SK0-004 · Question #352

An administrator thinks that a particular network connection is dropping packets. Which of the following tools would the administrator use to BEST identify where the packets are being dropped?

The correct answer is A. tracert. tracert (traceroute) maps the hop-by-hop path packets travel and reveals which router or link is dropping or delaying them.

Why each option

tracert (traceroute) maps the hop-by-hop path packets travel and reveals which router or link is dropping or delaying them.

AtracertCorrect

tracert sends packets with incrementing TTL values to discover each router hop along the path to a destination. When a hop stops responding or shows 100% packet loss, the administrator can pinpoint exactly where on the network the drops are occurring, which ping alone cannot provide.

Bping

ping tests end-to-end reachability and round-trip time to a single target but does not reveal which intermediate hop is responsible for packet loss.

Cnslookup

nslookup queries DNS name resolution and has no capability to trace or analyze network routing paths.

Dnetstat

netstat displays active TCP/UDP connections and socket statistics on the local machine and cannot identify remote routing or packet-drop locations.
