CompTIA CASP+ (CAS-004) — Question 292

A systems administrator at a web-hosting provider has been tasked with renewing the public certificates of all customer sites. Which of the following would BEST support multiple domain names while minimizing the amount of certificates needed?

Answer options

• A. OCSP
• B. CRL
• C. SAN
• D. CA

Correct answer: C

Explanation

The correct answer is C, SAN (Subject Alternative Name), which allows a single certificate to secure multiple domain names. Options A (OCSP) and B (CRL) are related to certificate validation and revocation but do not address the need for multiple domains. Option D (CA) refers to Certificate Authority, which issues certificates but does not directly manage multiple domain names under a single certificate.
