Suggested answer: A

Explanation:

Understanding Tracert:

tracert (Traceroute in Windows) is a command-line tool used to trace the path that packets take from the source to the destination. It records the route (the specific gateways at each hop) and measures transit delays of packets across an IP network.

Output Analysis:

The output shows a series of IP addresses with corresponding round-trip times (RTTs) in milliseconds.

The asterisks (*) indicate that no response was received from those hops, which is typical for routers or firewalls that block ICMP packets used by tracert.

Comparison with Other Tools:

netstat: Displays network connections, routing tables, interface statistics, and more, but does not trace packet routes.

tcpdump: Captures network packets for analysis, used for detailed network traffic inspection.

nmap: A network scanning tool used to discover hosts and services on a network, not for tracing packet routes.

Usage:

tracert helps identify the path to a destination and locate points of failure or congestion in the network.
