  1. When compressing a schedule using crashing, which activities should be crashed first?

    Answer: Critical path activities with the lowest crash cost per day

    To minimize cost while compressing the schedule, crash critical path activities starting with those that have the lowest crash cost per day.

  2. A Finish-to-Finish dependency requires that the successor activity finishes no earlier than how many days after the predecessor's finish (with a 4-day lag)?

    Answer: 4 days after the predecessor finishes

    A Finish-to-Finish relationship with a 4-day lag means the successor cannot finish until 4 days after the predecessor finishes.

  3. Which of the following is a limitation of the Critical Path Method?

    Answer: CPM assumes unlimited resources are available

    Traditional CPM assumes resources are unlimited and always available, which rarely reflects real-world project conditions.

  4. During schedule analysis, a project manager identifies that the critical path has changed after a status update. What is the MOST likely cause?

    Answer: A non-critical activity was delayed beyond its total float

    When a non-critical activity is delayed beyond its total float, it becomes critical and may create a new, longer critical path.

  5. In CPM scheduling, a 'dummy activity' in an AOA network is used to:

    Answer: Show logical dependencies without consuming time or resources

    Dummy activities in AOA diagrams are zero-duration, zero-resource arrows that represent required logical dependencies between activities.

  6. A project network has activities with the following total floats: A=0, B=3, C=0, D=7, E=0. Which activities form the critical path?

    Answer: A, C, and E

    Activities with zero total float (A, C, E) form the critical path; any delay in these activities directly delays the project.

  7. When a project manager applies a 'Start-to-Start with lead' relationship, what scheduling benefit is achieved?

    Answer: Activities can overlap, reducing overall project duration

    Start-to-Start with lead allows the successor to begin before the predecessor completes, enabling parallelism that can compress the schedule.
