Which two statements about IPv4 multicast traffic are true? (Choose two.)
IPv4 multicast traffic is a method of sending data from one source to multiple receivers simultaneously. Instead of sending multiple copies of the data to each receiver individually, multicast sends a single copy of the data to a group of receivers who are interested in that data. This method saves network bandwidth and reduces the workload on the source host. Let's examine the given statements:
A. It burdens the source host without affecting remote hosts. This statement is incorrect. Multicast traffic reduces the workload on the source host because it only needs to send a single copy of the data, which is then delivered to all interested receivers in the multicast group. The receivers, on the other hand, may experience increased workload due to the need to process the multicast traffic.
B. It uses a minimum amount of network bandwidth. This statement is generally true. Multicast traffic reduces network bandwidth consumption because it sends a single copy of the data to multiple receivers simultaneously. The network only needs to transmit the data once, instead of transmitting multiple copies of the same data.
C. It is bandwidth-intensive. This statement is incorrect. Multicast traffic is designed to reduce network bandwidth consumption, not increase it. However, multicast traffic can potentially become bandwidth-intensive if the number of receivers in the multicast group is very large, or if the data being sent is large and frequently updated.
D. It simultaneously delivers multiple streams of data. This statement is generally true. Multicast traffic can deliver multiple streams of data simultaneously, allowing multiple applications or services to use the same multicast group.
E. It is the most efficient way to deliver data to multiple receivers. This statement is generally true. Multicast traffic is a very efficient way to deliver data to multiple receivers, especially if the data is large and/or there are many interested receivers. However, there may be situations where unicast or broadcast traffic is more appropriate depending on the requirements of the network and the applications being used.
