A user is executing a tracert to a remote device. At what point would a router, which is in the path to the destination device, stop forwarding the packet?
- when the values of both the Echo Request and Echo Reply messages reach zero
- when the value in the TTL field reaches zero
- when the router receives an ICMP Time Exceeded message
- when the host responds with an ICMP Echo Reply message
- when the RTT value reaches zero
| Explanation:
When a router receives a traceroute packet, the value in the TTL field is decremented by 1. When the value in the field reaches zero, the receiving router will not forward the packet, and will send an ICMP Time Exceeded message back to the source. |
