endpoint?
A. The MCU must register with the Cisco CallManager as an alternate gatekeeper.
B. The MCU must register with the gatekeeper, and the Cisco CallManager must register with
the MCU with a H.225 trunk.
C. The MCU must register with a H.225 gatekeeper-controlled trunk to the gatekeeper, and the
Cisco CallManager must be registered with the gatekeeper.

Question: 24
A large enterprise solution uses a pair of gatekeepers for Call Admission Control. Each
gatekeeper has multiple zones that are associated with it. Each zone has both voice and video
gateways. The video gateways support both H.320 and H.323 video room systems. The customer
requires the gatekeeper to provide video Call Admission Control and to facilitate video call routing
to each type of video gateway. What should you do to meet these requirements?
A. Assign a separate intrasite access code for each type of video endpoint.
B. Assign a translation pattern that support only H.320 to H.320, and a different pattern for
H.323 to H.323 calls.
C. Assign each site a service prefix that will allow the gatekeeper to provide the appropriate Call
Admission Control and call routing.
D. Assign technology prefixes to each type of gateway so that the gatekeepers can provide the
appropriate Call Admission Control and call routing to each call type.
Answer: D
Question: 25
You are working with a university that delivers customized training to the K-12 schools in the state
through a videoconferencing solution. The state has contracted with a local service provider for
an MPLS-based IP WAN that connects all the universities and K-12 school systems in the state.
The university needs now to provide a solution that will request a specified level of throughput
from the IP WAN via RSVP. Which device should the university investigate for this purpose?
