CompTIA A+ Core 2 (220-1002) — Question 447

A technician is encrypting the company's laptops using BitLocker, but some of the laptops do not have a built-in TPM.
Which of the following would enable the technician to use BitLocker on these machines?

Answer options

• A. A USB key
• B. A firmware update
• C. A local disk
• D. Two-factor authentication

Correct answer: A

Explanation

Using a USB key allows the technician to store the BitLocker key, which is necessary for encryption on devices without a TPM. A firmware update does not provide the necessary hardware support for BitLocker, while a local disk cannot be used for this purpose. Two-factor authentication is unrelated to the encryption process itself.
