Question

-A single packet can be sent to a group of hosts. -Multicast transmission can be used by routers to exchange routing information. -The range of to is reserved to reach multicast groups on a local network.

a) IPv4
b) IPv6
c) TCP
d) UDP

Answer 1

The question relates to multicast transmissions which use a reserved range of IPv4 addresses for reaching multicast groups. IPv4 is the correct answer, and it is used alongside UDP, which is often preferred for multicast over TCP.

Step-by-step explanation:

The question pertains to the concept of multicast transmission, which is a method of sending network packets to a group of interested receivers instead of just one. The transmission can be achieved using IPv4 or IPv6 protocols, but the question explicitly refers to a reserved range of IPv4 multicast addresses, which identifies IPv4 as the correct answer. In IPv4, a special range of addresses (224.0.0.0 to 239.255.255.255) is reserved for multicast. Routers can use multicast to exchange routing information and improve the efficiency of data distribution. The protocols generally used with multicast are UDP (User Datagram Protocol) for sending the packets because it allows for multicasting without requiring a back-and-forth communication needed for TCP connections.
