Which of the following does not accurately describe the database layer service in CM?
A. The database layer is a set of DLLs that provide a common access point for data insertion, retrieval,
and modification of the database.
B. The database information itself is made up of one publisher database, which is the very 1st CallManager
Machine in the CM cluster. All remaining machines in a cluster are subscriber databases.
C. The publisher maintains a TCP connection with each subscriber database. For real-time processing
and call processing, each CallManager maintains a TCP connection with every other CallManager via
the Intra Cluster Communications Signalling (ICCS) protocol.
D. The database layer monitors access to the Publisher. During a failure, it will try a replicated database
for device information and monitor the publisher for its return.
E. All database records including Call Detail Records (CDR) are replicated from publisher to subscriber.

Which of the following is NOT true about Multicast IGMP Snooping?
A. When a host in a multicast group sends a IGMP leave message, only that port is deleted from the
multicast group.
B. An IP multicast stream to the IP host can only be stopped by an IGMP Leave message.
C. IGMP snooping requires the LAN switch to examine, or snoop, some Layer 3 information in the IGMP
packets sent between the hosts and the router.
D. When the switch hears the IGMP host report from a host for a particular multicast group, the switch
adds the host’s port number to the associated multicast table entry.
E. Because IGMP control messages are transmitted as multicast packets, they are indistinguishable from
multicast data at Layer 2.
F. A switch running IGMP snooping examine every multicast data packet to check whether it contains any
pertinent IGMP must control information.
