Q31. When an incoming PSTN call arrives at an H.323 gateway, how does the called number get normalized to an internal directory number in Cisco Unified Communications Manager? 

A. Normalization is done by configuring the significant digits for inbound calls on the H.323 gateway configuration in Cisco Unified Communications Manager. 

B. Normalization is done using route patterns. 

C. Normalization is done using the gateway incoming calling party prefixes based on number type. 

D. Normalization is achieved by local route group that is assigned to the H.323 gateway. 

Answer:


Q32. Refer to the exhibit. 

The exhibit shows centralized Cisco Unified Communications Manager configuration components for TEHO calls to U.S. area code 408 from the U.K. The PSTN access code for the U.K. is 9 and 001 for international calls to the U.S. Assuming the PSTN does not accept globalized numbers with + prefix. What should the Called Party Transformation Pattern at the U.S. gateway be configured as? 

A. \+.! with the following Called Party Transformation:Discard Digits PreDot Prefix Digits Outgoing Calls: + 

B. \+1.! with the following Called Party Transformation:Discard Digits PreDot Prefix Digits Outgoing Calls: None 

C. \+408.! with the following Called Party Transformation:Discard Digits PreDot Prefix Digits Outgoing Calls: 1 

D. \+1408.! with the following Called Party Transformation:Discard Digits PreDot Prefix Digits Outgoing Calls: None 

E. \+1.408! with the following Called Party Transformation:Discard Digits PreDot Prefix Digits Outgoing Calls: None 

Answer:


Q33. Refer to the exhibit. 

HQ_MRGL is assigned to the HQ IP phones. BR_MRGL is assigned to the BR IP phones. The remote site BR IP phones support only the G.711 codec. Where should the transcoder reside? 

A. The transcoder should reside at the HQ site and assigned to HQ_MRG. 

B. The transcoder should reside at the BR site and assigned to BR_MRG. 

C. The transcoder should be assigned to its own MRG, which should then be assigned to the default device pool. 

D. A transcoder is not needed. The HQ phones will automatically change over to the G.711 codec. 

Answer:


Q34. Which method can be used to address variable-length dial plans? 

A. Overlap sending and receiving. 

B. Add a prefix for all calls that are longer than 10-digits long 

C. Use nested translation patterns to eliminate inter-digit timeout 

D. Use the @macro on the route pattern 

E. Use MGCP gateways, which support variable-length dial plans 

Answer:

Explanation: 

Incorrect Answer: B, C, D, E If the dial plan contains overlapping patterns, Cisco Unified Communications Manager does not route the call until the interdigit timer expires (even if it is possible to dial a sequence of digits to choose a current match). Check this check box to interrupt interdigit timing when Cisco Unified Communications Manager must route a call immediately. By default, the Urgent Priority check box displays as checked. Unless your dial plan contains overlapping patterns or variable length patterns that contain!, Cisco recommends that you do not uncheck the check box. Link:

Q35. If the device pool in the phone record does not match the device pools in the matching subnet, what will the system consider the phone to be? 

A. roaming 

B. unregistered 

C. unknown 

D. new device 

Answer:


Q36. Which option describes the reason that transcoding resources are added in Cisco Unified Communications Manager? 

A. to enable transcoding resources in a Cisco Unified Communications Manager server 

B. to enable Cisco Unified Communications Manager to select the optimal single codec for end-to-end calls 

C. to enable transcoding resources in Cisco IP Phones 

D. to provide transcoding resources in Cisco IOS gateways to Cisco Unified Communications Manager 

Answer:


Q37. When you configure Cisco Unified Communications Manager, you need to configure the router for Survivable Remote Site Telephony in case the Cisco Unified Communications Manger stops working. On which two factors would the number of IP phones and Directory Numbers that can register to the SRST router depend? (Choose two.) 

A. The protocol that is used in Cisco Unified Communications Manager 

B. Cisco Unified Communications Manager version 

C. Cisco IOS Software version 

D. WAN link bandwidth 

E. capacity of the Cisco Media Convergence Server 

F. router platform 

Answer: C,F 


Q38. What is the standard Layer 3 DSCP media packet value that should be set for Cisco TelePresence endpoints? 

A. CS3 (24) 

B. EF (46) 

C. AF41 (34) 

D. CS4 (32) 

Answer:


Q39. Which statement best describes globalized call routing in Cisco Unified Communications Manager? 

A. All incoming calling numbers on the phones are displayed as an E.164 with the + prefix. 

B. Call routing is based on numbers represented as an E.164 with the + prefix format. 

C. All called numbers sent out to the PSTN are in E.164 with the + prefix format. 

D. The CSS of all phones contain partitions assigned to route patterns that are in global format. 

E. All phone directory numbers are configured as an E.164 with the + prefix. 

Answer:

Explanation: 

Incorrect Answer: A, C, D, E For the destination to be represented in a global form common to all cases, we must adopt a global form of the destination number from which all local forms can be derived. The + sign is the mechanism used by the ITU's E.164 recommendation to represent any PSTN number in a global, unique way. This form is sometimes referred to as a fully qualified PSTN number.

Q40. Which two configurable options are available to enable Early Offer for calls over a Cisco Unified Communications Manager SIP trunk? (Choose two.) 

A. No Media Termination Point Required 

B. Media Termination Point Required 

C. Accept Audio Codec Preferences in Received Offer
