Question
A network engineer is testing the network throughput between Linux servers in a hybrid environment.

Which of the following is the best tool for this task?
Options
- Aiperf
- Btcpdump
- Cnetcat
- Dnetstat

Explanation
iperf (and its successor iperf3) is the standard tool for measuring active network bandwidth and throughput between two endpoints. It operates in a client-server model: one server listens, one client sends, and the tool reports the achievable throughput - exactly what is needed to validate performance against an ISP SLA. tcpdump (B) is a packet capture/analysis tool, not a bandwidth measurement tool. netcat (C) is a general-purpose network utility used for port scanning, data transfer, and debugging - not designed for throughput benchmarking. netstat (D) displays current network connections and statistics but does not actively measure bandwidth.
