Which statement about the H.323 Fast Connect (also known as fast start) procedures is correct?

A.    Fast Connect shortens the call setup time by forcing all H.245 negotiations to take place earlier
during the H.225 message exchanges, setup time by allowing H.323 devices to propose and confirm
master-slave determination in H.225 message exchanges.
B.    Fast Connect shortens the call setup time by permitting calls to bypass certain H.225 steps and move
directly from H.225 setup to H.225 exchanges.
C.    Fast Connect shortens the call setup time by allowing H.323 devices to propose and confirm Open
Logical Channel in H.225 message connect.
D.    Fast Connect shortens the call setup time by allowing H.323 devices to use UDP as a transport
protocol for H.245 negotiation messages, exchanges.
E.    Fast Connect shortens the call reclaiming time that is otherwise used for TCP handshakes.

Which three statements are true about multicast IGMP snooping? (Choose three.)

A.    When a host in a multicast group sends an IGMP leave message, only that port is deleted from the
multicast group.
B.    An IP multicast stream to the IP host can be stopped only by an IGMP leave message.
C.    IGMP snooping does not examine or snoop Layer 3 information in packets that are 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.    IGMP control messages are transmitted as IGMP multicast packets so that they can be distinguished
from normal multicast data at Layer 2.
F.    A switch that is running IGMP snooping examines every multicast data packet to verify whether it
contains any pertinent IGMP “must control” information.

Answer: ADF

What are two advantages of multicast technologies? (Choose two.)
