Which of the following best describes the purpose of the TTL field in an IP packet?
To limit the number of hops a packet can traverse before being discarded
To determine the priority of a packet in a congested network
To authenticate the source of the packet
To encrypt data payload in the packet for secure transmission
The TTL field in an IP packet limits how many Layer-3 hops the packet can traverse. Each router decrements the TTL by one, and when the value reaches zero, the router discards the packet and typically sends an ICMP Time-Exceeded message. This mechanism prevents packets from looping indefinitely. The other options describe different network mechanisms and do not match the TTL function.
