CompTIA CASP+ (CAS-004) — Question 183

An organization is looking to establish more robust security measures by implementing PKI. Which of the following should the security analyst implement when considering mutual authentication?

Answer options

• A. Perfect forward secrecy on both endpoints
• B. Shared secret for both endpoints
• C. Public keys on both endpoints
• D. A common public key on each endpoint
• E. A common private key on each endpoint

Correct answer: C

Explanation

The correct choice is C, as mutual authentication in PKI relies on each endpoint having its own public key to verify identities securely. Options A, B, D, and E do not provide the necessary framework for mutual authentication using PKI, as they either focus on shared secrets or common keys, which compromise individual endpoint verification.
