The tracert command determines packet loss between a source and a destination.

• A. True
• B. False
• C. It measures jitter
• D. It measures bandwidth

Answer: (B)

Tracert (traceroute) is used to map the path packets take to a destination and to show how long each hop along that path takes. It does this by sending probes with increasing TTL values so each router along the route replies, revealing the hop’s address and the round-trip time to that hop. This gives you a view of the route and the latency at each hop, not an end-to-end measure of how many packets are lost between source and destination. If some probes time out, you might suspect a problem at that hop or that ICMP is being blocked, but that doesn’t provide a reliable packet-loss percentage for the entire path. For actual loss analysis, you’d use other tools (like pathping for hop-by-hop loss or a sustained ping for end-to-end loss). Jitter and bandwidth aren’t what traceroute reports; jitter is latency variability, and bandwidth is throughput capacity, neither of which traceroute directly measures.
