To have three SSL websites served by a single SSL vServer, using a certificate that covers all domains, which certificate type should be bound?

• A. A wildcard certificate to a single SSL vServer
• B. A wildcard certificate to a content-switching vServer
• C. The certificate of each website to a single SSL vServer
• D. A multiple SAN certificate to a single SSL vServer

Answer: (D)

When you want one SSL vServer to serve multiple domains, you need a certificate that explicitly covers all those domain names. A SAN (Subject Alternative Name) certificate includes several domain names in a single certificate, so the vServer can present one cert that is valid for all three sites regardless of which domain a client requests. This keeps configuration simple and avoids managing separate certificates for each domain on the same vServer.

A wildcard certificate would only cover subdomains under one base domain, so it won’t reliably cover three distinct domains. Using a separate certificate for each site defeats the goal of a single vServer hosting all sites. A content-switching vServer isn’t about the certificate type needed to serve multiple domains from one vServer. Bind the SAN certificate to the SSL vServer to achieve the desired setup.
