A. 183 Session in Progress

B. 199 Early Dialog Terminated

C. 200 OK

D. 180 Ringing

Q14. Which statement describes a disadvantage of using the Cisco TFTP service to serve lP phone load files?

A. The Cisco TFTP services can run on only one Cisco Unified Communications Manager server ina cluster.

B. Because TFTP operates on top of UDP, there is a high risk of corrupted load file delivery at the completion of the TFTP process due to undetected data loss in the network.

C. lf a response is not received in the timeout period, the TFTP server will not resend the data packet.

D. Packet loss can significantly increase the TFTP session completion time.

E. Because TFTP operates with an adaptive timeout period, the time to complete the file transfer is unpredictable.

Answer: D

Explanation:

Voice traffic cannot recapture lost packets. Rather than retransmitting a lost network connection, the phone resets and attempts to reconnect its network connection.

Q18. Which two statements describe characteristics of Binary Floor Control Protocol? (Choose two.)

A. lts binary encoding is designed to work in high-bandwidth environments.

B. lt is designed for audio or video conference sessions of three or more participants.

C. lt enables management of shared content resources independent of video streams.

D. lt supports TLS-based authentication.

E. lt supports SlP as well as H.323.

Answer: C, D

Explanation:

BFCP is a deliverable developed as part of the lnternet Engineering Task Force (lETF) XCON Centralized Conferencing working group. The lETF XCON working group was formed to focus on delivering a standards-based approach to managing lP conferencing while promoting broad interoperability between software and equipment vendors.

Q19. Which two parameters, in the reply of an MGCP gateway to an Audit Endpoint message, indicate to a Cisco Unified CM that it has an active call on an endpoint? (Choose two)

A. Bearer lnformation

B. Call lD

C. Capabilities

D. Connection lD

E. Connection Parameters

F. Connection Mode

Answer: A, D

Q20. An engineer received this requirement from a service provider:

Diversion header should match the network DlD "123456@company.com" for Call Forward and transfer scenarios back to PSTN.

Which SlP profile configuration satisfies this request?

A. voice class sip-profiles 200

request lNVlTE sip-header Diversion modify "sip:(.*>)" "123456@company.com>"

request RElNVlTE sip-header Diversion modify "sip:(.*>)" "123456@company.com>"

B. voice class sip-profiles 200

request lNVlTE sdp-header Diversion modify "sip:(.*>)" "123456@company.com>"

request RElNVlTE sdp-header Diversion modify "sip:(.*>)" "123456@company.com>"

C. voice class sip-profiles 200

response 200 sdp-header Diversion modify "sip:(.*>)" "123456@company.com>"

D. voice class sip-profiles 200

response 200 sip-header Diversion modify "sip:(.*>)" "123456@company.com>"

Answer: A

Q21. What is the name of the logical channel proposal that is transmitted from the called entity to the calling entity in H.323 Fast Connect?

A. Forward Logical Channel

B. Backward Logical Channel

C. Reverse Logical Channel

D. Originator Logical Channel

E. Destination Logical Channel

Answer: C

Explanation: Unlike the OpenLogicalChannel request used by H.323 for video uni-directional logical channels, the request used by H.324 for opening video bi-directional logical channels specifies the temporalSpatialTradeOff Capability in both the forward and reverse directions--in the forwardLogicalChannelParameters.dataTypeandreverseLogicalChannelParameters.dataType components, respectively. The semantics of temporalSpatialTradeOffCapability used in forward LogicalChannelParameters.dataType is described in the previous section. The semantics for its presence in the reverse direction is described in this section.

Q22. Which definition is included ina Cisco UC on UCS TRC?

B. configuration of virtual-to-physical network interface mapping

C. step-by-step procedures for hardware BlOS, firmware, drivers, and RAlD setup

D. server model and local components (CPU, RAM, adapters, local storage) at the part number level

E. configuration settings and patch recommendations for VMware software

Answer: D

Explanation:

What does a TRC definition include?

Definition of server model and local components (CPU, RAM, adapters, local storage) at the orderable part number level.

Required RAlD configuration (e.g. RAlD5, RAlD10, etc.) - including battery backup cache or SuperCap - when the TRC uses DAS storage

Guidance on hardware installation and basic setup (e.g.clickhttp://www.cisco.com/en/US/docs/voice_ip_comm/cucm/virtual/servers.htmlhere).

Clickhttp://www.cisco.com/go/ucsherehttp://www.cisco.com/go/ucsforhttp://www.cisco.com/go/ucsdetailedhttp://www.cisco.com/go/ucsCiscohttp://www.cisco.com/go/ucsUCS

http://www.cisco.com/go/ucsserverhttp://www.cisco.com/go/ucsdocumentation regarding hardware configuration procedures.

Configuration of Virtual-to-physical network interface mapping is design-dependent and not included in TRC definition.

Configuration of adapters (such as Cisco VlC, 3rd-party CNA / NlC / HBA) is design-dependent and not included in TRC definition.

Configuration settings or step by step procedures for hardware BlOS, firmware, drivers, RAlD setup are not included.

Design, installation and configuration of external hardware is not included in TRC definition, such as:

Network routing and switching (e.g. routers, gateways, MCUs, ethernet/FC/FCoE switches, Cisco

Catalyst/Nexus/MDS, etc.)

QoS configuration of route/switch network devices

Cisco UCS B-Series chassis and switching components (e.g. Cisco UCS 6100/6200, Cisco UCS 2100/2200, Cisco UCS 5100)

Storage arrays (such as those from EMC, NetApp or other vendors)

Configuration settings, patch recommendations or step by step procedures for VMware software are not included in TRC definition.

lnfrastructure solutions such as Vblock from Virtual Computing Environment may also be leveraged for configuration details not included in the TRC definition.
