Which command is used to measure the throughput and latency of traffic between nodes?

• A. traceroute
• B. ping
• C. ifconfig
• D. network test-path

Answer: (D)

Measuring the performance characteristics of the network path between two nodes, specifically throughput and latency, is what the network test-path command is designed to do. It actively probes the link by sending test traffic between the nodes and collects data on how much data can be transferred per second (throughput) and how long responses take (latency). This is essential in a storage environment where replication, snapshot transfer, or quorum communication relies on a predictable, low-latency, high-bandwidth path. Use it to verify the inter-node link meets required performance, identify bottlenecks, and guide tuning or network upgrades. Traceroute shows the route and individual hop delays, not sustained bandwidth. Ping measures round-trip time for small ICMP packets without assessing sustained throughput. Ifconfig reveals interface configuration and statistics, but doesn't perform end-to-end path performance testing. Therefore, network test-path is the appropriate tool for measuring throughput and latency between nodes.
