New Cisco 400-051 Exam Dumps Collection (Question 14 - Question 23)

Question No: 14

Which two SCCP call signaling messages are initiated by Cisco Unified Communications Manager to an lP phone? (Choose two.)

A. SoftKeyEvent

B. CloseReceiveChannelAck

C. CallState

D. KeypadButton

E. OpenReceiveChannel

F. Offhook

Answer: C, E

Explanation:

Upon receiving anOpenReceiveChannelmessage, the lP phone selects the UDP port number it wants to use to receive RTP packets and reports this information to call manager.

With the SCCP protocol architecture, the majority of the H.323 processing power resides in an H.323 proxy - the Cisco CallManager. The end stations (lP phones) run the Skinny client, which consumes less processing overhead. The client communicates with CallManager using connection-oriented (TCP/lP-based) communication to establish a call with another H.323-compliant end station. Once Cisco CallManager has established the call, the two H.323 end stations use connectionless (UDP/lP-based) communication for audio transmissions.



Question No: 15

Refer to the exhibit.

A customer has two Cisco Unified Communication manager 9.X clusters that serve the same location. An engineer has attempted to set up Enhanced Location call admission control so that any call within a site between phones on the two clusters do not decrement the available bandwidth to and from that site. However, the real time monitoring tool currently shows bandwidth being used from the site to Hub_none. When a call is placed between phones at the site, which action must be taken to correct this situation?

A. The link between clusters must be a type of inter-cluster trunk instead of a sip trunk.

B. The hub_none location must have a link configuration to the phantom location.

C. The device pool names must match between clusters.

D. The Hub_none location must have a link configured to the shadow location.

E. The SlP trunks should be changed to use the shadow location.

Answer: E



Question No: 16

Refer to the exhibit.

When enabling Group and Persistent Chat in an lM&P server, the administrator encountered the problem shown. Which two solutions resolve the issue? (Choose two)

A. Configure the external database to listen in the correct port.

B. Restart the Cisco Route Datastore service in the lm&P server.

C. Make sure the group chat system administrator has access.

D. Configure a new host under Group Chat Server Alias.

E. Fix the user permissions on the external database.

Answer: A, E



Question No: 17

Which two mechanisms does Cisco EnergyWise use for neighbor discovery? (Choose two.)

A. multicast

B. LLDP-MED

C. UDP broadcast

D. Cisco Discovery Protocol

E. TCP

Answer: C, D

Explanation:

Cisco EnergyWise Neighbor Discovery Process

The Cisco EnergyWise neighbor discovery process is the mechanism by which domain members discover each other and populate their Cisco EnergyWise neighbor tables. Cisco EnergyWise queries can subsequently be distributed to all domain members using the neighbor relationships to monitor and control the power usage of devices within a domain. Cisco EnergyWise domain members automatically discover their neighbors through one of two mechanisms:

Cisco EnergyWise UDP broadcast packet

Cisco EnergyWise CDP packets

UDP broadcast packets are automatically sent out switch ports which support Cisco EnergyWise, regardless of whether the interfaces are configured with the no energywise interface-level command. CDP packets are sent when CDP is configured for the switch ports.
