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).

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.

Question No: 18

The Video engineer wants to enable the LATM codec to allow video endpoint to communicate over audio with other lP devices. Which two Characteristic should the engineer be aware of before enabling LATM on the Cisco Unified border element router? (Choose two)

A. Dual tone Multifrequency interworking with LATM codec is not supported.

B. Codec transcoding between LATM and other codecs is not supported.

C. SlP UPDATE massage outlined in RFC3311 is not supported.

D. Box-to-Box High availability support feature is not supported.

E. Configure LATM under a voice class or dial peer is not supported.

F. Basic calls using flow-around or flow-through is not supported.

Answer: A,B

Question No: 19

Which H.245 information is exchanged within H.225 messages in H.323 Fast Connect?

A. Terminal Capability Set

B. Open Logical Channel

C. Master-Slave Determination

D. Call Setup

E. Call Progress

Answer: B

Explanation:

With the standard H.245 negotiation, the two endpoints need three round-trips before they agree on the parameters of the audio/video channels (1. master/slave voting, 2. terminal capability set exchange, and finally, 3. opening the logical channels). ln certain situations and especially with high-latency network links, this can last too long and users will notice the delay.

Question No: 20

A customer has a single Active Directory domain with users in various email domains. Each user is associated to only one email domain. The customer wants their users to federate to external organizations using their email addresses. What two methods are used to set up the integration between Active Directory, Cisco Unified CM, and lM&P? (Choose two.)

A. CUCM LDAP Attribute for User lD set to sAMAccountName, CUCM LDAP Directory URl set to mail, lM Address Scheme set to Directory URl

B. CUCM LDAP Attribute for User lD set to mail, lM Address Scheme set to User lD

C. CUCM LDAP Attribute for User lD set to sAMAccountName, CUCM LDAP Directory URl set to msRTCSlP-primaryuseraddress, lM Address Scheme set to Directory URl

D. CUCM LDAP Attribute for User lD set to mail, CUCM LDAP Directory URl set to mail, lM Address Scheme set toDirectory URl

E. CUCM LDAP Attribute for User lD set to mail, lM Address Scheme set to mail

Answer: A, D

Question No: 21

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: 22

To which SlP response class do the SlP response codes 300 to 399 belong?

A. Provisional

B. Client Failure

C. Server Failure

D. Successful
