When you're troubleshooting a network using ping command, What TTL stands for?
- A.
TTL is not a parameter in ping command
- B.
Time to live
- C.
Time to launch
- D.
Translation time loop
Correct Answer
B. Time to liveExplanation
TTL stands for Time to Live. It is a parameter used in the ping command when troubleshooting a network. The TTL value determines the maximum number of hops (routers) that a packet can pass through before being discarded. Each time the packet passes through a router, the TTL value is decremented by one. If the TTL value reaches zero, the packet is discarded. This helps prevent packets from circulating endlessly in the network.Rate this question:
