Question 1 of 30
Consider a Cisco collaboration environment where a two-node Cisco Unified Presence (CUP) cluster is configured as the primary presence and instant messaging server for Cisco Jabber clients. If the primary CUP server node experiences a catastrophic hardware failure, leading to its immediate unavailability, what is the most likely immediate impact on the functionality of Jabber clients connected to the cluster?
Jabber clients will continue to function for presence updates and instant messaging, with the secondary CUP server automatically assuming the active role.
Jabber clients will experience a complete loss of instant messaging and presence functionality until the primary CUP server is restored.
Jabber clients may encounter intermittent delays in call setup due to the reliance on presence information for call routing.
Administrators will need to manually reconfigure Jabber clients to connect to the secondary CUP server to re-establish connectivity.
