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
✓
iperf
Options A and C are correct. iperf is a tool used to measure network throughput between two hosts. Traceroute diagnoses network path and latency, which can help identify performance bottlenecks. Options B, D, and E are incorrect: tcpdump captures packets but does not measure throughput; nslookup is a DNS lookup tool that does not measure network performance; ping measures latency but not throughput.
