CompTIA ITF+ (FC0-U71) — Question 40

Which of the following makes a file readable only by select users who possess a key?

Answer options

• A. Hidden folders
• B. File permissions
• C. Compression
• D. Encryption

Correct answer: D

Explanation

The correct answer is D, Encryption, as it secures a file so that only individuals with the appropriate decryption key can access it. Options A (Hidden folders) and B (File permissions) relate to visibility and access control but do not restrict access in the same way as encryption. Option C (Compression) is irrelevant as it merely reduces file size without affecting accessibility.
