Which three options correctly describe the role of a subsequent node in a Cisco Unified CallManager 5.0 cluster? (Choose three.)
A.
processes IP telephony calls
B.
collects CDRs
C.
replicates the database to other Cisco Unified CallManager servers
D.
maintains read-only copies of the configuration database
E.
maintains writeable copy of the configuration database
F.
can have only one in a Cisco Unified CallManager cluster
Explanation:
The configuration database is stored on the First Node server, and a read-only copy is replicated to the Subsequent Node members of the cluster. Servers in a CallManager cluster can be configured to perform a single function or can have combined function, a function of a subsequent node is call-processing, which can be defined to server as a primary or backup call-processing server. The subsequent nodes collect CDRs and are forwarded to the first node (CDR Repository node), which the CAR services are active.
