CompTIA A+ Core 1 (220-1001) — Question 131

A company is concerned about the security of sensitive data on a laptop a user frequently takes off-site.
Which of the following enables hardware encryption to secure user data?

Answer options

• A. BIOS password
• B. Hibernation mode
• C. Trusted Platform Module
• D. Screen-saver lock

Correct answer: C

Explanation

The Trusted Platform Module (TPM) is a dedicated microcontroller designed to secure hardware by integrating cryptographic keys into devices, making it the correct choice for hardware encryption. A BIOS password secures the BIOS but does not encrypt data, while hibernation mode saves data to disk without encryption, and a screen-saver lock merely prevents unauthorized access without securing data.
