Questions & Answers for Cisco 642-446

Showing 1-15 of 118 Questions

Question #1 - Topic 0

Question #2 - Topic 0

What two types of calls can cause the Cisco Unified CallManager to send an ARQ to a
gatekeeper to determine if a call should be routed? (Choose two.)

A. calls routed to SIP gateways

B. calls routed to H.323 gateways

C. calls routed over an intercluster trunk

D. calls routed to MGCP gateways

Question #3 - Topic 0

Given the following information and answer the question

Each IP phone is making a conference call. Which conference resource does the fourth
conference use?

A. HW_CFB_1

B. HW_CFB_2

C. SW_CFB_1

D. SW_CFB_2

Question #4 - Topic 0

What is the process of digit matching?

A. Cisco Unified CallManager first performs a digit-by-digit analysis, looking for patterns that match the internal DNs. If no match is found, the dialed string is matched against the route patterns.

B. Cisco Unified CallManager collects all digits and compares them enbloc for patterns that match the internal DNs. If no match is found, the dialed string is matched against the route patterns.

C. Cisco Unified CallManager performs a digit-by-digit analysis, looking for patterns that match the internal DNs and ones that match the route patterns simultaneously.

D. Cisco Unified CallManager collects all digits and compares them enbloc for patterns that match the internal DNs and ones that match the route patterns simultaneously.

Question #5 - Topic 0

Which two methods can be used to build a SIP trunk from the Cisco Unified CallManager to
a SIP Registrar server and a backup Registrar server? (Choose two.)

A. Configure one SIP trunk to point to the SIP Registrar server and a second SIP trunk to point to the backup Registrar server. Use route groups and a route list to allow calls to be routed to the backup Registrar if the primary does not respond.

B. Add the SIP Registrar server and the backup Registrar server to the Device Pool assigned to the SIP trunk.

C. Configure a DNS SRV record name as the destination address of the SIP trunk.

D. Configure only the SIP Registrar Server in the SIP trunk; The UA message will include the IP address of the backup SIP trunk if the call cannot be set up by the SIP Registrar server.

Question #6 - Topic 0

VLAN ID (VID) is the identification of the VLAN, which is defined by the standard IEEE
802.1Q. VID has 12 bits and allows the identification of 4096 VLANs. It is be provided by
which of the following mechanism when an IP phone boots up?

A. CDP

B. TFTP

C. DHCP

D. Option 150

Question #7 - Topic 0

If you want to assign softkey templates in a window, how to open it? Choose THREE
possible methods:

A. Device > Phone Configuration

B. System > Device Pool Configuration

C. Device > Device Settings > Device Profile

D. System > Device Defaults Configuration

Question #8 - Topic 0

In a Cisco Unified Communications Manager system, what is the relationship between an
IP phone and its secondary subscriber? Which THREE statements are correct?

A. The IP Phone sends a TCP connect message.

B. The IP Phone sends a TCP keepalive message every 30 seconds.

C. The IP Phone registers with the primary system when the secondary system is unavailable.

D. The IP Phone attempts to register with the secondary system when the primary system is unavailable.

Question #9 - Topic 0

Everyone who dials the same Meet-Me number, which is usually for manager use, joins the
conference together. On the contrary, the ad hoc conference is started by an initiator and
only the initiator can add people into the conference. What will you do to block non-
managers from accessing these Meet-Me numbers, but they are still capable of initiating ad
hoc conferences?

A. Place the Meet-Me numbers in a partition that is only assigned to the CSS for the managers' phones.

B. Place the Meet-Me numbers in an MRGL that is only assigned to the managers' phones.

C. Place the conference bridge resource in an MRGL that is only assigned to the managers' phones.

D. Place the conference bridge resource in a partition that is only assigned to the CSS for the managers' phones.

Question #10 - Topic 0

When you use Cisco Unified Communications Manager Administration, each database
transaction requires an individual manual operation, while Bulk Administration Tool (BAT)
automates the process and achieves faster add, update, and delete operations. Which of
the following answer describes the Cisco Unified Communications Manager Bulk
Administration Tool in Cisco Unified Communications Manager 6.0?

A. Cisco Unified Communications Manager Auto-Register Phone Tool is part of Bulk Administration.

B. Cisco Unified Communications Manager BAT pages are available from the Serviceability page.

C. Cisco Unified Communications Manager BAT needs to be installed from the plug-in page.

D. Cisco Unified Communications Manager Auto-Register Phone Tool requires a Customer Response System.

Question #11 - Topic 0

The Session Initiation Protocol (SIP) is a signalling protocol, widely used for setting up and
tearing down multimedia communication sessions such as voice and video calls over the
Internet. If we didn't configure KPML (Keypad Markup Language) or a set of dial rules on a
SIP phone, how to send digits to Cisco Unified Communications Manager for further
processing?

A. the user must press the # key

B. the user must press the Dial softkey

C. the user must press the enbloc softkey

D. when the user finishes dialing, the digits will be sent automatically

Question #12 - Topic 0

Please match the function to the correct Barge

A. (I)-1,3,5 (II)-2,4,6

B. (I)-2,3,5 (II)-1,4,6

C. (I)-2,3,6 (II)-1,4,5

D. (I)-2,4,6 (II)-1,3,5

Question #13 - Topic 0

Cisco Unified Presence helps users quickly connect to their colleagues using the most
appropriate communications medium at any given time. If we use the Presence feature in a
Cisco Unified Communications network, which THREE of the determinations are
meaningful?

A. Determine if an IP phone has been unplugged if the phone is in the same Cisco Unified Communications cluster as the watcher.

B. Determine if an IP phone is on hook or off hook if the phone is outside the Cisco Unified Communications cluster of the watcher.

C. Determine if an IP phone is on hook or off hook if the phone is in the same Cisco Unified Communications cluster as the watcher.

D. Determine if a set of IP phones is on hook or off hook if if the phones are in the same Cisco Unified Communications cluster as the watcher.

Question #14 - Topic 0

You need to establish a connection from your Cisco Unified CallManager cluster to a
service provider's registrar server. Which trunk type should you select?

A. intercluster trunk (non-gatekeeper-controlled)

B. intercluster trunk (gatekeeper-controlled)

C. H.225 trunk (gatekeeper-controlled)

D. SIP trunk

Question #15 - Topic 0

The four locations of X are all connected via an IP WAN and each has a Cisco Unified
Communications Manager cluster, which is connected to the headquarters cluster via
intercluster trunks. The calls between them require dialing a 2-digit access code plus a 4-
digit extension. Eight calls can be made at a time cross the IP WAN. The calls will be sent
to Xs preferred long-distance carrier if there are more than eight or the IP WAN is not
available. Suppose it fails too, the local provider should be used. In order to successfully
make a long-distance call, 10 digits are required by the long-distance carrier, 11 digits by
the local provider, but only 7 digits are necessary for local calls.
How many route lists AT LEAST are necessary at the headquarters location?

A. 1

B. 2

C. 3

D. 4
