CompTIA A+ Core 2 (220-1102) — Question 609

A Windows user wants a filesystem that protects confidential data from attackers who have physical access to the system. Which of the following should the user choose?

Answer options

• A. ext
• B. APFS
• C. FAT
• D. EFS

Correct answer: D

Explanation

EFS (Encrypting File System) is specifically designed to encrypt files on Windows systems, providing protection for confidential data against unauthorized access, even with physical access to the device. The other options, such as ext, APFS, and FAT, do not offer built-in encryption features that secure data in this manner.
