|Question 1|| |
All the following statements about a WBS are true except which one?
A. It provides a framework for organizing and ordering a project's activities.
B. It breaks down a project into successively greater detail by level and can be similar in appearance to an organizational chart.
C. It's a scheduling method.
D. It's a planning tool.
| A1: |
Answer C is correct. A WBS is not a scheduling method. Instead, it provides input into the scheduling process. Therefore, answers A, B, and D are correct.
|Question 2|| |
All the following statements are false about the scope statement except which one?
A. It provides a documented basis for preparing the PERT/CPM network.
B. It's not the basis for the contract between the buyer and seller.
C. It includes a description of project objectives such as cost, schedule, and quality measures.
D. It's not developed by functional managers during the concept phase of a project.
| A2: |
Answer C is correct. The question is made more difficult by negating otherwise correct choices, which is a common technique on the PMP exam. Answer A is incorrect because the activity list is used as the basis for preparing the PERT/CPM network. Answer B is incorrect because the scope statement is the documented basis for the contract between buyer and seller. Answer D is incorrect because functional managers do develop the scope statement during the concept phase.
|Question 3|| |
Which statement best describes the proper way to develop the initial project schedule?
A. Create a new MS Project file, enter key deliverables, enter start and end dates for each, and assign resources.
B. Create a new MS Project file, enter the WBS structure and work packages, break down work packages into activities, enter the estimated duration and resource assignments for each activity, and enter the logical dependencies between the activities and work packages,
C. Create a new MS Project file, enter the WBS structure and work packages, break down work packages into activities, enter start and end dates for each activity, and compress the schedule to meet the deadline.
D. Find an MS Project file with a proven WBS and activity list template, review the estimated duration and resource assignments for each activity, and review the logical dependencies between the activities and work packages.
| A3: |
Answer D is correct. This question can be difficult because it provides common, but incorrect, practices as options, and it incorporates some of the important PMI principles. Answer A is incorrect because it does not refer to the WBS or to activity durations. Answer B is tempting, but it's not the best response. In this case, answer D is a better response because of the use of "historical information" in the process. Answer C is incorrect because it does not refer to activity durations.
|Question 4|| |
A precedence diagram and an arrow diagram are both examples of networks. Which statement best describes the primary difference between them?
A. The arrow diagram does not indicate critical path.
B. The precedence diagram uses float as part of the activity duration.
C. The arrow diagram incorporates PERT in the activity duration.
D. The precedence diagram represents activities on nodes.
| A4: |
Answer D is correct. Answer A is incorrect because both types can represent the critical path. Answer B is incorrect because float is associated with scheduling techniques, not network diagrams. Answer C is incorrect because it is GERT that uses PERT for activity duration.
|Question 5|| |
Activity A has a duration of 4 days and begins on the morning of Wednesday the 4th. The successor activity, Activity B, has a finish-to-start relationship with Activity A. The finish-to-start relationship has a lag of 3 days, and Activity B has a duration of 3 days. Saturday isn't a workday. What can be determined from this data?
A. The total duration is 11 days.
B. The finish date of Activity B is Sunday the 15th.
C. The total duration is 14 days.
D. The finish date of Activity B is Tuesday the 17th.
| A5: |
Answer B is correct. Activity A completes on Sunday the 8th because Saturday isn't a workday. The 3-day lag occurs Monday, Tuesday, and Wednesday. Activity B starts on Thursday the 12th and completes on Sunday the 15th because Saturday isn't a workday. The total calendar duration is 12 days.
|Question 6|| |
"I cannot test the software until I code the software." This expression describes which of the following dependencies?
| A6: |
Answer A is correct. Mandatory or "hard logic" dependencies are ones where one task must occur before another can start.
|Question 7|| |
Which of the following is a schedule development technique that provides early and late start and finish dates for each activity?
D. Monte Carlo
| A7: |
Answer C is correct. See the PMBOK definition (PMBOK, page 75) of the critical path method scheduling technique.
|Question 8|| |
All the following statements about analogous estimating are true except which one?
A. It has an accuracy rate of ±10% of the actual costs.
B. It supports top-down estimating and is a form of expert judgment.
C. It's used to estimate total project costs when a limited amount of detailed project information is available.
D. It involves using the cost of previous, similar projects as the basis for estimating the cost of the current project.
| A8: |
Answer A is correct. Analogous estimating has a 25%/+75% accuracy level.
|Question 9|| |
What is the purpose of resource planning?
A. To determine the physical resources needed to perform the project activities.
B. To provide quantitative assessments of the costs of resources required to complete project activities.
C. To approximate the costs of resources needed to complete the project.
D. To determine the resources that are potentially available.
| A9: |
Answer A is correct, per the PMBOK definition of resource planning. Answers B and C are incorrect because they describe cost estimating. Answer D is incorrect because it is focused on availability of resources, not on what is required to perform the project activities.
|Question 10|| |
What is the purpose of cost budgeting?
A. To allocate cost estimates to individual work items to establish a cost baseline against which project performance can be measured.
B. To monitor cost performance to detect variances from the plan.
C. To determine the cost of the resources needed to complete the project activities and allocate them to the proper chart of accounts for the organization.
D. To provide a quantitative assessment of the likely costs of the resources required to complete project activities.
| A10: |
Answer A is correct, per the PMBOK definition. Answer B is incorrect because it describes cost control, not cost budgeting. Answer C is incorrect because it describes cost estimating, not cost budgeting. Answer D is incorrect because it describes estimating activity as well.
