Which Linux utility is designed to show the path a packet takes and can be used by non-superuser accounts, acting similarly to traceroute?

Which Linux utility is designed to show the path a packet takes and can be used by non-superuser accounts, acting similarly to traceroute?

• A. tracepath
• B. traceroute
• C. ipconfig
• D. ifconfig

Answer: (A)

The main idea is discovering the route that packets follow to a destination by sending probe packets with gradually increasing time-to-live values and listening for the replies from routers along the path. This lets you map each hop from your machine to the destination. Tracepath is the Linux utility designed for this purpose and it’s made to be usable by non‑superuser accounts. It uses the system’s normal networking facilities to send the probes and report each hop, giving you a straightforward view of the path without needing elevated privileges. That makes it especially convenient for quick diagnostics by regular users. Traceroute also performs path discovery, but tracepath is specifically noted for working without root privileges on many Linux systems, which is why it’s the fitting choice for a non‑root user in this context. The other two options don’t fit the goal: ipconfig and ifconfig are about showing or configuring network interfaces rather than mapping the route packets take.
