CompTIA Network+ (N10-007) — Question 578

A recent vulnerability was discovered in the code a company is running on its network devices. The vendor has released a security patch to address the vulnerability. To ensure an unaltered version of the patch is downloaded, which of the following should the network technician validate before installing the patch?

Answer options

• A. Date the patch was created
• B. Version of the patch
• C. Hash values of the patch
• D. Change log for the patch

Correct answer: C

Explanation

The correct answer is C, as verifying the hash values of the patch ensures that it has not been altered or corrupted during download. The creation date, version, and change log do not guarantee the integrity of the patch, as they do not confirm whether the file itself is unchanged.
