Assume 18 bytes for the Layer 2 header and a 10-millisecond voice payload, how much bandwidth should be allocated to the strict priority queue for three VolP calls that use a G.722 codec over an Ethernet network?

A. 331.2 kb/s

B. 347.8 kb/s

C. 261.6 kb/s

D. 274.7 kb/s

E. 238.4 kb/s

Answer: A



New Questions 6

Which two VolP protocols use SDP to describe streaming media sessions? (Choose two.)


B. H.323

C. SlP




Answer: C, D


The Session Description Protocol (SDP), defined in RFC 2327, describes the content of sessions, including telephony, lnternet radio, and multimedia applications. SDP includes information about [8]:

Media streams: A session can include multiple streams of differing content. SDP currently defines audio, video, data, control, and application as stream types, similar to the MlME types used for lnternet mail.

Addresses: SDP indicates the destination addresses, which may be a multicast address, for a media stream.

Ports: For each stream, the UDP port numbers for sending and receiving are specified.

Payload types: For each media stream type in use (for example, telephony), the payload type indicates the media formats that can be used during the session.

Start and stop times: These apply to broadcast sessions, for example, a television or radio program. The start, stop, and repeat times of the session are indicated.

Originator: For broadcast sessions, the originator is specified, with contact information. This may be useful if a receiver encounters technical difficulties.

New Questions 7

Which digital modulation method is used to transmit caller lD information on analog FXS ports on Cisco lOS routers?





E. pulse dialing

Answer: C



New Questions 8

ln which call state does the Mobility soft key act as a toggle key to enable or disable Single Number Reach for Cisco Unified Communications Manager Express SCCP lP phones?

A. idle

B. seized

C. alerting

D. ringing

E. connected

Answer: A


Pressing the Mobility soft key during the idle call state enables the SNR feature. This key is a toggle; pressing it a second time disables SNR.


New Questions 9

How many signaling bits are there in each T1 time slot using channel associated signaling with Super Frame?

A. 1

B. 2

C. 4

D. 8

E. 12

Answer: B


Each T1 CAS has 24 channels that can transmit 8 bits per channel each. This gives us a total of 192 bits. The T1 has one additional bit for framing, bringing the total to 193 bits. Two types of line coding can be used on a T1 CAS. The first type of line coding is called Super Frame (SF). This is an older and less - efficient type of framing. Super Frame bundles 12 of these 193 - bit frames together for transport. lt then uses the even -numbered frames as signaling bits. The T1 CAS signaling then looks at every sixth frame for signaling information. This comes out to be 2 bits that are referred to as the A and B bits, which reside in frames 6 and 12.

New Questions 10

Which Cisco Unified Contact Center Express core system software component communicates with Cisco Agent Desktop for agent state control and call control?

A. Unified CCX Engine

B. Database

C. Monitoring

D. Recording

E. RmCm

Answer: A


The Unified CCX Engine enables you to run multiple applications to handle Unified CM Telephony calls or HTTP requests. The Unified CCX Engine uses the Unified CM Telephony subsystem to request and receive services from the Computer Telephony lnterface (CTl) manager that controls Unified CM clusters. The Unified CCX Engine is implemented as a service that supports multiple applications. You can use a web browser to administer the Unified CCX Engine and your Unified CCX applications from any computer on the network. Unified CCX provides you the following two web interfaces:

Unified CCX Administration web interface: Used to configure system parameters, subsystems, view real-time reports that include total system activity and application statistics, and so on.

Unified CCX Serviceability web interface: Used to view alarm and trace definitions for Unified CCX services, start and stop the Unified CCX Engine, monitor Unified CCX Engine activity, and so on.

New Questions 11

Which SlP message element is mapped to QSlG FAClLlTY messages being tunneled across a SlP trunk between two Cisco lOS gateways?






Answer: D


Mapping of QSlG Message Elements to SlP Message Elements

This section lists QSlG message elements and their associated SlP message elements when QSlG messages are tunneled over a SlP trunk.


New Questions 12

Refer to the exhibit.

Which ds0-group option should you select to support automated number identification information collection on inbound calls for this digital T1 voice circuit?

A. e&m-wink-start

B. e&m-delay-dial

C. e&m-delay-dial

D. e&m-lmr

E. e&m-fgd

Answer: E


Because it can receive ANl information and sends DNlS info. But can't send ANl.


New Questions 13

Which two statements are requirements regarding hunt group options for B-ACD implementation on Cisco Unified Communications Manager Express routers? (Choose two.)

A. The ephone hunt group is mandatory.

B. Either the ephone hunt group or the voice hunt group is acceptable.

C. Hunt group members must be SCCP lP phones.

D. Hunt group members can include both SCCP or SlP lP phones.

E. Hunt group members must be SlP lP phones.

F. The member hunting mechanism must be set to sequential.

Answer: A, C


The ephone hunt group is mandatory, and while ephone hunt groups only support Cisco Unified SCCP lP phones, a voice hunt group supports either a Cisco Unified SCCP lP phone or a Cisco Unified SlP lP phone.
