The correct answer is to back up the configuration files of all switches, because this task directly supports switch configuration backup disaster recovery by ensuring a replacement device can be brought online with the exact operational settings. Without a recent backup, a new switch ships with factory defaults, requiring manual reconfiguration that extends downtime and risks human error. On the CompTIA Network+ N10-009 exam, this concept tests your understanding of network operations best practices, often appearing in scenario-based questions where a failed switch must be swapped quickly. A common trap is focusing on hardware spares or redundant links instead of the configuration data itself—remember, even a perfect hardware replacement is useless without its software blueprint. Memory tip: think of it as “config first, hardware second”—the backup is the true lifeline for minimizing downtime on replacement.
N10-009 Network Operations Practice Question
This N10-009 practice question tests your understanding of network operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 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?
Why wrong: Firmware upgrades are important for security and features but do not directly help recover from a failure in terms of configuration restoration.
B
Back up the configuration files of all switches
Regular configuration backups allow the administrator to quickly restore the settings to a replacement switch.
C
Monitor the switch's CPU utilization
Why wrong: Monitoring performance helps identify issues but does not prepare for failure recovery.
D
Create a network performance baseline
Why wrong: Baselines help detect anomalies but do not assist in restoring configuration after a failure.
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
Configuration backups are typically stored as text files (e.g., startup-config or running-config on Cisco IOS) and can be exported via TFTP, FTP, SCP, or a network management protocol like SNMP. In a real-world scenario, an administrator might automate backups using a cron job that runs 'copy running-config tftp' daily, ensuring the backup is always current. Without this, a replacement switch would require manual re-entry of VLANs, spanning-tree parameters, port security, and routing protocols, which could take hours and introduce misconfigurations.

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 practitioner preparing for the N10-009 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
