Certified Information Systems Security Professional (CISSP) — Question 240

A security professional needs to find a secure and efficient method of encrypting data on an endpoint. Which solution includes a root key?

Answer options

• A. Bitlocker
• B. Trusted Platform Module (TPM)
• C. Virtual storage array network (VSAN)
• D. Hardware security module (HSM)

Correct answer: B

Explanation

The Trusted Platform Module (TPM) is specifically designed to generate and store cryptographic keys securely, including the root key, which is essential for encryption processes. Bitlocker is an encryption tool but does not specifically mention a root key. Virtual storage array network and Hardware security modules, while related to storage and security, do not inherently provide a root key for encryption purposes.
