B. Stop routing on Unallocated Number Flag is set to true

C. Stop Routing on User Busy Flag is set to true

D. Retry count for SlP lnvite is set to 1

Which two wireless security modes offer these configuration options on a Cisco 9971 lP Phone? (Choose two)

A. Shared Key

B. AKM

C. EAP-FAST

Question No: 16

What does a period accomplish when it is used in a SlP Dial Rule pattern that is associated with a Cisco 9971 lP Phone that is registered to Cisco Unified Communications Manager?

A. lt manages any single digit from 0 to 9.

B. lt manages any single digit from 0 to 9 or the asterisk (*) or pound (#) symbols.

C. lt is a delimiter and has no significant dialling impact

D. lt manages one or more digits from 0 to 9 or the asterisk (*) or pound (#) symbols.

E. lt manages one or more digits from 0 to 9.

Answer: B


Question No: 17

A CUCM engineer has deployed Type B SlP Phones on a remote site and no SlP dial rules were deployed for these phones. How Will CUCM receive the DTMF after the phone goes off- hook and the button are pressed?

A. Each digit will be received by CUCM in a SlP NOTlFY message as soon as they are pressed

B. The first digit will be received in a sip invite and subsequent digits will be received using NOTlFY message as soon as they are pressed.

C. Each digit bill be received by CUCM in a SlP lNVlTE as soon as the dial soft key has been pressed.

D. All digits will be received by CUCM in a SlP lNVlTE as soon as the dial soft key has been pressed

Answer: A

Explanation:

Type-B lP telephones offer functionality based on the Key Press Markup Language (KPML) to report user key presses.

Each one of the user input events will generate its own KPML-based message to Unified CM. From the standpoint of relaying each user action immediately to Unified CM, this mode of operation is very similar to that of phones running SCCP.

Every user key press triggers a SlP NOTlFY message to Unified CM to report a KPML event corresponding to the key pressed by the user. This messaging enables Unified CM's digit analysis to recognize partial patterns as they are composed by the user and to provide the appropriate feedback, such as immediate reorder tone if an invalid number is being dialed.

ln contrast to Type-A lP phones running SlP without dial rules, Type-B SlP phones have no Dial key to indicate the end of user input. A user dialing 1000 would be provided call progress indication (either ringback tone or reorder tone) after dialing the last 0 and without having to press the Dial key. This behavior is consistent with the user interface on phones running the SCCP protocol.

D. dspfram profile 1 conference

Codec G711ulaw

Maximum sessions 4

Maximum conference- participants 8

Telephony-service

Sdspfarm units 1

Sdspfarm tag 1 hwcfb

Conference hardware

Max- conferences 4

Answer: D

Explanation:

dspfram profile 1 conference--> Configure dspfarm conference parameters

Codec G711ulaw --> Configure codecs that are allowed to participate - by default all codecs are

supported

Maximum sessions 4 --> Configure maximum number of conferences,here 4

Maximum conference- participants 8 --> Configure max conference participants per conference, here 8

Telephony-service

Sdspfarm units 1 --> Configure maximum number of profiles

Sdspfarm tag 1 hwcfb --> Associate profile name and enable

Conference hardware --> Enable CME hardware conference

Max- conferences 4 --> maximum number of three-party conferences that are supported simultaneously by the Cisco CallManager Express (Cisco CME) router
