CompTIA Server+ (SK0-005) — Question 217

The management team has mandated the use of data-at-rest encryption for all data. Which of the following forms of encryption best achieves this goal?

Answer options

• A. Drive
• B. Database
• C. Folder
• D. File

Correct answer: A

Explanation

Drive encryption protects all data stored on a hard drive, ensuring that all information is automatically encrypted when written to disk. While database, folder, and file encryption can secure specific sets of data, they do not provide the comprehensive coverage that drive encryption offers for all data-at-rest.
