    B. CPL that blocks calls with a destination domain other than example.com on the Expressway-C.

    C. search rules to only route calls with a destination domain of example.com on the Expressway-E

    D. CPL to block calls with a destination URI with 8 or more digits on the Expressway-E

    A. Set calls to unknown IP addresses to direct on the Cisco Expressways, and add a search rule on the Expressway-E

    B. Set calls to unknown IP addresses to indirect on the Cisco Expressways, and add a search rule on the Expressway-E

    C. Use search rules to manage calls to IP addresses, and the direct/indirect setting on the Expressway is used as a fallback only if the search rules do not exist

    D. Set calls to unknown IP addresses to indirect on the Expressway-C and direct on the Expressway-E, and add a search rule on the Expressway-E

  • Question 37:

    Cisco Jabber clients are failing to log in using Mobile and Remote Access. The administrator checked the Jabber problem report logs and saw that connections to the Expressway-E are being refused on TCP port 8443. From a packet capture run on the Jabber client while attempting to log in, there is no response to the TCP SYN packets sent to the Expressway-E by Jabber.

The engineer is advised that the packet capture shows the required packets for the SSH tunnels leaving the Expressway-C but not reaching the Expressway-E. Which firewall configuration must the engineer allow to resolve this issue?

    A. port 2222 from Expressway-E to Expressway-C

    B. port 7001 from Expressway-C to Expressway-E

    C. port 7001 from Expressway-E to Expressway-C

    D. port 2222 from Expressway-C to Expressway-E

  • Question 40:

    Why would a Cisco Jabber contact under Hybrid Messaging Integration be grayed out?

    A. The contact uses Cisco Webex Teams and Jabber and remains as Do not Disturb for 30 minutes.
