Explanation:
Detailed explanation-1: -Default route leading to infinite looping sometimes, hence TTL (it restricts the life period of the packet) is used to avoid infinite looping. Hence the correct answer is It can be used to prevent packet looping.
Detailed explanation-2: -Which among the following best explains the use of Time to Live (TTL) field in an IP datagram? Ops: It can be used to prioritize packets It can be used to optimize throughput It can be used to prevent packet looping It can be used to reduce delays A. B. C. D.
