N10-009 Network Operations Practice Question
A network administrator needs to perform a critical firmware upgrade on a core switch during a maintenance window. Which of the following should the administrator do FIRST before making the change?
⚠ Common exam trap
CompTIA often tests the principle that testing in a lab environment is the first step in any change process, and the trap here is that candidates mistakenly choose creating a backup (Option C) as the first action, confusing a safety measure with the prerequisite validation step.

Correct answer & explanation
✓
Test the firmware in a lab environment
Before making any change to a production device, the firmware should first be tested in a lab environment that mirrors the production setup. This validates compatibility with existing hardware, software features, and configurations, preventing unexpected behavior such as boot loops, protocol failures, or hardware incompatibility that could cause extended outages.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Test the firmware in a lab environment
Why this is correct
Before deploying new firmware to a critical core switch, thorough testing in a dedicated lab environment is paramount. This process validates the firmware's compatibility with existing hardware and configurations, identifies potential bugs or regressions, and assesses its stability under simulated network loads. By proactively uncovering issues in a controlled setting, organizations significantly mitigate the risk of network-wide outages or performance degradation in the production environment.
- ✗
Notify all users of the planned outage
Why it's wrong here
Notifying all users of a planned outage is a crucial communication step within a change management process, but it is premature to do so as the *first* action. Such notifications should only be issued once the technical feasibility and safety of the firmware upgrade have been confirmed through lab testing and formal change approval. Announcing an outage before these validations are complete risks causing unnecessary disruption or requiring multiple rescheduling notices if issues are discovered.
When this WOULD be correct
A network administrator is about to perform a scheduled maintenance that will cause a service interruption. The change has already been approved and tested. The administrator should notify all users of the planned outage to set expectations and minimize disruption.
- ✗
Create a backup of the current switch configuration
Why it's wrong here
While creating a backup of the current switch configuration is an essential preparatory step for any upgrade, it does not address the fundamental risk of the new firmware itself being incompatible or unstable. A configuration backup allows for rollback to a previous state if the *settings* are corrupted, but it cannot recover a device that is bricked or rendered inoperable by faulty firmware code. Therefore, validating the firmware's integrity through testing must precede relying solely on configuration backups.
When this WOULD be correct
A network administrator is about to apply a configuration change to a router. Which step should be performed immediately before making the change to ensure rollback capability?
- ✗
Submit a change request for approval
Why it's wrong here
Submitting a change request for approval is a vital administrative step to formalize and schedule the upgrade, but it should follow initial technical validation. Requesting approval for a critical firmware upgrade without first testing it in a lab environment means the change board would be approving an unverified and potentially risky procedure. The technical team must first ensure the proposed change is safe and viable before seeking formal organizational endorsement.
When this WOULD be correct
In a scenario where the question asks: 'A network administrator is planning a firmware upgrade on a core switch. Which of the following should the administrator do FIRST in the overall change management process?' Then submitting a change request for approval would be the correct first step.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The N10-009 exam frequently reuses these exact scenarios with slightly different constraints.

✗Notify all users of the planned outageWrong answer — click to see why▾
Why this is wrong here
Notifying users of a planned outage is important but should occur after the change has been approved and before implementation; it is not the first step before making the change.
★ When this WOULD be the correct answer
A network administrator is about to perform a scheduled maintenance that will cause a service interruption. The change has already been approved and tested. The administrator should notify all users of the planned outage to set expectations and minimize disruption.
Why candidates choose this
Candidates may think that communication is the most critical initial step, overlooking the need for testing and change management processes first.
✗Create a backup of the current switch configurationWrong answer — click to see why▾
Why this is wrong here
Creating a backup of the current configuration is important but should be done after testing the firmware in a lab, as the first step is to ensure the firmware works correctly before any changes to the production switch.
★ When this WOULD be the correct answer
A network administrator is about to apply a configuration change to a router. Which step should be performed immediately before making the change to ensure rollback capability?
Why candidates choose this
Candidates often confuse the order of operations, thinking that backing up the configuration is the very first step, but testing the firmware in a lab is prioritized to prevent potential issues from untested firmware.
✗Submit a change request for approvalWrong answer — click to see why▾
Why this is wrong here
Submitting a change request for approval is important but should occur before the maintenance window, not as the first step immediately before making the change. The first step before performing the upgrade itself is to test the firmware in a lab to ensure it works correctly.
★ When this WOULD be the correct answer
In a scenario where the question asks: 'A network administrator is planning a firmware upgrade on a core switch. Which of the following should the administrator do FIRST in the overall change management process?' Then submitting a change request for approval would be the correct first step.
Why candidates choose this
Candidates may confuse the order of operations in change management, thinking that formal approval must always precede any technical steps, even when the question specifically asks about actions immediately before the upgrade.
