CompTIA Project+ (PK0-004) — Question 2

A project has activities on the critical path that must be completed before other activities can start.
Task A is dependent on Task C before Task D can be completed.
Task A requires task B to start.
Task B takes twice as long to complete as Task C.
Which of the following is the appropriate ordering of the critical path?

Answer options

• A. B, A, D
• B. C, B, D, A
• C. D, A, C
• D. B, C, A, D

Correct answer: D

Explanation

The correct sequence is D, as Task B must be completed first, followed by Task C, which is a prerequisite for Task A. Task D can only begin after Task A is finished. The other options either misplace the order of dependencies or include tasks that cannot start without completing their dependencies.
