Quick Answer
The correct answer is the RACI matrix, because it is the only project management tool specifically designed to clarify roles by mapping who is Responsible, Accountable, Consulted, and Informed for each task. This responsibility assignment matrix prevents confusion by assigning a clear owner and decision-maker to every deliverable, which is exactly what the scenario describes. On the CompTIA Project+ PK0-005 exam, this question tests your ability to distinguish between core planning artifacts: a Gantt chart tracks schedule, a Work Breakdown Structure (WBS) decomposes scope, and a network diagram shows task dependencies—none of which define role accountability. A common trap is confusing "accountable" with "responsible," but remember: the accountable person signs off, while the responsible person does the work. To lock in the concept, use the mnemonic "RACI: Roles Are Clearly Identified."
This PK0-005 practice question tests your understanding of tools and documentation. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 team uses a tool that clarifies roles by showing who is responsible, accountable, consulted, and informed for each task. Which tool is this?
Work breakdown structure
Why wrong: WBS is a deliverable-oriented decomposition of work, not a role assignment tool.
Network diagram
Why wrong: Network diagrams show task dependencies, not roles.
RACI matrix
RACI stands for Responsible, Accountable, Consulted, and Informed; it clarifies roles for each task.
Gantt chart
Why wrong: Gantt charts display tasks over time, not role assignments.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
RACI matrix
A RACI matrix is a responsibility assignment matrix that defines roles. Gantt charts show schedule. WBS decomposes work. Network diagrams show dependencies.
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.
Work breakdown structure
Why it's wrong here
WBS is a deliverable-oriented decomposition of work, not a role assignment tool.
Network diagram
Why it's wrong here
Network diagrams show task dependencies, not roles.
RACI matrix
Why this is correct
RACI stands for Responsible, Accountable, Consulted, and Informed; it clarifies roles for each task.

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
Network diagrams show task dependencies, not roles.
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.
