Selected Answer: C
Wildcard Certificates A wildcard certificate is one that contains the wildcard character * in its domain name field. This allows the certificate to be used for any number of subdomains. Not to be confused with subject alternate name (SAN), wildcard certificates can only be used for subdomains where a SAN can be used to specify a completely different domain name. Wildcard certificates are particularly useful for SSL accelerators and load balancers (LB) that provide the outward-facing component of a website.
