The key size that you select depends on the level of security that you want to configure and on any
limitations imposed by the CA from which you are obtaining the certificate. The larger the number that
you select, the higher the security level will be for the certificate. Most CAs recommend 2048 for the
key modulus size; however, GoDaddy requires a key modulus size of 2048.

provides the common name (CN), which is the FQDN of the Cisco Mobility Advantage server
or Cisco Unified Presence server, respectively.
