In a RACI matrix, which role is responsible for performing the work?
⚠ Common exam trap
The PK0-005 exam often tests the distinction between 'Responsible' and 'Accountable' by presenting a scenario where a single person is both, leading candidates to confuse the two roles and incorrectly select 'Accountable' for performing the work.

Correct answer & explanation
✓
Responsible
In a RACI matrix, 'Responsible' is the role that actually performs the work or task. This is the person or team who does the hands-on effort to complete the deliverable, such as configuring a router or writing code. The 'Responsible' role is distinct from 'Accountable,' who ultimately answers for the outcome.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Responsible
Why this is correct
In a RACI matrix, Responsible designates the person who performs the work and completes the task. Accountable owns the outcome and approves it, Consulted provides input, and Informed receives updates, so Responsible is the correct role for executing the work.
- ✗
Accountable
Why it's wrong here
Accountable designates the single person who owns the outcome and answers for it, not the one executing tasks. It is tempting because accountability sounds like doing the work, and it is the correct RACI role when the question asks who ultimately owns and signs off on a deliverable.
- ✗
Consulted
Why it's wrong here
Consulted denotes two-way input sought before decisions, not task execution. It attracts candidates because consulted parties contribute expertise, and it would be correct where the question asks which role provides subject-matter advice or feedback before work is finalised.
- ✗
Informed
Why it's wrong here
Informed means receiving one-way status updates after decisions, with no execution duty. It tempts because informed people are kept in the loop, and it would be the right answer if the question asked which role simply needs to be notified of progress or outcomes.
