When configuring Cisco Unified Communications Manager, which configuration enables phones to automatically register to a Cisco Unified Communications Manager publisher when the connection to the subscriber is lost?
A. SRST
B. Device Pool
C. Cisco Unified CM Group
D. Route Group
The answer is Device Pool. The question is: which configuration enables Phones. On the phone you need to configure Device Pool, and the device pool has the UCM Group configuration with 2 nodes. This is a tricky question. The configuration on the PHONE is device pool.
Interesting that the question refers to “automatically register to a cisco unfied communications manager PUBLISHER”
I am confused with answer B and C, it is true that the Cisco Unified Communications Manager Group specifies a highlighted list of up to three Cisco Unified Communications Managers.
But, when a device registers, it attempts to connect to the primary (first) Cisco Unified Communications Manager in the group that is assigned to its DEVICE POOL. The Device Pool is really the one configured on the Phone.
Configure Cisco Unified CM Groups
Use this procedure to set up Unified Communications Manager Groups for call processing redundancy, load balancing and failover for the devices in the device pool.

SRST refer to Survivable Remote Site Telephony Configuration.(Gateway)
I think answer C is the correct.
The correct answer is : C
I agree
