PK0-005 Practice Question: A project schedule is displayed as a bar chart…
A project schedule is displayed as a bar chart showing tasks against a calendar. Which tool is being used?
⚠ Common exam trap
It's easy for candidates to confuse a Gantt chart with a PERT chart or network diagram, as both involve task relationships, but only the Gantt chart is a bar chart against a calendar.
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
✓
Gantt chart
A Gantt chart is a bar chart that displays project tasks against a calendar, showing start and end dates, dependencies, and progress. This matches the description in the question, making option B correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
PERT chart
Why it's wrong here
A PERT chart is a network diagram using three-point estimates to show activity dependencies and expected durations, without calendar bars. It tempts because it also depicts schedule, and it would be correct when the question asks for probabilistic duration estimation across dependent activities.
- ✓
Gantt chart
Why this is correct
A Gantt chart presents tasks as horizontal bars plotted against a calendar timeline, directly matching the stem's description of a bar chart showing tasks against dates. This format also exposes task durations, start and finish dates, and dependencies, which is precisely what the schedule display requires.
- ✗
Network diagram
Why it's wrong here
A network diagram shows tasks as nodes with logical precedence arrows, not duration bars against dates. It tempts because it also models schedule logic, and it would be correct when the question asks how activities relate sequentially or where the critical path is calculated.
- ✗
Work breakdown structure
Why it's wrong here
A work breakdown structure decomposes deliverables into hierarchical components; it carries no calendar axis or task durations. It tempts because it also organises project scope, and it would be correct when the question asks how scope is decomposed into manageable work packages.
