QUESTION 11:
Certkiller .com has a small group of users who do interactive video teaching from
H.323 endpoints to H.320 videoconferencing systems. What should you do so that
incoming calls can reach endpoints that are associated with a specific E.164
address?
A. Deploy an IPCC server and configuration an IVR to act as a front end to the MCU
B. Enable the DID capability that is built into the gateway
C. Deploy the Cisco IP IVR
D. Configure the DID in the Cisco CallManager
642-481
Actualtests.com – The Power of Knowing
Answer: B
QUESTION 12:
Certkiller .com would like to provide customized voice prompts for users who are dialing
into videoconferences. Which component should be used to support customized voice
prompts?
A. Cisco CallManager
B. the IVR built into the gateway
C. the IVR built into the video gateway
D. Cisco peripheral gateway
E. the built-in IVR of the MCU
Answer: E
Explanation:
A 3500 MCU is acting as gateway (IPVC 3521, 3526 or 3540 with gateway module called MCU gateway)
than answer E is correct, but answer C seems to me also a correct answer as we are talking here about a
video gateway device with built in IVR.
QUESTION 13:
A new site is being planned with video terminals that support a maximum data rate of
768 kbps each. A DS-3 link with 45 Mbps is available for the site. Based on Cisco
guidelines, how many video terminals can be placed at this site, considering that no Call
Admission Control is available?
A. 2
B. 4
C. 8
D. 16
E. 32
F. 64
Answer: D
QUESTION 14:
When routing to both audio and video devices, with which device does Cisco recommend
enabling AAR?
A. Tandberg SCCP endpoint
B. H.323 client
C. IP phone
642-481
Actualtests.com – The Power of Knowing
D. Cisco VT Advantage
Answer: C
QUESTION 15:
How is a H.323 MCU defined in Cisco CallManager so that H.323 endpoints can
communicate with endpoints that are controlled by Cisco CallManager?
A. as a H.320 gateway
B. as a H.323 gateway
C. as a gatekeeper-controlled H.225 trunk
D. as a gatekeeper-controlled intercluster trunk
Answer: B
Explanation:
H.323 calls from Cisco Callmanager to the MCU do not necessarily have to go through the gatekeeper.
The MCU can be configured directly in the Cisco CallManager as an H.323 gateway device.
This is only applicable in an all-SCCP network or where all of the H.323 endpoints are also registered
directly with the Cisco CallManager.
So B is the correct answer.
QUESTION 16:
Which device manages a H.323 zone that is composed of terminals, gateways, and
MCUs?
A. Media Termination Point
B. Cisco IOS Gateway
C. gatekeeper
D. firewall
E. proxy
Answer: C
QUESTION 17:
Certkiller .com has deployed a centralized call-processing model in the organization. The
customer would now like to deploy a Cisco VT Advantage camera on each IP phone to
facilitate video calls and videoconferences. The customer has deployed a gatekeeper to
provide Call Admission Control for the IP WAN. If the customer adds an MCU to each
site, how will this impact the manner in which the media resource groups are configured
in the Cisco CallManager cluster?
A. There will not be any impact to the MRGs; only the order in which the MRGs are
642-481
Actualtests.com – The Power of Knowing
chosen in the MRGL will be impacted.
B. There will be separate MRGLs for IP phones and Cisco VT Advantage cameras, but
each MRGL will use the same MRG to provide DSP support.
C. Each Cisco VT Advantage camera will have a separate MRGL assigned to it, and this
list will use an MRG that has dedicated resources for that specific type of device.
D. Each device will be assigned an MRGL that will include an ordered list of all the
MRGs available.
Answer: D
QUESTION 18:
You have Certkiller .com that has a legacy H.320 videoconferencing system. The
customer recently migrated to a converged network for voice and data, and would now
like to include video. New ISDN gateways have been deployed to connect the legacy
H.320 systems to the IP network. How should the Cisco CallManager cluster be
configured so that the gatekeeper can provide Call Admission Control and resolve E.164
addresses?
A. E.164 addresses will be managed by the Cisco CallManager cluster, and the
gatekeeper will manage the CAC for the LAN and WAN.
B. An intercluster trunk will be configured from the Cisco CallManager cluster to each of
the new video gateways, and E.164 addressing and CAC will be managed by the
gatekeeper.
C. Each new gateway will be included in the Cisco CallManager configuration through
an MRG and an MRGL, and use locations-based CAC.
D. A H.225 trunk will be configured between the gatekeeper and the Cisco CallManager
cluster;the gatekeeper will resolve the E.164 addresses and manage CAC for the IP
WAN.
Answer: D
QUESTION 19:
Certkiller .com is interested in deploying Cisco VT Advantage cameras along with H.323
video room systems at the facility. How should MRGs be configured to support IP
phones, Cisco VT Advantage cameras, and H.323 video room systems with Cisco IPVC
3511 Multipoint Control Units?
A. One MRG would be required to support the IP phones, Cisco VT Advantage cameras,
and H.323 video room systems.
B. Two MRGs would be required, one to support IP phones, and one to support Cisco VT
Advantage cameras and H.323 video room systems.
C. Three MRGs would be required, one to support IP phones, one to support Cisco VT
Advantage cameras, and one to support the H.323 video room systems.
D. Four MRGs would be required, one to support conferencing and transcoding
642-481
Actualtests.com – The Power of Knowing
resources, one to support IP phones, one to support Cisco VT Advantage cameras, and
one to support H.323 video room systems.
Answer: B
QUESTION 20:
Certkiller .com has a conferencing network that is used by only H.323 endpoints.
Certkiller .com wants the ability to include SIP endpoints in conferences. What needs to
be done to allow SIP and H.323 endpoints in the same conferences?
A. Cluster H.323 MCUs with SIP MCUs.
B. Segment the MCU ports as either H.323 or SIP ports.
C. Configure the MCU to register with a gatekeeper and SIP proxy servers, and configure
the SIP protocol parameters.
