What is the primary difference between multicast and broadcast communications? (Choose 2)

Broadcasts are sent to every node on a specific network and/or subnet.
Multicasts are sent to all networks defined with multicast.
Multicasts are sent to all multicast group members.
Multicasts and broadcasts are essentially the same thing.

At which layer(s) of the OSI model do multicast protocols operate? (Choose two)

Layer 1
Layer 2
Layer 3
Layer 4
Layer 5

Which OSPF Link State Advertisement (LSA) type supports Multicast information?

LSA type 1
LSA type 2
LSA type 5
LSA type 6

Do Cisco routers support Multicast Open Shortest Path First - MOSPF?

Yes, completely
Not at all
Only on 3600 series routers and higher
It is contingent upon the IOS version

Using Internet Group Management Protocol, (IGMP) version 1, how can a node exit or stop participating in a multicast group?

It must time out because there is no explicit exit group statement.
The node must issue a specific leave statement.
The node has no control over multicast group participation; the router accomplishes multicast group management.
Both the node and the router must be administratively configured to NOT participate in a specific multicast group.

Using Internet Group Management Protocol, (IGMP) version 2, how can a node exit or stop participating in a multicast group?

It must time out because there is no explicit exit group statement.
The node must issue a specific leave statement.
The node has no control over the its group participation; group management is accomplished by the router.
Both the node and the router must be administratively configured to NOT participate in a specific multicast group.

Which multicast IP address is reserved for local routers?

224.0.0.1
224.0.0.2
224.0.0.10
223.0.0.1

Which protocol uses the IP addresses of 224.0.0.5 and 224.0.0.6 for multicast Communications?

EIGRP
OSPF
PIM
None of the above.

Which IOS command will display IP multicast group information?

show ip group multicast
show group igmp multicast
show ip igmp group
show ip group igmp

What is the definition of IP multicasting? (Choose 3)

IP multicasting is a series of protocols commonly used to address the short comings of basic broadcasts.
IP multicasting is a series of protocols that allow the selective forwarding of traffic based on layer 2 and layer 3 addressing to select groups of nodes.
IP multicasting is essentially the same as IP broadcasting but with some additional layer-3 functionality.
IP multicasting is a technology and series of protocols that allow broadcasts to selectively pass over layer-3 routed network boundaries according to specific multicast parameters.

Under IGMP version 1, must a node wait for a membership query time interval to pass before joining a multicast group?

Yes, the router(s) connecting to the LAN periodically poll the network requesting group member nodes to join.
Yes, multicast nodes periodically send multicast join statements (every 60 seconds) on the Local Area network. To join a multicast group, the node timer must time-out before broadcasting/advertising the desire to join a multicast group.
No, when a network node wants to join a multicast group, the node sends a host membership request to the all-router group address of 224.0.0.2.
No, when a network node wants to join a multicast group, the node establishes the group IP address that the local router will use. Subsequent nodes request multicast group membership from the router.
