CompTIA Network+ (N10-007) — Question 289

A network technician notices that switches of the same model have different commands and security features while administering them. Which of the following hardening techniques should the technician perform on a regular schedule to ensure all switches have the same features and security functionality?

Answer options

• A. Change the default credentials.
• B. Verify the firmware file hash.
• C. Disable unused switchports.
• D. Apply patches and updates.

Correct answer: D

Explanation

Applying patches and updates (answer D) is essential for ensuring that all switches operate with the latest security features and fixes. Changing default credentials (A) and disabling unused switchports (C) are important practices but do not address the differences in commands and features. Verifying the firmware file hash (B) is a good security measure, but it does not ensure that all switches are updated to the same firmware version.
