PK0-005 Tools and Documentation Practice Question
A project manager is creating a RACI matrix for the project. One activity involves conducting security testing. The security lead will perform the testing, the project manager is responsible for ensuring it happens, and the compliance officer needs to be informed of the results. Which assignment is correct?
⚠ Common exam trap
The trap is confusing the Responsible and Accountable roles, especially when the project manager is involved — candidates often assume the project manager is always Responsible, but they are typically Accountable for ensuring work is done.
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
✓
Security lead: Responsible; Project manager: Accountable; Compliance officer: Informed
In a RACI matrix, the person who performs the work is Responsible (R), the person ultimately answerable for the correct completion is Accountable (A), and those who need to be kept informed are Informed (I). Here, the security lead performs the testing, so they are Responsible; the project manager ensures it happens and is ultimately answerable, so they are Accountable; the compliance officer needs to be informed, so they are Informed. This matches option C.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Security lead: Accountable; Project manager: Informed; Compliance officer: Responsible
Why it's wrong here
The security lead performs the testing, making them Responsible, not Accountable; the project manager ensuring it happens is Accountable, not Informed. This arrangement would fit a scenario where the compliance officer executes the testing and the security lead owns its outcome, which the stem does not describe.
- ✗
Security lead: Responsible; Project manager: Informed; Compliance officer: Accountable
Why it's wrong here
The compliance officer only needs informing of results, so Accountable contradicts the stem; the project manager ensures the work happens, which is Accountable rather than Informed. This mapping would suit a scenario where the compliance officer owns the testing outcome and the project manager merely receives updates.
- ✓
Security lead: Responsible; Project manager: Accountable; Compliance officer: Informed
Why this is correct
Assigning the security lead as Responsible matches the stem's requirement that they perform the testing, while the project manager as Accountable satisfies their duty to ensure it happens. The compliance officer as Informed reflects their need to receive results without approving or executing the work.
- ✗
Security lead: Accountable; Project manager: Responsible; Compliance officer: Informed
Why it's wrong here
The stem states the security lead performs the testing, which is Responsible, and the project manager ensures it happens, which is Accountable. Swapping these inverts the doing and owning roles. This assignment would fit a scenario where the project manager personally executes the testing while the security lead owns the outcome.
