PMI-SP Sample Questions

  1. Question 1

    Q1

    A Scheduling Professional is establishing the scheduling approach for a complex infrastructure project with high regulatory compliance requirements. The project charter dictates strict adherence to a fixed deadline due to government funding. Which scheduling methodology should be selected to best manage the critical path while ensuring all regulatory activities are documented and tracked?

    Show answer & explanation

    Correct answer: B

    The Critical Path Method (CPM) is the optimal choice for projects with strict deadlines and regulatory requirements where specific activity sequences and the longest path (critical path) must be strictly managed to ensure on-time completion. CPM provides the necessary granularity for regulatory documentation.

  2. Question 2

    Q2

    During the development of the Schedule Management Plan, the team is defining how schedule contingencies will be handled. Which component of the plan should explicitly detail the procedures for accessing management reserves versus contingency reserves?

    Show answer & explanation

    Correct answer: B

    The Schedule Change Control Procedures within the Schedule Management Plan define how changes to the schedule baseline are managed, including the specific governance required to access management reserves (for unforeseen risks) versus contingency reserves (for identified risks).

  3. Question 3

    Q3

    True or False: In Rolling Wave Planning, work to be performed in the near term is planned in detail, while work in the future is planned at a higher level of the WBS.

    Show answer & explanation

    Correct answer: A

    This is the definition of Rolling Wave Planning, an iterative planning technique where the work to be accomplished in the near term is planned in detail, while the work in the future is planned at a higher level.

  4. Question 4

    Q4

    A project manager is determining the appropriate level of accuracy for activity duration estimates during the initiation phase. Which of the following ranges typically represents a Rough Order of Magnitude (ROM) estimate?

    Show answer & explanation

    Correct answer: B

    According to the PMBOK Guide, a Rough Order of Magnitude (ROM) estimate is typically in the range of -25% to +75%. This is used early in the project when details are scarce.

  5. Question 5

    Q5Multiple answers

    You are decomposing the project scope to create the schedule. Which TWO items are primary outputs of the 'Define Activities' process? (Select TWO)

    Show answer & explanation

    Correct answers: A, C

    The Activity List is a comprehensive list including all schedule activities required on the project.

    Activity Attributes extend the description of the activity by identifying multiple components associated with each activity.

  6. Question 6

    Q6

    An organization requires that all schedule variances exceeding 10% be reported to the steering committee. In which document should this threshold be explicitly defined?

    Show answer & explanation

    Correct answer: B

    The Schedule Management Plan establishes the criteria and the activities for developing, monitoring, and controlling the schedule. This includes control thresholds for variance reporting.

  7. Question 7

    Q7

    A scheduler is advising a project team on setting up their schedule model. The project involves high uncertainty and evolving requirements. Which scheduling approach would allow for high-level planning of the overall timeline while detailing only the immediate iteration?

    Show answer & explanation

    Correct answer: B

    Adaptive (or Agile) scheduling uses iterative and incremental planning. It works best for projects with high uncertainty, where detailed planning is done only for the upcoming iteration.

  8. Question 8

    Q8

    Consider the following network diagram logic:

    Activity A (5 days) -> Activity B (4 days)
    Activity A (5 days) -> Activity C (6 days)
    Activity B (4 days) -> Activity D (5 days)
    Activity C (6 days) -> Activity D (5 days)

    What is the Free Float of Activity B?

    Show answer & explanation

    Correct answer: C

    Path 1: A-B-D = 5+4+5 = 14 days.
    Path 2: A-C-D = 5+6+5 = 16 days (Critical Path).
    Early Start of D is 11 (after C finishes at 5+6=11).
    Early Finish of B is 9 (5+4).
    Free Float of B = ES of successor (D) - EF of B = 11 - 9 = 2 days.

    graph LR A[A: 5d] --> B[B: 4d] A --> C[C: 6d] B --> D[D: 5d] C --> D
  9. Question 9

    Q9

    When defining activities for a new software module, the team identifies a 'Finish-to-Start' relationship between 'Code Module' and 'Test Module'. However, the testing team states they can begin testing the initial components 2 days before coding is fully complete. Which dependency modification best represents this scenario?

    Show answer & explanation

    Correct answer: B

    A Lead allows a successor activity to start before the predecessor has finished. A 2-day lead on a Finish-to-Start relationship means testing can start 2 days before coding finishes.

  10. Question 10

    Q10

    You are using the Three-Point Estimating (Beta/PERT) technique. An activity has an Optimistic estimate of 4 days, a Most Likely estimate of 7 days, and a Pessimistic estimate of 16 days. What is the expected duration?

    Show answer & explanation

    Correct answer: B

    The PERT Beta formula is (O + 4M + P) / 6.
    (4 + 4(7) + 16) / 6 = (4 + 28 + 16) / 6 = 48 / 6 = 8 days.
