PK0-005 Practice Question: A project manager needs to determine the critical…
A project manager needs to determine the critical path of a project. Which statement about the critical path is true?
⚠ Common exam trap
CompTIA often tests the misconception that the critical path is the shortest path or that there can only be one critical path, when in reality it is the longest path with zero float and multiple critical paths can exist simultaneously.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It has the longest duration and zero float.
The critical path is the longest path through the project network diagram, determining the shortest possible project duration. It has zero float (or total slack), meaning any delay on a critical path activity directly delays the project. Option B correctly captures both the longest duration and zero float characteristics.

- ✓
It has the longest duration and zero float.
Why this is correct
Definition of critical path.
- ✗
There is always exactly one critical path.
