• A. nmap
• B. Wireshark
• C. OTDR
• D. mtr

Answer: (D)

This question tests recognition of a Linux diagnostic tool that continuously combines per-hop latency data with route discovery, updating in real time to show how packets travel toward a destination. The best fit is mtr, also known as My Traceroute, which runs a steady stream of probes to each hop along the path and presents a live table of each hop with round-trip times and any loss. This lets you see both the route to the destination and how different segments are performing, with updates as network conditions change. nmap focuses on scanning hosts and services and doesn’t provide a live, updating traceroute-like view. Wireshark is a packet analyzer for inspecting captured traffic, not a continuous path display. OTDR is an optical testing instrument used in fiber networks to locate faults by sending pulses and analyzing reflections, not a general network path diagnostic tool.
