Should a computer certificate's CN be just the computer name or the fully qualified domain name?

When using the Certificate snap-in to request a custom certificate, should the CN of the Subject Name be just the computer's hostname or it's FQDN?

For example, a domain-joined computer called workstation1 in the office.local domain - should CN=workstation1 or CN=workstation1.office.local ?

Subject field (or CN attribute) is deprecated by RFC 2818. Instead, all relevant names must be specified in Subject Alternative Names (SAN) certificate extension. You can populate this extension under Subject field editor in certificate request manager.
