Which of these is the best practice to employ when using certificates between a browser and the Cisco Unified CallManager 5.0 server?

A.
Accept the certificate when the security alert pop-up window appears.

B.
Use SSH exclusively to verify the thumbprint of the certificate and then send the certificate to all web browser users that require access to the server.

C.
Use either SSH or CLI to view the thumbprint of the certificate and then communicate the information to all web browser users so they already have it available when they receive the security alert.

D.
Note the thumbprint of the Cisco Unified CallManager certificates after installation and then communicate the information to all web browser users so they have it available when they receive the security alert.

E.
Install thumbprint readers on the devices that need to connect to the Cisco Unified CallManager servers via HTTPS.
