CompTIA Network+ (N10-007) — Question 601

A network technician wants to ensure the backup configuration files for the network devices are not being altered after they are stored. Which of the following tasks should the network technician perform to achieve this goal?

Answer options

• A. Compute the checksum of the backup file and document it separately.
• B. Store the backup files on a thumb drive and keep it in a desk drawer.
• C. Encrypt the drive the files are stored on using AES-256.
• D. Upload the backup files to a cloud storage service.

Correct answer: A

Explanation

Calculating and documenting the checksum of the backup file allows the technician to verify the integrity of the file later on, ensuring it hasn't been modified. Storing files on a thumb drive or in cloud storage does not inherently prevent alterations, and while encryption protects data confidentiality, it does not verify file integrity.
