PK0-005 Tools and Documentation Practice Question
In a RACI matrix, the person who is ultimately accountable for the completion of a task is denoted by which letter?
⚠ Common exam trap
Watch out — candidates often confuse 'Responsible' (the doer) with 'Accountable' (the owner), but the PMBOK and RACI model strictly separate these roles, and the exam expects you to know that only 'A' denotes ultimate accountability.

Correct answer & explanation
✓
A - Accountable
In a RACI matrix, 'A' stands for Accountable, meaning the person who has ultimate ownership and sign-off authority for the task. This individual is answerable for the successful completion of the deliverable and cannot delegate that responsibility. The correct answer is D because the RACI acronym explicitly defines 'A' as Accountable.
