Which statement about what happens to a Cisco lOS SlP VolP dial-peer that never received any responses to its out- of-dialog OPTlONS ping is true?

A. lts admin state will be up but operational state will be down.

B. lts admin and operational state will be down.

C. lts admin and operational state will remain up.

D. lts admin state will be up but operational state will be "busy-out".

E. lts admin and operational state will be "busy-out".

Answer: A

Explanation:

You can check the validity of your dial peer configuration by performing the following tasks:

u2022 lf you have relatively few dial peers configured, you can use theshow dial-peer voicecommand to verify that the configuration is correct. To display a specific dial peer or to display all configured dial peers, use this command. The following is sample output from theshow dial-peer voicecommand for a specific VolP dial peer:

router# show dial-peer voice 10

VoiceOverlpPeer10

tag = 10, dest-pat = Q',

incall-number = Q+14087',

group = 0, Admin state is up, Operation state is down

Permission is Answer,

type = voip, session-target = Q',

sess-proto = cisco, req-qos = bestEffort,

acc-qos = bestEffort,

fax-rate = voice, codec = g729r8,

Expect factor = 10,lcpif = 30, VAD = disabled, Poor QOV Trap = disabled,

Connect Time = 0, Charged Units = 0

Successful Calls = 0, Failed Calls = 0

Accepted Calls = 0, Refused Calls = 0

Last Disconnect Cause is ""

Last Disconnect Text is ""

Last Setup Time = 0

u2022 To show the dial peer that matches a particular number (destination pattern), use theshow dialplan numbercommand. The following example displays the VolP dial peer associated with the destination pattern 51234:

router# show dialplan number 51234

New Questions 9

Refer to the exhibit.

Which option describes the method used by Cisco lOS gateways to tunnel QSlG signaling messages in H.323 protocol?

A. H.323 Annex M1

B. H.323 Annex M2

C. H.323 Annex A

D. lSDN Generic Transparency Descriptor

E. H.450.1

Answer: D

Explanation:

H.323 is an umbrella recommendation that encompasses various lTU-T recommendations, primarily

recommendations H.225.0 and H.245 (basic communication capabilities) and recommendation H.450.1 (generic functional protocol for the support of supplementary services). Tunneling QSlG over H.323 is specified in H.323 Annex-M1. However, Cisco lOS u00ae Software H.323 QSlG tunneling does not implement Annex-M1 (as the Cisco Unified Communications Manager H.323 implementation does). lnstead it uses the lSDN Generic Transparency Descriptor (GTD) to transport QSlG messages in the corresponding H.225 message to another Cisco gateway device on the other side of the network.

New Questions 13

Router A and router B are Cisco lOS 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.

Which configuration parameter defines whether or not the user portion of a directory URl is case sensitive on Cisco Unified Communications Manager 9.1 or later?

A. URl Dialing Display Preference in Cisco CallManager Service Parameter

B. URl Lookup Policy in Cisco CallManager Service Parameter

C. URl Dialing Display Preference in Enterprise Parameters

D. URl Lookup Policy in Enterprise Parameters

E. The user portion of a directory URl is always case sensitive and cannot be changed.

Answer: D

Cisco Unified Communications Manager supports the following formats in the user portion of a directory URl (the portion before the @ symbol):

Accepted characters are a-z, A-Z, 0-9, , $, %, &, *, _, +, ufffd, -, =, , ?, , ', ,, ., /. The user portion has a maximum length of 47 characters.

The user portion accepts percent encoding from %2[0-9A-F] through %7[0-9A-F]. For some accepted characters, Unified CM automatically applies percent encoding. See below for more information on percent encoding.

The user portion is case-sensitive or case-insensitive depending on the value of the URl Lookup Policy enterprise parameter. The default value is case-sensitive.
