to record knowledge gained during the project so that it becomes part of the historical database for both the current project and the performing organization. This supports continuous improvement and organizational learning.

26. B
A weighted scoring model is a source selection technique that uses predetermined criteria and weights to evaluate and score seller proposals. Each criterion is assigned a weight, sellers are scored on each criterion, and weighted scores are calculated to compare proposals objectively.

27. D
A resource dependency occurs when an activity sequence is determined by resource availability or constraints. When a critical resource is unavailable, it creates a dependency that affects when activities can be performed.

28. A
TCPI (To-Complete Performance Index) indicates the cost performance efficiency that must be achieved with remaining resources to meet a specified management goal (usually BAC or EAC). A TCPI of 1.2 means the project must achieve $1.20 of earned value for every $1.00 spent going forward—a 120% efficiency rate—which is challenging and indicates the project needs to improve cost performance significantly.

29. D
The project management plan includes three baselines: scope baseline, schedule baseline, and cost baseline. Quality baseline is not a standard baseline component; instead, quality standards and metrics are included in the quality management plan.

30. C
Break-even point = Fixed Cost / (Purchase Price – Variable Cost) = $50,000 / ($35 – $20) = $50,000 / $15 = 3,333.33 units. At this point, the total cost to make equals the total cost to buy.
