Question
An engineer is notified that the Apple Push Notification Service fails to work when an instant message is sent to a remote worker by using Mobile and Remote Access for Cisco Jabber registration in an environment that uses Cisco UCM. Apple Push Notification Service is a newly deployed feature that has never worked for Mobile and Remote Access users, but it works for on- premises registered users. Which two actions must be performed to allow notifications to be sent to the remote workers? (Choose two.)
Options
- ARestart all the Cisco Expressway-E nodes in the cluster.
- BRestart all the Cisco Expressway-C nodes in the cluster.
- CRefresh the Cisco UCM Administration servers from Cisco Expressway-E and restart all the nodes
- DRefresh the Cisco UCM Administration servers from Cisco Expressway-C and restart all the nodes
- ERestart the Cisco Tomcat service on all the Cisco UCM servers in the cluster.

Explanation
APNs works for on-premises users but fails for MRA (Mobile and Remote Access) users, indicating the issue is specific to the Expressway-C path. For APNs to function over MRA, Expressway-C must be aware of the UCM servers to properly forward push notification traffic. The two required steps are: (D) Refresh the Cisco UCM Administration servers from Expressway-C so it has the current UCM node information, then restart the Expressway-C nodes; and (B) Restart all Expressway-C nodes to apply the updated configuration and re-establish the APNs notification path. Expressway-E handles external traffic but APNs routing for MRA is managed through Expressway-C's relationship with UCM.
