  • Question 13:

    An administrator installs a new webserver (server1.example.com ?10.1.1.90) for storing Cisco Jabber update files to the network, but all Mobile and Remote Access registered clients still run the old Jabber software version, and the update fails. Which configuration task on an Expressway server solves the Jabber software update issue?

    A. Add a rule with the URL http://server1.example.com:80/ to the outbound HTTP allow list manually to allow pushing the new software to the clients.

    B. Add a rule with the URL http://server1.example.com:80/ to the inbound HTTP allow list manually to allow access to the new web server.

    C. Add a rule with the server IP address 10.1.1.90 in the URL to the inbound HTTP allow list because server names and FQDNs are not supported.

    D. Run an IM and Presence server discovery process on Expressway-C to add the new web server to the inbound HTTP allow list automatically.

  • Question 14:

    Cisco Expressways are being deployed for Mobile and Remote Access. The Expressway-E internal interface (LAN1) IP is 192.168.100.10/24, and the external interface (LAN2) IP is 172.16.100.10/24. The Expressway-C IP is 192.168.20.10/24. The default gateway for each subnet is the rst useable address. How must the Expressway-E be configured to allow proper routing to the internal and external networks?

    A. IPv4 gateway: 172.16.100.1, and a static route for the 192.168.100.0/24 subnet using LAN1

    B. IPv4 gateway: 192.168.100.1, and a static route for the 192.168.20.0/24 subnet using LAN1

    C. IPv4 gateway: 192.168.100.1, and a static route for the 172.16.100.0/24 subnet using LAN2

    D. IP v4 gateway: 172.16.100.1, and a static route for the 192.168.20.0/24 subnet using LAN1

  • Question 15:

    B. cisco.com on the Expressway-C certificate

    C. Securephone.cisco.com on the Expressway-E certificate

    D. cisco.com on the Expressway-E certificate

    E. Securephone.cisco.com on the Expressway-C certificate

  • Question 16:

    An administrator configures a secure SIP trunk in Cisco UCM to Expressway-C. The SIP trunk fails to become active, and an examination of a packet capture finds that the TLS handshake failed with a "certificate Unknown" error from Cisco UCM. To allow the Cisco UCM to trust the Expressway-C and establish a TLS connection, the administrator will upload the Expressway server certificate to the trust store. To which trust store must the certificate be uploaded?

    A. tomcat-trust

    B. CallManager-trust

    C. TVS-trust

    D. ipsec-trust

    An administrator troubleshoots Cisco Jabber users experiencing issues when trying to log in and notices errors in the Jabber problem report log. The administrator also sees that the Intercluster Sync Agent service is not running on the IMM and Presence server. Why is the Jabber client unable to sign in?

    A. The XmppSDK.dl file is missing from the IM and Presence server

    B. The XMPP stanza is not using the correct ID for the Jabber client.

    C. The XMPP bind failed on the IM and Presence server

    D. The Jabber client refused the XMPP bind connection.

  • Question 20:

    An engineer is supporting an existing Cisco Collaboration deployment that has internal and external home users using the solution without VPN. Business usage also includes B2B calling for voice and video. Suddenly the engineer receives a report that one of the home office users cannot use the Cisco Jabber client, and shortly after, a few more reports come in for the same error. What must the engineer check first to resolve this issue?
