Which command can help determine where packets are being dropped in a network?

• A. ping
• B. tracert
• C. nslookup
• D. route

Answer: (B)

The command that can help determine where packets are being dropped in a network is tracert. Tracert, short for trace route, is a network diagnostic tool used to track the pathway that data packets take from one computer to another across an IP network. This command sends out a series of packets with increasing Time to Live (TTL) values to determine the route taken by the packets to reach their destination. As each packet traverses through routers in the network, the TTL value decreases. When it reaches zero, the router sends back an ICMP "time exceeded" message, allowing the originating computer to log the IP address of that router. By doing this iteratively with increasing TTL values, tracert builds a route map that shows each hop along the way to its final destination. If a packet is being dropped, it will typically show up at a specific hop along the path, indicating which router may be failing to forward the packets. This is why tracert is effective for troubleshooting network issues and identifying packet loss locations. The other options do not provide the same level of analysis for packet routes. Ping is primarily used to check the reachability of a host on the network and measures round-trip time but does not provide detailed routing information. Nslookup is
