CompTIA Security+ (SY0-501) — Question 891
An administrator needs to protect five websites with SSL certificates. Three of the websites have different domain names, and two of the websites share the domain name but have different subdomain prefixes. Which of the following SSL certificates should the administrator purchase to protect all the websites and be able to administer them easily at a later time?
Answer options
- A. One SAN certificate
- B. One Unified Communications Certificate and one wildcard certificate
- C. One wildcard certificate and two standard certificates
- D. Five standard certificates
Correct answer: A
Explanation
The correct option is A, as a SAN (Subject Alternative Name) certificate can cover multiple domains and subdomains under a single certificate, simplifying management. Options B and C suggest a combination of different certificate types that would complicate administration, while option D would require managing five separate certificates, which is less efficient.
