Q121. Refer to the exhibit. 

All HQ phones are configured to use HQ_MRGL and all BR phones are configured to use BR_MRGL. For the HQ phones always to use the hardware conference bridge as a first choice, which configuration should be implemented? 

A. Ensure that both the hardware and software conference bridges are listed in the HQ_MRG. Ensure that the instance ID for the hardware conference bridge is 0. 

B. Ensure that both the hardware and software conference bridges are listed in the HQ_MRG. The hardware conference bridge must be configured first. 

C. Assign the hardware conference bridge to HQ_MRG. Configure a second HQ_MRG_2 and assign the software conference bridge to it. Add both the HQ_MRG and HQ_MRG_2 to the HQ_MRGL and list the HQ_MRG first. 

D. Assign the hardware conference bridge to HQ_MRG. Configure a second HQ_MRG_2 and assign the software conference bridge to it. Configure an additional HQ_MRGL_2. Add the HQ_MRG to HQ_MRGL. Add HQ_MRG_2 to HQ_MRGL_2. The HQ_MRGL should be assigned to the HQ phones. The HQ_MRGL_2 should be assigned to the HQ device pool. 

Answer:

Explanation: 

Expiation: 

To ensure that the hardware bridge is utilized first with all its resources BEFORE the software bridge is used … you need to have two separate MRG’s and list the hardware MRG 1st in the MRGL … 


Q122. Where do you specify the device mobility group and physical location after they have been configured? 

A. phones 

B. DMI 

C. device mobility CSS 

D. device pool 

E. MRGL 

F. locale 

Answer:

Explanation: 

Incorrect Answer: A, B, C, E Before you configure a device pool, you must configure the following items if you want to choose them for the device pool, Cisco Unified Communications Manager group (required), Date/time group (required). Region (required) , SRST reference (optional). Media resource group list (optional), Calling search space for auto-registration (optional). Reverted call focus priority (optional), Device mobility group (optional), Device mobility calling search space, Physical location (optional). Location, AAR group. AAR calling search space. Link:

Q123. Which task must you perform before deleting a transcoder? 

A. Delete the dependency records. 

B. Unassign it from a media resource group. 

C. Use the Reset option. 

D. Remove the device pool. 

E. Remove the subunit. 

F. Delete the common device configuration. 

Answer:


Q124. How is the region assigned to a device such as an IP phone? 

A. Regions are assigned directly in the device configuration page. 

B. Regions can be assigned only through a device pool. 

C. Regions can be assigned either directly on the device configuration page or through the device pool. If both configurations exist, the device pool region configuration takes precedence. 

D. Regions can be assigned either directly on the device configuration page or through the device pool. If both configurations exist, the device region configuration takes precedence. 

Answer:


Q125. Which statement about H.323 Gatekeeper Call Admission Control is true? 

A. Gatekeeper Call Admission Control applies to centralized Cisco Unified Communications deployments that use locations based Call Admission Control. 

B. Gatekeeper Call Admission Control applies to distributed Cisco Unified Communications deployments. 

C. Gatekeeper Call Admission Control applies only to distributed Cisco Unified Communications Express deployments. 

D. Gatekeeper Call Admission Control setting is configured in Cisco Unified Communications Manager. 

Answer:

Explanation: 

Incorrect Answer: A, C, D in distributed call processing deployments on a simple hub-and-spoke topology, you can implement call admission control with a Cisco IOS gatekeeper. In this design, the call processing agent (which could be a Unified CM cluster, Cisco Unified Communications Manager Express (Unified CME), or an H.323 gateway) registers with the Cisco IOS gatekeeper and queries it each time the agent wants to place an IP WAN call.

Q126. Refer to the exhibit. 

All HQ phones are configured to use HQ_MRGL and all BR phones are configured to use BR_MRGL. For the HQ phones always to use the hardware conference bridge as a first choice, which configuration should be implemented? 

A. Ensure that both the hardware and software conference bridges are listed in the HQ_MRG. Ensure that the instance ID for the hardware conference bridge is 0. 

B. Ensure that both the hardware and software conference bridges are listed in the HQ_MRG. The hardware conference bridge must be configured first. 

C. Assign the hardware conference bridge to HQ_MRG. Configure a second HQ_MRG_2 and assign the software conference bridge to it. Add both the HQ_MRG and HQ_MRG_2 to the HQ_MRGL and list the HQ_MRG first. 

D. Assign the hardware conference bridge to HQ_MRG. Configure a second HQ_MRG_2 and assign the software conference bridge to it. Configure an additional HQ_MRGL_2. Add the HQ_MRG to HQ_MRGL. Add HQ_MRG_2 to HQ_MRGL_2. The HQ_MRGL should be assigned to the HQ phones. The HQ_MRGL_2 should be assigned to the HQ device pool. 

Answer:


Q127. What is the purpose of a SAF Client? 

A. To decode address information and route calls to and from the end points 

B. To pass IP information from the CUCM to the endpoint 

C. To learn about and advertise or subscribe information about SAF network services 

D. To reside in the Cisco IOS software, and to communicate with the SAF forwarder 

Answer:


Q128. Refer to the exhibit. 

If an IP phone in San Jose roams to New York, which two IP phone settings will be modified by Device Mobility so that the phone can place and receive calls in New York? (Choose two.) 

A. The physical locations are not different, so the configuration of the phone is not modified. 

B. The physical locations are different, so the roaming-sensitive parameters of the roaming device pool are applied. 

C. The device mobility groups are the same, so the Device Mobility-related settings are applied in addition to the roaming-sensitive parameters. 

D. The Device Mobility information is associated with one or more device pools other than the home device pool of the phone, so one of the associated device pools is chosen based on a round-robin load-sharing algorithm. 

E. The Device Mobility information is associated with the home device pool of the phone, so the phone is considered to be in its home location. Device Mobility will reconfigure the roaming-sensitive settings of the phone. 

Answer: B,C 


Q129. 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:
