Q57. Which message is used by a Cisco IOS MGCP gateway to send periodic keepalives to its call agent?
E. 200 OK
Q58. 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.
Q59. Refer to the exhibit.
Which DTMF relay method is advertised when the originating SIP gateway sends an INVITE message with a Call-Info header shown?
A. RFC 2833
B. SIP INFO
C. SIP NOTIFY

Q60. Which two statements describe security services that are provided by the Phone Proxy function on a Cisco ASA appliance? (Choose two.)
A. It is supported only on phones that use SCCP.
B. It is supported on an adaptive security appliance that runs in transparent mode.
C. It provides interworking to ensure that the external IP phone traffic is encrypted, as long as the Cisco Unified Communications Manager cluster runs in secure mode.
D. It provides a proxy of phone signaling, with optional use of NAT, to hide the Cisco Unified Communications Manager IP address from the public Internet.
E. It proxies phone media so that internal phones are not directly exposed to the Internet.
F. It supports IP phones that send phone proxy traffic through a VPN tunnel.
