CompTIA Network+ (N10-007) — Question 648

A critical vulnerability is discovered on a network device. The vendor states it has already patched this vulnerability in its current release. Which of the following actions should an administrator take?

Answer options

• A. Change the default password
• B. Use a firewall in front of the device.
• C. Update the firmware.
• D. Upgrade the configuration.

Correct answer: C

Explanation

The correct action is to update the firmware because this will apply the patch that addresses the critical vulnerability. Changing the default password and using a firewall do not directly resolve the security flaw, and upgrading the configuration does not ensure that the device is protected against the known vulnerability.
