Quick Answer
The correct answer is a network diagram, as it is the project management tool specifically designed to illustrate the sequence of project activities and their dependencies. Unlike a Gantt chart, which displays tasks against a timeline, a network diagram maps out the logical flow of work, showing which tasks must finish before others can start and highlighting the critical path. On the CompTIA Project+ PK0-005 exam, this question tests your ability to distinguish between core scheduling artifacts; a common trap is confusing the network diagram’s dependency-focused layout with a Gantt chart’s time-based bars. Remember that a network diagram is all about the “what comes next” logic, not the calendar. For a quick memory tip, think of the word “network” as a web of connected nodes—each node is an activity, and the arrows between them are the dependencies, making it the go-to tool for sequencing.
This PK0-005 practice question tests your understanding of tools and documentation. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A project manager uses a tool that shows the sequence of project activities and their dependencies. Which tool is this?
Resource histogram
Why wrong: Resource histogram shows allocation over time.
Network diagram
Correct. Network diagram shows sequence and dependencies.
Work breakdown structure
Why wrong: WBS is for decomposition, not dependencies.
Gantt chart
Why wrong: Gantt chart shows schedule but not dependencies clearly.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Network diagram
Option B is correct because a network diagram shows activity sequence and dependencies. Option A is wrong because a Gantt chart shows bar chart schedule, not dependencies. Option C is wrong because a WBS is hierarchical. Option D is wrong because a resource histogram shows resource allocation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
Resource histogram shows allocation over time.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the PK0-005 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
