Cisco 300-820 Online Questions & Answers

  • Question 1:

    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

  • Question 2:

    An administrator is enabling Mobile and Remote Access login for the Cisco UCM registration domain cisco.com. Phones are registered with a Cisco UCM phone security profile name of securephone.cisco.com. Which two subject alternative names must be configured? (Choose two.)

    A. Securephone.cisco.com on the CallManager certificate
    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 3:

    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 4:

    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 5:

    What is the first step to restoring an Expressway cluster from a backup?

    A. use the backup that is specific to each Expressway peer in the cluster
    B. upgrade each Expressway peer to the latest Expressway software
    C. remove each Expressway peer from the cluster
    D. add all the Expressway peers to the cluster

  • Question 6:

    An engineer must configure Mobile and Remote Access. One of the requirements is to expect Cisco Jabber users to enter username@cisco.com as the login userid. Which DNS record must the engineer modify to start implementing this requirement?

    A. _cuplogin._tcp.cisco.com
    B. _collab-edge._tls.cisco.com
    C. _cisco-uds._tls.cisco.com
    D. _cisco-uds._tcp.cisco.com

  • Question 7:

    Refer to the exhibit.

    When Expressway-E routes a call with URI 4040@uclab.local to a DNS zone, which DNS server does the Expressway query for the SIP SRV records?

    A. 10.20.20.20
    B. 10.10.10.10
    C. 10.40.40.40
    D. 10.30.30.30

  • Question 8:

    An administrator is configuring a new Cisco Webex Hybrid Message Service deployment, and the Expressway-C Message Connector is successfully registered in the Control Hub. After the server information of the IM and Presence server is

    added to the Expressway-C, an error "Connectivity to IM and Presence AXL Service could not be established" is displayed in the Control Hub. The Cisco AXL Web Service is enabled on the IM and Presence Service publisher, and the main

    administrator account enabled for AXL API permission is being used.

    Which configuration change must be made to resolve this error?

    A. Enable the Cisco AXL Web Service on the Control Hub
    B. Enable the Cisco AXL Web Service on the Expressway-C Message Connector
    C. Enable an End User account for AXL.API permissions on the IM and Presence Service publisher
    D. Enable a second administrator account for AXL API permissions on the IM and Presence Service publisher

  • Question 9:

    An employee has recently left an organization and a manager suspects that this employee may have made changes to the system that no one is aware of. Mobile and Remote Access registration is not working. Internal communications appear to be working, but no external system is able to register or call anywhere. While investigating this problem, it is discovered that no internal systems are able to call externally either. What is the TraversalZone missing that is causing this issue?

    A. SIP trunk to the DefaultZone
    B. route pattern to the DefaultZone
    C. link to the DefaultZone
    D. pipe to the DefaultZone

  • Question 10:

    Refer to the exhibit.

    A Cisco Webex device on an enterprise network has identified the given STUN round-trip delays in milliseconds to the enterprise Video Mesh clusters and two Webex Cloud Media clusters during the call setup. Which correct sequence of clusters is the client connecting to?

    A. US West Coast WCMC. If US West Cost WCMC is full, then Europe WCMC because clients select clusters in the order of SRT delays.
    B. DC Europe. If DC Europe is full, DC APAC because clients select on-premises clusters in the order of SRT delays before using cloud resources,
    C. DC Europe. If DC Europe is full, US West Coast WCMC because clients select resources in the order of SRT delays but ignore SRTs greater than 250 ms
    D. US West Coast WCMC. Clients continuously monitor DC US cluster and reconnect when DC US are available to save bandwidth.
