• Question 412:

  Calls are being delivered to the end user in the globalized format. Where does an engineer configure the calling number into a localized format?

  A. route pattern

  B. service parameters

  C. IP phone

  D. gateway

  Correct Answer: C

• Question 413:

  A user forwards a corporate number to an international number. What are two methods to prevent this forwarded call? (Choose two.)

  B. Block international dial patterns in the SIP trunk CSS.

• Question 414:

  Refer to the exhibit.

  

  This INVITE is sent to an endpoint that only supports G729. What must be done for this call to succeed?

  A. Nothing: both sides support G.729.

  B. Add a transcoder that supports G711ulaw and G.729.

  C. Add a media termination point that supports G.711ulaw and G.729.

  D. Nothing: both sides support payload type 101.

  Correct Answer: B

  A transcoder takes the media stream of one codec and transcodes (converts) it from one compression type to another compression type. For example, it could take a stream from a G.711 codec and transcode (convert) it in real time to a

  G.729 stream. In addition to codec conversion, a transcoder resource can also provide MTP/TRP functionality to a call.

• Question 415:

  Which command is used in Cisco IOS XE TDM gateway to configure the voice T1/E1 controller to provide clocking?

  A. clock source line

  B. Cisco IOS XE TDM gateway T1/E1 controller cannot provide clocking.

  C. clocking source internal

  D. clocking source network

  Correct Answer: D

• Question 416:

  Which issue causes slips on a PRI?

  A. incorrect clock source

  B. incorrect encapsulation

  C. incorrectly configured time zone

  D. change in the line code

  Correct Answer: A

  A router with multiple Primary Rate Interfaces (PRIs) can experience slip errors on one of the T1 PRIs. This happens when you have multiple clock sources. https://community.cisco.com/t5/collaboration-voice-and-video/slip-errors-are-seen-on-t1-pri-where-slip-secs-counter/ta-p/3124530#:~:text=Core%20Issue,you%20have%20multiple%20clock%20sources.

• Question 417:

  On which Cisco Unified Communications Manager nodes can the TFTP service be enabled?

  A. any node

  B. any two nodes

  C. only nodes that have Cisco Unified CM service enabled

  D. any subscriber nodes

  Correct Answer: A

  From the SRND:

  The Cisco TFTP service that provides this functionality can be enabled on any server node in the cluster. However, in a cluster with more than 1250 users, other services might be impacted by configuration changes that can cause the TFTP

  service to regenerate configuration files. Therefore, Cisco recommends that you dedicate a specific subscriber node to the TFTP service, as shown in Figure 9-1, for a cluster with more than 1250 users or any features that cause frequent

  configuration changes.

• Question 418:

  Multiple route patterns match a number. How does Cisco Unified Communications Managers determine which pattern to use?

  A. the one that comes first in numerical order

  B. the one with the longest match

  C. the one with the closest match

  D. the one that discards everything PreDot

  Correct Answer: C

• Question 419:

  An engineer must extend the corporate phone system to mobile users connecting through the internet with their own devices. One requirement is to keep that as simple as possible for end users. Which infrastructure element achieves these goals?

  A. Cisco Express Mobility

  B. Cisco Expressway-C and Expressway-E

  C. Cisco Unified Border Element D. Cisco Unified Instant Messaging and Presence

  Correct Answer: B

• Question 420:

  An engineer encounters third-party devices that do not support Cisco Discovery Protocol. What must be configured on the network to allow device discovery?

  A. LACP

  B. TFTP

  C. LLDP

  D. SNMP

  Correct Answer: C

  LLDP (Link Layer Discovery Protocol) is a vendor-neutral network discovery protocol that is used to discover the topology of a network. LLDP is similar to CDP (Cisco Discovery Protocol), but it is not proprietary to Cisco. LLDP is supported by a wide range of network devices, including switches, routers, and firewalls. To configure LLDP on a network, you must enable LLDP on the devices that you want to discover. You can then use a network management tool, such as Cisco Network Assistant, to view the topology of the network. The other options are incorrect. TFTP (Trivial File Transfer Protocol) is a network protocol that is used to transfer files between devices. LACP (Link Aggregation Control Protocol) is a network protocol that is used to aggregate multiple network links into a single logical link. SNMP (Simple Network Management Protocol) is a network protocol that is used to manage network devices.
