Question No: 14

Which procedure uses H.225 messages to exchange H.245 Master-Salve Determination information?

A. H.323 Fast Connect

B. H.245 tunneling

C. H.225 tunneling

D. H.323 early media

E. H.245 terminal capability set

Answer: B

Explanation:

The H.245 protocol is a media control protocol that is a part of H.323 protocol suite. The H.245 protocol is used primarily to negotiate master-slave relationship between communicating endpoints. These endpoints exchange terminal capabilities and logical channel manipulations (open, close, modify).The H.245 messages can be encapsulated and carried between H.225 controlled endpoints within H.225 messages. This way of "piggy-backing" an H.245 message to H.225 message is referred to as H245 Tunneling. The H.245 Tunneling method is optional and negotiable between communicating H.323 endpoints. lf both endpoints support this option, usually the H.245 Media Controlled messages are exchanged via the Tunneling method.

Question No: 15

Which two clock rates does Performance Monitor use to calculate RTP jitter values? (Choose two.)

C. PCMA (G.711 A-law) , 16000 Hz

D. H.263 , 90,000 Hz

E. H.263 , 64,000 Hz

Answer: A, D

Question No: 16

An outbound call is in progress through a Cisco Unified Border Element using G729r8 codec. And it is dropped after 60 minutes. Root cause analysis revealed that lTSP signaled a codec change to G711u. Which two Cisco Unified Border

Element configuration changes will prevent this problem from happening again? (Choose two)

A. Configure the voice-class sip midcall-signaling block command on the outbound dial peer.

B. Configure the midcall-signaling preserve-codec under voice service voip.

C. Configure the voice class-codec command with G711u and G729r8 codecs on the outbound dial peer.

D. Configure the voice-class sip midcall-signaling preserve-codec command on the outbound dial peer.

E. Configure the midcall-signaling preserve-codec command under each outbound lTSP dial peer.

F. Configure the midcall-signaling passthru media-change command under voice service voip.

Answer: A, D

Question No: 17

Question No: 19

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.
