A network administrator is preparing to upgrade the firmware on a critical router. Which document should the administrator consult to understand the steps required to minimize downtime and ensure a successful upgrade?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
SLA
A Service Level Agreement (SLA) defines the expected uptime and performance commitments. It does not contain technical steps for performing an upgrade.
B
Best answer
Change management plan
The change management plan documents the process for making changes to the network, including risk assessment, detailed steps, testing, approval, and rollback procedures. It is the appropriate resource to ensure a methodical and safe upgrade.
C
Distractor review
Network diagram
A network diagram shows the physical/logical layout of devices, connections, and IP addresses. It is useful for understanding dependencies but does not provide upgrade steps.
D
Distractor review
Baseline performance report
A baseline report captures normal performance metrics (CPU, bandwidth, etc.) to compare against after changes. It helps verify the impact of an upgrade but does not describe how to perform the upgrade.
Common exam trap
Common exam trap: answer the scenario, not the keyword
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.
Technical deep dive
How to think about this question
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.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this N10-009 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Change management plan — A change management plan outlines the procedures for implementing changes in a controlled manner, including steps, rollback plans, and downtime windows. While vendor upgrade guides are specific, the change management plan is the internal document that consolidates all necessary steps and approvals. An SLA defines service levels, a network diagram shows topology, and a baseline report shows performance metrics—none provide the procedural steps for the upgrade.
