Q
Two machines can use the timestamp request and timestamp replay messages to determine the ___________ needed for an IP datagram to travel between them.
AA. Half-trip time
BB. Round-trip time
CC. Travel time for the next router
DD. Time to reach the destination/source
Correct Answer:
B. B. Round-trip time
Explanation:
The round-trip time refers to the total time taken combining the time taken for a packet sent from a source to reach a destination and the time taken the acknowledgement sent by the destination to reach the source. The Router sends destination unreachable message if the destination is not found.
