CompTIA Project+ (PK0-004) — Question 388
Task A has a duration of 2 days and is a predecessor of task B, which has a duration of 3 days and is a predecessor of task C. Task C has a duration of 4 days. Task D has a start-to-start relationship with task A and a duration of 11 days. Which of the following is the lag time for task D?
Answer options
- A. −9 days
- B. −2 days
- C. 0 days
- D. 2 days
- E. 9 days
Correct answer: D
Explanation
The correct answer is D, as task D, which has an 11-day duration, starts at the same time as task A. Given that task A lasts 2 days, task D will finish 2 days after task A does, resulting in a lag time of 2 days. The other options do not accurately reflect the relationship and durations of the tasks.
