Q41. Refer to the exhibit. 

The exhibit shows the Cisco IOS CLI output of debug ip dhcp packet, which was captured on a router that is located at a branch office where a single IP phone is located. There is a standalone Cisco Unified Communications Manager server at the central site, which also provides DHCP services to the IP phone at the branch office. You are troubleshooting a problem where the IP phone could not register to Cisco Unified Communications Manager. You have confirmed that the IP phone received an IP address in the correct subnet and with a correct subnet mask from the DHCP server. Assuming the IP phone is correctly defined on Unified CM, which two statements about the network components are true? (Choose two.) 

A. The MAC address of the IP phone is 01ec44761e3e. 

B. The IP address of the DHCP server is 10.101.15.1. 

C. The MAC address of the VLAN 101 interface is ec44761e3e7d. 

D. The IP address of the VLAN 101 interface is 10.101.15.1. 

E. There is IP connectivity between the VLAN 101 interface of the branch router and the ip-helper address that is configured on this interface. 

F. There is IP connectivity between the IP phone and the ip-helper address on the VLAN 101 interface. 

Answer: DE 


Q42. Which two types of devices on Cisco Unified Communications Manager support iSAC? (Choose two.) 

A. MGCP 

B. SIP 

C. SCCP 

D. Music on Hold server 

E. H.323 

Answer: BC 


Q43. Which statement describes the Cisco best practice recommendation about priority queue bandwidth allocation in relationship to the total link bandwidth when multiple strict priority LLQs are configured on the same router interface? 

A. Each LLQ should be limited to one-third of the link bandwidth capacity. 

B. The sum of all LLQs should be limited to two-thirds of the link bandwidth capacity. 

C. The sum of all LLQs should be limited to one-half of the link bandwidth capacity. 

D. The sum of all LLQs should be limited to one-third of the link bandwidth capacity. 

E. Cisco does not recommend more than one strict priority LLQ per interface. 

Answer:


Q44. Router A and router B are Cisco IOS routers with hardware CFB resources that are registered to the same Cisco Unified Communications Manager server. Which Media Resource Group and Media Resource Group List configuration should be implemented if an administrator wants to make sure that all provisioned DSPs on router A are consumed before router B's DSP is used? 

A. Router A's CFB and router B's CFB should each be configured in its own MRG. Both MRGs should then be grouped into the same MRGL, but the MRG that contains router A's CFB should be listed in higher order than the MRG that contains router B's CFB. Finally, associate the MRGL to all conference resource consumers. 

B. Router A's CFB and router B's CFB should each be configured in its own MRG. Both MRGs should then be further separated into different MRGLs. Finally, associate the MRGL that contains router A's CFB in higher order than router B's CFB to all conference resource consumers. 

C. Router A's CFB and router B's CFB should both be configured in the same MRG with router A's CFB listed higher than that of router B. Then associate the MRG with an MRGL and apply it to all conference resource consumers. 

D. Router A's CFB and router B's CFB should both be configured in the same MRG. Make sure router A's CFB is listed in a higher alphabetical order than router B's CFB. Then associate the MRG with an MRGL and apply it to all conference resource consumers. 

E. Router A's CFB and router B's CFB should both be configured in the same MRG. Use Cisco Unified Communications Manager service parameters to assign a higher priority to router A's CFB. Then associate the MRG with an MRGL and apply it to all conference resource consumers.
