What are three characteristics of multicast transmission? (Choose three.)
- The source address of a multicast transmission is in the range of 224.0.0.0 to 224.0.0.255.
- A single packet can be sent to a group of hosts.
- Multicast transmission can be used by routers to exchange routing information.
- Routers will not forward multicast addresses in the range of 224.0.0.0 to 224.0.0.255.
- Computers use multicast transmission to request IPv4 addresses.
- Multicast messages map lower layer addresses to upper layer addresses.
Explanation: Broadcast messages consist of single packets that are sent to all hosts on a network segment. These types of messages are used to request IPv4 addresses, and map upper layer addresses to lower layer addresses. A multicast transmission is a single packet sent to a group of hosts and is used by routing protocols, such as OSPF and RIPv2, to exchange routes. The address range 224.0.0.0 to 224.0.0.255 is reserved for link-local addresses to reach multicast groups on a local network.
