XK0-006 Troubleshooting Practice Question
A system administrator wants to collect network performance statistics over time, including packet loss and latency, to diagnose intermittent connectivity issues. Which tool combines the functionality of ping and traceroute into a single continuous monitoring command?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
mtr
mtr (My TraceRoute) continuously sends packets and displays real-time statistics including loss and latency for each hop, combining ping and traceroute.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
mtr
Why this is correct
mtr continuously combines ping and traceroute by repeatedly probing each hop, refreshing latency and packet-loss statistics in real time. This satisfies the requirement for ongoing monitoring of intermittent connectivity, unlike one-shot ping or traceroute, which capture only a single snapshot and would miss transient faults.
- ✗
tcpdump
Why it's wrong here
tcpdump captures and displays raw packet contents for offline inspection; it neither sends ICMP probes nor reports per-hop round-trip latency. It is the right tool for deep packet-level troubleshooting, such as inspecting payloads or confirming whether traffic actually arrives, but it cannot generate the continuous loss and latency statistics this scenario requires.
- ✗
ss
Why it's wrong here
ss dumps current socket and connection state from the kernel, giving a snapshot of listening ports and established sessions rather than historical loss or latency figures. It suits auditing open ports or diagnosing socket exhaustion, but it sends no probes, so it cannot measure round-trip time or packet loss across a path.
- ✗
netstat
Why it's wrong here
netstat lists active connections, routing entries and interface counters, but its statistics are cumulative counters, not per-target latency or loss measurements over time. It is the right choice for checking which ports are open or which routes exist, yet it cannot probe remote hosts or trace the path hop by hop.
