Quick Answer
The answer is the risk register. When a change request is approved and the project baseline is updated, the risk register must also be updated because any approved change can introduce new risks, alter the probability or impact of existing risks, or make some risks obsolete. The risk register is the formal document that captures identified risks, their analysis, and response plans, so a baseline change directly affects the project’s risk profile. On the CompTIA Project+ PK0-005 exam, this tests your understanding that change control and risk management are tightly linked—a common trap is to update only the schedule or budget baseline while forgetting the risk register. To remember, think of the “Change-Risk Chain”: every approved change triggers a risk review. A simple memory tip is “No baseline update without a risk register update.”
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.
After a change request is approved, the project manager updates the project baseline. Which document must also be updated to reflect the impact of the change on project risks?
Issue log
Why wrong: Issue log records problems that have occurred, not potential risks.
Risk register
The risk register tracks identified risks and their status after changes.
Lessons learned
Why wrong: Lessons learned are captured after project phases or completion.
Stakeholder register
Why wrong: Stakeholder register lists stakeholders, not risks.

Correct answer & explanation
Risk register
When a change request is approved and the project baseline is updated, the risk register must also be updated because the change may introduce new risks, alter the probability or impact of existing risks, or render some risks obsolete. The risk register is the formal document that captures identified risks, their analysis, and response plans, so any baseline change directly affects the risk profile of the project.
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.
Issue log
Why it's wrong here
Issue log records problems that have occurred, not potential risks.
Risk register
Why this is correct
The risk register tracks identified risks and their status after changes.

Stakeholder register
Why it's wrong here
Stakeholder register lists stakeholders, not risks.
Common exam traps
CompTIA often tests the distinction between reactive documents (issue log) and proactive documents (risk register), so the trap here is confusing a change's potential future risks with current issues that have already materialized.
Detailed technical explanation
The risk register is a living document that includes fields such as risk ID, description, probability, impact score, risk owner, and response strategy. When a change request is approved, the project manager should perform a risk reassessment to update these fields, ensuring the risk register reflects the current state of the project. In real-world scenarios, a scope change might increase technical complexity, raising the probability of integration failures, which must be documented in the risk register to trigger appropriate mitigation actions.
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.
