A network administrator needs to update the firmware on a critical core switch. According to change management best practices, which step should be completed FIRST?
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
Best answer
Test the firmware update in a lab environment
Testing first ensures the firmware works correctly and any compatibility issues are discovered without affecting production operations.
B
Distractor review
Notify all users of a scheduled outage
Notification is important but should occur after the change has been approved and scheduled. It is not the first step in the change management process.
C
Distractor review
Create a detailed rollback plan
A rollback plan is a key part of change preparation, but it is typically developed after testing and before implementation. Testing should come first to inform the plan.
D
Distractor review
Schedule the update during a maintenance window
Scheduling occurs after the change has been approved and the plan is ready. The first step is to test the change in a safe environment.
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: Test the firmware update in a lab environment — Change management procedures emphasize testing changes in a non-production environment before implementing them in production. This helps identify potential issues and reduce the risk of outages. Other steps like creating a rollback plan and scheduling a maintenance window are important but come after testing.
