What are two types of IPv6 unicast addresses? (Choose two)

Broadcast

Anycast

Loopback

Multicast

Link-local

13.

1 point

What are three characteristics of multicast transmission? (Choose 3)

Multicast transmission can be used by routes to exchange routing information.

A single packet can be sent to a group of hosts.

Computers use multicast transmission to request IPv4 addresses.

The source address of a multicast transmission is in the range of 224.0.0.0 to 224.0.0.255

Multicast messages map lower layer address to upper layer addresses.

The range of 224.0.0.0 to 224.0.0.255 is reserved to reach multicast groups on a local network.
