CompTIA Security+ (SY0-501) — Question 477

A technician, who is managing a secure B2B connection, noticed the connection broke last night. All networking equipment and media are functioning as expected, which leads the technician to question certain PKI components. Which of the following should the technician use to validate this assumption? (Choose two.)

Answer options

• A. PEM
• B. CER
• C. SCEP
• D. CRL
• E. OCSP
• F. PFX

Correct answer: D, E

Explanation

The correct answers, CRL and OCSP, are used to check the revocation status of certificates in a PKI environment. While PEM, CER, SCEP, and PFX are related to certificate formats and management, they do not directly address the validity of certificates and their revocation status, which is crucial in diagnosing the connection issue.
