Q
In Multicast Routing Protocol, flooding is used to broadcast packets but it creates ________
AA. Gaps
BB. Loops
CC. Holes
DD. Links
Correct Answer:
B. B. Loops
Explanation:
In multicast routing, there is one sender and many receivers. So flooding is the most basic method to forward packets to many receivers. The one issue with flooding is that it creates routing loops. One loop prevention method is that the routers will not send the packet to a node where the packet has been received before.
