QUESTION 21
What is the purpose of using device pools?
642-445
www.actualtest.org – The Power of Knowing
A. to provide an easily modified set of system parameters for the Cisco Unified
CallManager server and endpoints
B. to provide all the IP phone parameters required for auto-registration
C. to consolidate the dial plan for a set of IP phones in the same location
D. to provide a convenient way to define a set of common characteristics that can be
assigned to devices
Answer: D
Explanation:
Device pools are user configurable sets of defaults that are assigned to devices as a single
function. The devices then inherit all the settings from the device pool that they are assigned.
This can be used to scale and simplify the distribution of CallManager groups, which are
discussed below. A device pool allows primary attributes to be assigned globally to a device. The
required components for a Device Pool are: Device Pool Name, CallManager Group, Date/Time
Group, Region, Softkey Template, SRST Reference. Some optional fields are: Calling Search
Space for Auto-Registration, Media Resource Group List, User Hold MOH Audio Source.
QUESTION 22
What causes an IP phone to register with the SRST router when the IP WAN fails?
A. The IP WAN interface on the SRST router goes down and triggers an SRST operation.
B. The IP phone loses keepalives from the Cisco Unified CallManager and reregisters
with the SRST.
C. The SRST sends an INVITE message to the IP phone when the IP WAN fails.
D. The SRST router stops receiving keepalives from the Cisco Unified CallManager and
falls back to the SRST.
E. The IP phone receives a new configuration to register with the SRST router when it
becomes active.
Answer: B
Explanation:
When the WAN link fails, Cisco IP phones detect that they are no longer receiving keepalive
packets from the Cisco CallManager. Cisco IP phones then register with the router, using Skinny
Client Control Protocol over TCP port 2000. In this instance, the SRST software automatically
activates and builds a local database of all Cisco IP phones attached to it, up to the maximum
amount set.
