Hotspot Question
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Each correct selection is worth one point.

Correct Answer:

Explanation:
* TRACERT prints out an ordered list of the routers in the path that returned the ICMP Time Exceeded message.
* Ping, not tracert, determines packet loss.
* Tracert just displays the path to the target, not all connections.
Note
* Example:
tracert 11.1.0.1
Tracing route to 11.1.0.1 over a maximum of 30 hops
1 2 ms 3 ms 2 ms 157.54.48.1
2 75 ms 83 ms 88 ms 11.1.0.67
3 73 ms 79 ms 93 ms 11.1.0.1
Trace complete.
* The TRACERT diagnostic utility determines the route taken to a destination by sending Internet Control Message Protocol (ICMP) echo packets with varying IP Time-To-Live (TTL) values to the destination. Each router along the path is required to decrement the TTL on a packet by at least 1 before forwarding it, so the TTL is effectively a hop count. When the TTL on a packet reaches 0, the router should send an ICMP Time Exceeded message back to the source computer.
