Cisco 400-051 Online Practice Questions and Exam Preparation

Cisco 400-051 Online Questions & Answers

• Question 201:

  Which capability is supported by Cisco Discovery Protocol but not by LLDP-MED?

  A. LAN speed and duplex discovery
  B. Network policy discovery
  C. Location identification discovery
  D. Power discovery
  E. Trust extension
  E. Trust extension

  ---

  Cisco Discovery Protocol provides an additional capability not found in LLDP-MED that allows the switch to extend trust to the phone. In this case, the phone is now trusted to mark the packets received on the PC port accordingly. This feature can be used to off-load the switch because now it does not need to police the information being received from the phone.

• Question 202:

  In Cisco IOS routers, which chipset is the PVDM2-32 DSP hardware based on?

  A. C5441
  B. C549
  C. C5510
  D. C5421
  E. Broadcom 1500
  C. C5510

• Question 203:

  In which call state does the Mobility soft key act as a toggle key to enable or disable Single Number Reach for Cisco Unified Communications Manager Express SCCP IP phones?

  A. idle
  B. seized
  C. alerting
  D. ringing
  E. connected
  A. idle

  ---

  Pressing the Mobility soft key during the idle call state enables the SNR feature. This key is a toggle; pressing it a second time disables SNR.

• Question 204:

  Which statement describes the call recording operation on Cisco Unified Contact Center Express call agents that use Cisco IPPA?

  A. Recording is facilitated via desktop monitoring on supported IP phones.
  B. Automatic recording is supported.
  C. Only G.711 codec is supported.
  D. Only SPAN port monitoring is supported.
  E. Call recording is not supported on Cisco Unified CCX call agents that use Cisco IPPA.
  D. Only SPAN port monitoring is supported.

  ---

  There is no mechanism created as of now to record the call so we first span and record it from packet capture or from third party software.

• Question 205:

  Which two call processing features have a lower priority than the Do Not Disturb settings on a Cisco IP phone? (Choose two.)

  A. park reversion for a locally parked call
  B. hold reversion
  C. intercom
  D. pickup notification
  E. terminating side of a call back
  F. originating side of a call back
  D. pickup notification
  E. terminating side of a call back

  ---

  For the DND Ringer Off option, only visual notification gets presented to the device.

  For the DND Call Reject option, no notification gets presented to the device.

  For the terminating side of the call, Do Not Disturb overrides call back:

  When the phone that terminates the call uses DND Ringer Off, the Callback Available screen will be displayed on the phone after the terminating side goes off hook and on hook.

  When the phone that terminates the call has DND Call Reject enabled but the phone becomes available (goes off hook and on hook), a new screen will be presented to the originating device as " has become available but is on

  DND-R". Callback available notification will be sent only after the terminating side disables DND Call Reject.

• Question 206:

  Which three statements about blended addressing in ILS/URI dialing are true? (Choose three.)

  A. The destination endpoint can use either the directory URI or the directory number for its response; both reach the same destination
  B. Cisco Unified Communications Manager inserts the directory URI and the directory number of the sending party in outgoing responses to SIP invites
  C. Cisco Unified Communications Manager inserts the directory URI and the directory number of the sending party in outgoing SIP invites but not for the responses to SIP invites
  D. The destination endpoint must use the directory URI and the directory number for its response
  E. Cisco Unified Communications Manager inserts the directory URI and the directory number of the sending party in outgoing SIP invites
  F. Cisco Unified Communications Manager inserts the directory URI of the sending party in outgoing SIP invites
  A. The destination endpoint can use either the directory URI or the directory number for its response; both reach the same destination
  B. Cisco Unified Communications Manager inserts the directory URI and the directory number of the sending party in outgoing responses to SIP invites
  F. Cisco Unified Communications Manager inserts the directory URI of the sending party in outgoing SIP invites

• Question 207:

  Which Cisco IM and Presence service is responsible for logging all IM traffic that passes through the IM and Presence server to an external database for IM compliance?

  A. Cisco Presence Engine
  B. Cisco Serviceability Reporter
  C. Cisco Sync Agent
  D. Cisco XCP Connection Manager
  E. Cisco XCP Message Archiver
  E. Cisco XCP Message Archiver

  ---

  The Cisco Unified Presence XCP Message Archiver service supports the IM Compliance feature. The IM Compliance feature logs all messages sent to and from the Cisco Unified Presence server, including point-to-point messages, and messages from adhoc (temporary) and permanent chat rooms for the Chat feature. Messages are logged to an external Cisco-supported database.

• Question 208:

  

  Refer to the exhibit. Company ABC tried to configure Cisco Meeting Server as an Ad-hoc Conferencing resource for Cisco Unified CM but the conference bridge failed to register. Review the exhibits of CMS configuration (webadmin and callbridge) as well the CMS certificates, what is the cause of the registration failure?

  A. Webadmin and Callbridge are listening on same interface `a'
  B. Webadmin is listening on port 444 which is not supported by Unified CM
  C. Webadmin and Callbridge are using same certificate and Key pair
  D. Callbridge Address is not configured
  E. Webadmin is using CMS self-signed certificate
  B. Webadmin is listening on port 444 which is not supported by Unified CM

• Question 209:

  

  Refer to the exhibit. Which URI dial-peer will be selected to route the incoming SIP INVITE received from the ITSP?

  A. voice class uri SIPURI4 sip host ipv4:10.106.77.220 dial peer voice 1 voip session protocol sipv2 incoming uri request SIPURI4
  B. voice class uri SIPURI2 sip host ipv4:10.106.77.220 dial peer voice 4 voip session protocol sipv2 incoming uri request SIPURI2
  C. voice class uri SIPURI2 sip host ipv4:10.106.77.212 dial peer voice 3 voip session protocol sipv2 incoming uri from SIPURI2
  D. voice class uri SIPURI4 sip host ipv4:10.106.77.220 dial peer voice 5 voip session protocol sipv2 incoming uri to SIPURI4
  E. voice class uri SIPURI2 sip host ipv4:10.106.77.220 dial peer voice 2 voip session protocol sipv2 incoming uri via SIPURI2
  D. voice class uri SIPURI4 sip host ipv4:10.106.77.220 dial peer voice 5 voip session protocol sipv2 incoming uri to SIPURI4

• Question 210:

  Which codec complexity mode, when deployed on Cisco IOS routers with DSPs using the C5510 chipset, supports the most G.711 calls per DSP?

  A. Low
  B. Medium
  C. High
  D. Secure
  E. Flex
  E. Flex

  ---

  The flex parameter allows the complexity to automatically adjust to either medium or high complexity depending on the needs of a call. For example, if a call uses the G.711 codec, the C5510 chipset automatically adjusts to the medium-complexity mode. However, if the call uses G.729, the C5510 chipset uses the high complexity mode
