Which Subject Alternate Name must be added to the certificate to allow Jabber Mobile and Remote Access clients to log in successfully?

A. FQDN of the Expressway-C, “expc01.example.local”

B. registration domain, “example.com” or “collab-edge.example.com”

C. Cisco UCM cluster FQDN, “cucmcluster.example.local”

D. FQDN of the Expressway-E, “expe01.example.com”
