Answer - B - Tracert is a tool used in Windows XP systems to determine the route taken by packets across an IP network. Once the routes are known, it is that much easier to pinpoint the exact location where the issue occurs.

Key Takeaway: Tracert works by increasing the “time to live” (TTL) value of each successive packet sent. When a packet passes through a host, the host reduces the TTL value by one and forwards the packet to the next host. When a packet with a TTL of one reaches a host, the host discards the packet and sends an ICMP time exceeded. The output of the tracert command displays the number of hops taken to reach the destination and time taken for each successive hop to reach the destination.
