PK0-005 Practice Question: A project manager needs to track task…
A project manager needs to track task dependencies and identify the critical path. Which tool should they use?
⚠ Common exam trap
CompTIA often tests the misconception that a Work Breakdown Structure (WBS) is sufficient for scheduling and dependency tracking, but the WBS only defines scope, not the sequence or timing of tasks required for critical path analysis.

Correct answer & explanation
✓
Gantt chart
A Gantt chart is the correct tool because it visually displays task dependencies and the critical path by showing tasks as bars along a timeline, with arrows linking dependent tasks. This allows the project manager to identify which tasks are on the longest path (critical path) and cannot be delayed without affecting the project finish date. Other tools like a RACI matrix, Pareto chart, or WBS do not provide the timeline and dependency visualization needed for critical path analysis.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Gantt chart
Why this is correct
Gantt chart shows task durations and dependencies, allowing identification of the critical path.
- ✗
RACI matrix
Why it's wrong here
A RACI matrix assigns responsibilities, not task dependencies or scheduling.
- ✗
Pareto chart
Why it's wrong here
A Pareto chart is a quality tool used to prioritize causes; it does not help with schedule management.
- ✗
Work breakdown structure (WBS)
Why it's wrong here
WBS is a hierarchical decomposition of work, but it does not show dependencies or the critical path.
