CompTIA Security+ (SY0-501) — Question 89

A security administrator is trying to encrypt communication. For which of the following reasons should administrator take advantage of the Subject Alternative
Name (SAM) attribute of a certificate?

Answer options

• A. It can protect multiple domains
• B. It provides extended site validation
• C. It does not require a trusted certificate authority
• D. It protects unlimited subdomains

Correct answer: B

Explanation

The correct answer is B because the Subject Alternative Name attribute allows for extended validation of multiple sites, ensuring a higher level of verification. Options A, C, and D are incorrect as they either misrepresent the primary function of the SAN attribute or provide misleading information about certificate authority requirements.
