CompTIA Security+ (SY0-501) — Question 355

A company is executing a strategy to encrypt and sign all proprietary data in transit. The company recently deployed PKI services to support this strategy.
Which of the following protocols supports the strategy and employs certificates generated by the PKI? (Choose three.)

Answer options

• A. S/MIME
• B. TLS
• C. HTTP-Digest
• D. SAML
• E. SIP
• F. IPSec
• G. Kerberos

Correct answer: A, B, C

Explanation

The correct answers, A (S/MIME), B (TLS), and C (HTTP-Digest), all support encryption and can utilize PKI-generated certificates for secure data transmission. Options D (SAML), E (SIP), F (IPSec), and G (Kerberos) either do not primarily focus on encryption in transit or do not directly use PKI certificates in the same way.
