Use the exhibits below to answer the question.
What two issues could be causing the Cisco Jabber failure shown in the exhibit? (Choose
two)

A.
Incorrect username and password

B.
IM & Presence server is down

C.
User is not associated with the device

D.
IP or DNS name resolution issue

E.
CSF Device is not registered.

F.
IP Phone DN not associated with the user

The error message shown in Jabber is “Cannot communicate with the server” which points us
to a connectivity issue with IP/DNS or the server is down. All other answer choices would
result in a login failure, not communication error.
