CompTIA Network+ (N10-008) — Question 685

A network engineer installed a new fiber uplink for an office and wants to make sure that the link meets throughput requirements. Which of the following tools should the engineer use to verify that the new link is sufficient?

Answer options

• A. tcpdump
• B. ping
• C. iperf
• D. netstat

Correct answer: C

Explanation

The correct answer is iperf, as it is specifically designed to measure bandwidth and throughput on a network link. Tcpdump is used for packet analysis, ping checks connectivity and latency, while netstat provides information about network connections but does not measure throughput.
