CompTIA A+ Core 2 (220-1102) — Question 237

Which of the following macOS utilities uses AES-128 to encrypt the startup disk?

Answer options

• A. fdisk
• B. Diskpart
• C. Disk Utility
• D. FileVault

Correct answer: D

Explanation

FileVault is the macOS feature specifically designed to encrypt the startup disk using AES-128 encryption. The other options, such as fdisk and Diskpart, are not relevant to macOS encryption, and Disk Utility, while it manages disks, does not directly handle encryption like FileVault does.
