The answer is the requirements traceability matrix (RTM). This document is the correct choice because it systematically links each project requirement to its origin, design, testing, and delivery status, making it the essential tool for tracking the impact of a vendor change mid-project. When the vendor swaps the migration tool, the RTM must be updated to assess how the change affects each requirement—such as compatibility with the new tool, altered data migration rules, or revised security controls—ensuring every requirement remains satisfied and traceable. On the CompTIA Project+ PK0-005 exam, this tests your understanding of change control and traceability; a common trap is confusing the RTM with the change log or risk register, but remember that the RTM specifically tracks requirement fulfillment, not just the change event itself. A helpful memory tip: RTM stands for “Requirements Traceability Matrix,” and you can think of it as the project’s “requirement roadmap” that must be redrawn whenever a vendor or tool changes course.
PK0-005 Practice Question: Basics of IT Infrastructure and IT Project Management
This PK0-005 practice question tests your understanding of basics of it infrastructure and it project management. 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.
A company is migrating from on-premise email to a cloud-based solution. The vendor changes the migration tool mid-project. Which project management document should be updated to track the impact on requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Requirements traceability matrix
The requirements traceability matrix (RTM) links each requirement to its origin, design, testing, and delivery status. When the vendor changes the migration tool mid-project, the RTM must be updated to reflect how this change impacts each requirement—such as compatibility, data migration rules, or security controls—ensuring all requirements are still met and traceable.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Risk management plan
Why it's wrong here
While the tool change may introduce risk, the primary document for tracking requirement impact is the RTM.
✗
Project charter
Why it's wrong here
The project charter is a high-level document and does not track detailed requirement changes.
✓
Requirements traceability matrix
Why this is correct
The RTM links requirements to their implementation and is updated when changes affect how requirements are met.

Why it's wrong here
WBS focuses on deliverables and tasks, not the tracing of requirements.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the risk management plan with tracking requirement impacts, but the RTM is the specific artifact for linking and monitoring requirement changes throughout the project lifecycle.
Detailed technical explanation
How to think about this question
The RTM typically includes fields such as requirement ID, description, source, priority, test case references, and status. In a cloud migration, a tool change might affect data format conversion (e.g., PST to EML vs. MBOX), mailbox size limits, or API authentication methods (e.g., OAuth 2.0 vs. Basic Auth). The RTM ensures each affected requirement is re-verified against the new tool's capabilities, preventing untracked scope creep or compliance gaps.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
