• Question 5:

  Which option describes how you can show the same contacts in your Jabber for Windows on-premise client as you do on the corporate directory of your IP phone?

  A. Switch your Jabber client to use UDS instead of EDI.
  B. Switch your Jabber client to use EDI instead of UDS.
  C. Update your IMandP server to sync off of the same LDAP directory as your Cisco Unified Communications Manager.
  D. Add Jabber to your inbound/outbound firewall rules on your PC.
  E. Jabber can only pull directly from LDAP and cannot directly search the Cisco Unified Communications Manager user database.
  A. Switch your Jabber client to use UDS instead of EDI.

  ---

  explanation:

  LDAP contact resolution -- The client cannot use LDAP for contact resolution when outside of the corporate firewall. Instead, the client must use UDS for contact resolution. When users are inside the corporate firewall, the client can use either UDS or LDAP for contact resolution. If you deploy LDAP within the corporate firewall, Cisco recommends that you synchronize your LDAP directory server with Cisco Unified Communications Manager to allow the client to connect with UDS when users are outside the corporate firewall.

• Question 8:

  Two Jabber clients are unable to pass instant messages between each other. What is the appropriate next step?

  A. Review XCP router logs.
  B. Open port 5060 on the firewalls between the PCs and the IMandP servers.
  C. Review SIP proxy logs.
  D. Review Help > Show Connection Status in each Jabber client, and pull logs as necessary.
  A. Review XCP router logs.

  ---

  explanation:

  The XCP Router is the core communication functionality on the Cisco Unified Presence server. It provides XMPP-based routing functionality on Cisco Unified Presence; it routes XMPP data to the other active XCP services on Cisco Unified Presence, and it accesses SDNS to allow the system to route XMPP data to Cisco Unified Presence users. The XCP router manages XMPP sessions for users, and routes XMPP messages to and from these sessions.

• Question 9:

  Which three services must be stopped to change the IM and Presence service default domain setting of DOMAIN.NOT.SET? (Choose three.)

  A. Cisco XCP Router
  B. Cisco Intercluster Sync Agent
  C. Cisco XCP Authentication Service
  D. Cisco SIP Proxy
  E. Cisco Presence Engine
  F. Cisco AXL Web service
  A. Cisco XCP Router
  D. Cisco SIP Proxy
  E. Cisco Presence Engine

  explanation:

  Change the Domain Value

  Follow this procedure if you want to change the domain value (from one valid domain value to another valid IP proxy domain value).

  This procedure is applicable if you have a DNS or non-DNS deployment.

  Procedure

  Step 1 Stop the Cisco SIP Proxy, Presence Engine and XCP Router services on IM and Presence on all nodes in your cluster.

  Step 2 On the publisher node, perform the following steps to configure the new domain value:

  a.

  Select IM and Presence Administration > System > Cluster Topology.

  b.

  In the right pane, select Settings.

  c.

  Configure the Domain Name value with the new domain.

  a.

  Select IM and Presence Administration > System > Service Parameters, and select the Cisco SIP Proxy service.

  b.

  Configure the Federation Routing IM and Presence FQDN with the new domain.

  c.

  You will be prompted to confirm these configuration changes. Select OK for both prompts, and then select Save.

  Step 3 On all nodes in the cluster, use this CLI command to set the new domain:

  set network domain

  This CLI command invokes a reboot of the servers.

  Step 4 On all nodes in the cluster, manually start the Cisco Presence Engine and Cisco XCP Router services after the reboot is complete (if required).

  Step 5 Manually regenerate all certificates on each node in the cluster.
