Quick Answer
The answer is the change log and the project baseline. These two documents must be updated when a change request is approved because the change log provides the official audit trail, recording the approval decision, implementation steps, and closure details, while the project baseline—whether scope, schedule, or cost—must be revised to reflect the approved change so that all future work and variance analysis are measured against the new baseline. On the CompTIA Project+ PK0-005 exam, this concept tests your understanding of the integrated change control process, often appearing in scenario-based questions where a trap answer lists the project management plan instead of the baseline itself. Remember, the plan describes how to manage changes, but the baseline is what actually gets updated to capture the new approved scope or budget. A helpful memory tip: “Log the approval, baseline the change”—the log tracks the decision, the baseline locks in the new target.
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.
Which TWO documents should be updated when a change request is approved?
Change log
The change log records all change requests and their status.
Status report
Why wrong: The status report is updated after the change is implemented, not immediately.
Risk register
Why wrong: The risk register is updated only if the change affects risks.
Project baseline
The baseline must be updated to reflect the approved change.
Stakeholder register
Why wrong: The stakeholder register is not automatically updated with every change.

Correct answer & explanation
Change log
The change log is updated to record the approval, implementation details, and closure of the change request, providing an audit trail. The project baseline (e.g., scope, schedule, cost) must be updated to reflect the approved change, ensuring all future work and variance analysis are measured against the revised baseline.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
The trap here is that candidates confuse the risk register with the change log, thinking that all approved changes automatically update the risk register, when in fact the risk register is only updated if the change introduces or modifies a specific risk.
Detailed technical explanation
In project management, the change log is a formal record of all change requests, including their status (e.g., submitted, approved, rejected) and implementation details. The project baseline (often managed through a configuration management system) is the approved version of the project management plan plus subsidiary plans; updating it ensures that performance measurement baselines (e.g., schedule baseline, cost baseline) remain valid after an approved change. Failure to update the baseline can lead to inaccurate earned value management (EVM) calculations and scope creep.
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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A project manager is reviewing a change request that has been approved. The change will affect the project scope, schedule, and budget. Which document should the project manager update first to ensure all changes are captured and communicated?
hardWhy A: The change log is the official repository for recording all approved change requests, including their details and impacts. Updating it first ensures that the change is formally documented and communicated to stakeholders before any baselines or plans are modified. This aligns with the integrated change control process, where the change log serves as the primary communication tool for change status.
