Quick Answer
The answer is the cost baseline, as it is one of the three key components of a project management plan. The scope baseline, schedule baseline, and cost baseline together form the performance measurement baseline, which is the approved, formal version of the project’s scope, schedule, and budget used to track and control progress. On the CompTIA Project+ PK0-005 exam, this concept tests your ability to distinguish between the project management plan itself and supporting project documents. A common trap is confusing the risk register or lessons learned with plan components, but remember: baselines are part of the plan, while registers and reports are separate documents. For a quick memory tip, think of the three “S-C-C” baselines: Scope, Cost, and Schedule—these are the core pillars that define how the project will be executed and measured.
This PK0-005 practice question tests your understanding of project life cycle phases. 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.
Which THREE of the following are key components of a project management plan?
Scope baseline
The scope baseline (scope statement, WBS, WBS dictionary) is part of the plan.
Lessons learned
Why wrong: Lessons learned are documented after project closure.
Schedule baseline
The schedule baseline is part of the plan.
Risk register
Why wrong: The risk register is a project document, not a component of the plan.
Cost baseline
The cost baseline is part of the plan.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Scope baseline
The scope baseline, schedule baseline, and cost baseline are key components of the project management plan. The risk register is a project document, not part of the plan itself. Lessons learned are created after project closure.
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.
Scope baseline
Why this is correct
The scope baseline (scope statement, WBS, WBS dictionary) is part of the plan.

Schedule baseline
Why this is correct
The schedule baseline is part of the plan.

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.
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.
