N10-009 Network Operations Practice Question
A network administrator needs to ensure that in the event of a switch failure, the switch can be replaced and brought online with minimal downtime. Which of the following tasks should the administrator perform regularly?
⚠ Common exam trap
CompTIA often tests the distinction between proactive maintenance tasks (like firmware upgrades or monitoring) and disaster recovery tasks (like configuration backups), leading candidates to choose firmware upgrades because they associate 'minimizing downtime' with keeping software current, when in fact the backup directly enables rapid replacement.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Back up the configuration files of all switches
Regularly backing up the configuration files of all switches ensures that when a failed switch is replaced, the exact configuration can be restored quickly, minimizing downtime. This is a core best practice in network operations because a replacement switch typically ships with factory defaults and requires the original configuration to resume normal operations. Without a recent backup, the administrator would have to reconfigure the switch manually, leading to extended outage and potential human error.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Perform a firmware upgrade on all switches
Why it's wrong here
Firmware upgrades update the operating system of the switch, providing bug fixes, security patches, and new features. While crucial for maintaining a healthy network and preventing certain types of failures, a firmware upgrade itself does not create a mechanism to restore a switch's specific configuration settings (VLANs, port settings, routing protocols) onto a replacement device after a hardware failure. It's a proactive maintenance task, not a reactive recovery strategy for configuration.
When this WOULD be correct
A question asking 'Which task ensures switches have the latest security patches and feature updates?' would make firmware upgrades the correct answer.
- ✓
Back up the configuration files of all switches
Why this is correct
Backing up configuration files involves saving the operational settings, such as VLAN assignments, port security, routing protocols, and access control lists, from the switch's NVRAM to an external server (e.g., TFTP, SCP). In the event of a hardware failure, these saved configurations can be rapidly deployed onto a new or repaired switch, minimizing downtime and ensuring the network segment returns to its intended operational state without manual reconfiguration. This is a direct and efficient method for disaster recovery concerning switch settings.
- ✗
Monitor the switch's CPU utilization
Why it's wrong here
Monitoring a switch's CPU utilization is a critical aspect of proactive network management, as unusually high utilization can signal issues like broadcast storms, misconfigurations, or malicious activity. However, this monitoring provides real-time operational data and alerts, not a recovery plan for a hardware failure. It does not store the switch's configuration and therefore offers no direct means to restore settings onto a replacement device following a catastrophic failure.
When this WOULD be correct
A question asking 'Which task helps identify potential switch overload before it causes network issues?' would make monitoring CPU utilization correct, as it detects high usage that could lead to performance degradation.
- ✗
Create a network performance baseline
Why it's wrong here
A network performance baseline establishes a normal operational profile for metrics like throughput, latency, and error rates over time. While invaluable for identifying deviations that might indicate emerging problems or performance degradation, a baseline is purely a diagnostic tool. It provides no mechanism or data to restore the specific configuration settings of a failed switch; it only helps understand what "normal" looks like, not how to rebuild it from a configuration perspective.
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.

✗Perform a firmware upgrade on all switchesWrong answer — click to see why▾
Why this is wrong here
Performing a firmware upgrade does not directly address the goal of restoring a failed switch with minimal downtime; it is a proactive maintenance task unrelated to rapid replacement.
★ When this WOULD be the correct answer
A question asking 'Which task ensures switches have the latest security patches and feature updates?' would make firmware upgrades the correct answer.
Why candidates choose this
Candidates may think keeping firmware current is essential for reliability, but it does not speed up recovery after a failure.
✗Monitor the switch's CPU utilizationWrong answer — click to see why▾
Why this is wrong here
Monitoring CPU utilization helps identify performance issues but does not prepare for switch replacement or reduce downtime after a failure; it is a proactive monitoring task, not a recovery task.
★ When this WOULD be the correct answer
A question asking 'Which task helps identify potential switch overload before it causes network issues?' would make monitoring CPU utilization correct, as it detects high usage that could lead to performance degradation.
Why candidates choose this
Candidates may think that monitoring CPU utilization is part of regular maintenance that indirectly aids recovery, but they overlook that the question specifically focuses on minimizing downtime after a failure, not preventing it.

Key term
Switch
A switch is a networking device that connects devices on a local area network and uses MAC addresses to forward data only to the intended recipient.
Key term
Backup
A backup is a copy of computer data taken and stored separately so that the original data can be restored if it is lost, damaged, or corrupted.
