Implementing Cisco Network Security (IINS, legacy) — Question 74

What is an advantage of implementing a Trusted Platform Module for disk encryption?

Answer options

• A. It supports a more complex encryption algorithm than other disk-encryption technologies
• B. It provides hardware authentication
• C. It can protect against single points of failure

Correct answer:

Explanation

The correct answer is B, as a Trusted Platform Module (TPM) offers hardware authentication, ensuring that the system's integrity is verified before allowing access to encrypted data. Option A is incorrect because the complexity of the encryption algorithm is not a defining feature of TPM. Option C is also wrong, as TPM does not inherently protect against single points of failure; its primary function is related to security and authentication.
