How does a configuration baseline help maintain network stability?

It increases the bandwidth of the network

It encrypts all data in transit

It provides a standard to compare against, making it easier to detect unauthorized or unintended changes

It automatically blocks all unauthorized traffic

A network team is planning to upgrade the operating system on all distribution switches. The team wants to ensure that after the upgrade, the switches are configured exactly as they were before, with no unintended changes. Which step is MOST critical to include in the upgrade plan?

Increase the logging level on the switches to capture any configuration changes during the upgrade.

Capture the current configuration baseline and verify it against the post-upgrade configuration.

Upgrade the switches one at a time and hope that the configuration is preserved.

Assign a junior administrator to manually reconfigure the switches after the upgrade.

A network team uses a Git repository to manage configuration files for all network devices. An administrator accidentally commits a configuration change that contains a syntax error. The error is not noticed until several other commits have been made. What is the BEST way to resolve this issue?

Use 'git revert' to create a new commit that undoes the erroneous change, preserving the commit history.

Manually edit the configuration file and commit the corrected version.

Use 'git reset' to remove the erroneous commit and all subsequent commits.

Delete the Git repository and recreate it from the last known good backup.

What is the purpose of auditing network configurations?

To verify that configurations comply with organizational policies and security standards

To replace all network hardware

To increase the speed of the network

To provide a backup of all user data

A network administrator is about to apply a critical security patch to a core router. The change has been approved, but the administrator wants to ensure the router can be restored to its exact pre-change state if the patch causes unexpected issues. Which procedure should the administrator perform BEFORE applying the patch?

Verify that the router's firmware is up to date before proceeding.

Record the router's uptime and CPU usage in the change log.

Capture a packet trace of the router's traffic to document normal behavior.

Save the running configuration to the startup configuration and then back up the startup configuration to a secure server.
