PK0-005 Tools and Documentation Practice Question
A project manager needs to show the sequence of project activities and their dependencies to identify the critical path. Which tool should they use?
⚠ Common exam trap
CompTIA often tests the distinction between a Gantt chart and a network diagram, trapping candidates who think a Gantt chart shows dependencies clearly enough for critical path analysis, when in fact only a network diagram provides the explicit logical relationships needed for forward/backward pass calculations.

Correct answer & explanation
✓
Network diagram
A network diagram is the correct tool because it visually maps the sequence of project activities and their dependencies using nodes and arrows, which is essential for identifying the critical path. The critical path is the longest path through the network diagram, determining the shortest possible project duration. This tool directly supports forward and backward pass calculations to find total float and critical activities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Network diagram
Why this is correct
Network diagrams are used for critical path analysis.
- ✗
Milestone chart
Why it's wrong here
Milestone charts only show key events.
- ✗
Burndown chart
Why it's wrong here
Burndown charts track work remaining.
- ✗
Gantt chart
Why it's wrong here
Gantt charts show timeline but are not best for critical path analysis.
