CompTIA Security+ (SY0-401) — Question 35

Which of the following controls can be used to prevent the disclosure of sensitive information stored on a mobile devices removable media in the event that the device is lost or stolen?

Answer options

• A. Hashing
• B. Screen locks
• C. Device password
• D. Encryption

Correct answer: D

Explanation

Encryption is the correct answer because it encodes the data, making it unreadable without the proper decryption key, thus protecting sensitive information. While hashing, screen locks, and device passwords help with security, they do not directly prevent unauthorized access to data on removable media if the device is lost or stolen.
