Quick Answer
The answer is Responsible. In a RACI matrix, the Responsible role is the individual or team who actually performs the work to complete the task or deliverable, such as configuring a network device or writing code. This is distinct from the Accountable role, who ultimately answers for the outcome and signs off on the work, even though they may not do the hands-on effort. On the CompTIA Project+ PK0-005 exam, this distinction is frequently tested to ensure you understand that only one person can be Accountable, while multiple people can be Responsible. A common trap is confusing the two roles, especially since "accountable" sounds like it involves doing the work. To remember, think of the mnemonic: "Responsible does the deed, Accountable takes the lead."
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.
In a RACI matrix, which role is responsible for performing the work?
Responsible
The responsible person executes the task.
Accountable
Why wrong: The accountable person ultimately approves the work, not perform it.
Consulted
Why wrong: Consulted provides input but does not perform the work.
Informed
Why wrong: Informed receives updates but is not involved in execution.

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.
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.

Accountable
Why it's wrong here

Common exam traps
Cisco 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.
Detailed technical explanation
The RACI matrix is a responsibility assignment model used in project management to clarify roles. 'Responsible' (R) typically maps to the person who actually completes the activity, such as a network engineer configuring OSPF or a developer writing Python scripts. A common real-world scenario is a server migration where the 'Responsible' team performs the data transfer, while the 'Accountable' manager approves the cutover plan.
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.
