CompTIA Security+ (SY0-701) — Question 386

For which of the following reasons would a systems administrator leverage a 3DES hash from an installer file that is posted on a vendor’s website?

Answer options

• A. To test the integrity of the file
• B. To validate the authenticity of the file
• C. To activate the license for the file
• D. To calculate the checksum of the file

Correct answer: A

Explanation

The correct answer is A because a 3DES hash is commonly used to ensure that the file has not been altered or corrupted during download. Options B and D are related but focus on authenticity and checksum calculations, which do not directly pertain to integrity testing. Option C is incorrect as licensing activation does not involve hash verification.
