Cisco 400-051 Online Questions & Answers

• Question 451:

  Refer to the exhibit.

  

  Which three events happen when Alice calls [email protected] and the URI lookup policy on the Cisco Unified CM server has been set to case insensitive? (Choose three)

  A. The RTP server routes the call to [email protected] because remote URIs have priority
  B. The RTP sever looks up to see if [email protected] is associated to a local number
  C. The San Jose server calls [email protected] upon receiving the invite request
  D. The San Jose server provide carol's directory URI using ILS exchange
  E. The RTP server sends the call to [email protected] because it has priority
  F. The RTP server drops the call because it has two identical matches
  B. The RTP sever looks up to see if [email protected] is associated to a local number
  D. The San Jose server provide carol's directory URI using ILS exchange
  E. The RTP server sends the call to [email protected] because it has priority

• Question 452:

  Which statement about high availability for XMPP federation in Cisco IM and Presence is true?

  A. A maximum of two Cisco IM and Presence nodes can be enabled for XMPP federation.
  B. Cisco IM and Presence load balances outbound requests across all nodes that are enabled for XMPP federation.
  C. Cisco IM and Presence load balances outbound requests across both nodes that are enabled for XMPP federation in a subcluster.
  D. The XMPP federation-enabled nodes should have different priorities and weights on the published DNS SRV for proper inbound request node selection.
  E. A single DNS SRV record that resolves to an XMPP federation-enabled node must be published on a public DNS server for inbound request routing.
  B. Cisco IM and Presence load balances outbound requests across all nodes that are enabled for XMPP federation.

  ---

  High availability for XMPP federation differs from the high availability model for other IM and Presence Service features because it is not tied to the two node sub-cluster model. To provide high availability for XMPP federation, you must enable two or more IM and Presence Service nodes in your cluster for XMPP federation; having multiple nodes enabled for XMPP federation not only adds scale but it also provides redundancy in the event that any node fails.

• Question 453:

  Refer to the exhibit.

  

  In this high-availability Cisco IM and Presence deployment with three subclusters, the first user is assigned to server 1A; the second user is assigned to server 2A; and the third user is assigned to server 3A. Assume that the Cisco IM and Presence is set to Active/Standby mode, to which server should the fourth user be assigned?

  A. 1A
  B. 3B
  C. 1B
  D. 2A
  E. 3A
  A. 1A

  ---

  This deployment model provides the same level of redundancy and high availability as outlined in the "Balanced Redundant High-Availability Deployment" section in this chapter. The only difference is that users are not deployed in a balanced fashion, but rather all reside on the primary server in the subcluster, and the backup server is there as a standby option if a node failure occurs.

  Which two software components are mandatory in a single combined Cisco Meeting Server (CMS) deployment? (Choose two.)

  A. Call Bridge
  B. Streamer
  C. XMPP Server
  D. TURN Server
  E. Database
  F. Recorder
  G. Web Bridge
  A. Call Bridge
  F. Recorder

• Question 455:

  Company ABC has implemented Cisco Meeting Server (CMS) WebRTC feature using CMS Single Combined deployment model. When testing this implementation, they found that users can login using WebRTC but are unable to join a Space meeting and the "Join Call" option for guests is not available. What is the root cause of this issue?

  A. CMS Webbridge is not able to connect to XMPP component
  B. TURN media ports are blocked between CMS Webbridge and User PC
  C. CMS Webbridge http-redirect configuration is not enabled
  D. CMS Webbridge does not trust Callbridge certificate
  E. CMS Callbridge cannot connect to XMPP component
  D. CMS Webbridge does not trust Callbridge certificate

• Question 456:

  Which three Cisco Unified CM features are affected by Application Dial Rules? (Choose three.)

  A. Unified Mobility
  B. Manager Auto-Attendant
  C. Device Mobility
  D. Manager Assistant
  E. Web Dialer
  F. Extension Mobility
  A. Unified Mobility
  D. Manager Assistant
  E. Web Dialer

• Question 457:

  Which statement about accessing secure Cisco Unity Connection voice messages in an Exchange mailbox in a Single Inbox deployment is true?

  A. Users can listen to a secure voice message if they use the Outlook email client.
  B. Users can listen to a secure voice message if they use the Outlook email client with the ViewMail add-in.
  C. Users can listen to a secure voice message with email clients other than Outlook if they have installed the ViewMail add-in.
  D. Users cannot listen to a secure message in Exchange because it is not supported in Single Inbox.
  E. Secure voice messages are stored on the Cisco Unity Connection server and the Exchange server.
  B. Users can listen to a secure voice message if they use the Outlook email client with the ViewMail add-in.

  ---

  Users can listen to a secure voice message if they use the Outlook email client with the ViewMail add-in. Because in this integration Outlook integrates with unity as secresmapclient.

• Question 458:

  Which three options are Interior device types in Cisco Unified Communications Manager logical partitioning policies? (Choose three.)

  A. MGCP gateway with FXO ports
  B. SIP IP phones
  C. media termination points
  D. MGCP gateway with FXS ports
  E. MGCP gateway with Q.SIG PRI
  F. SIP trunk to Cisco Unity Connection
  B. SIP IP phones
  D. MGCP gateway with FXS ports
  F. SIP trunk to Cisco Unity Connection

• Question 459:

  Refer to the exhibit.
