Question: 17
Company.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 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
