CompTIA Security+ (SY0-701) — Question 546

A systems administrator needs to encrypt all data on employee laptops. Which of the following encryption levels should be implemented?

Answer options

• A. Volume
• B. Partition
• C. Full disk
• D. File

Correct answer: C

Explanation

Full disk encryption is the correct choice because it secures all data on the laptop's hard drive, making it inaccessible without proper authentication. Volume and partition encryption only protect specific sections rather than the entire system, while file encryption only secures individual files, leaving the rest of the data vulnerable.
