Which protocol measures network performance such as latency and path details?

• A. SNMP
• B. FTP
• C. TWAMP
• D. ICMP

Answer: (C)

TWAMP is designed for active network performance measurement between two endpoints. It runs measurement sessions by exchanging timing packets, which lets you quantify latency (both one-way and round-trip), jitter, and packet loss along the path. The protocol is built specifically to gather precise timing data and other performance metrics across the monitored route, making it well-suited for assessing how the network behaves in real time and identifying where delays or congestion occur.

Other options don’t fit as well: ICMP can tell you basic reachability and a rough round-trip time with ping, but it doesn’t provide structured end-to-end performance metrics or detailed path measurements. SNMP is a management protocol used to poll counters and configurations, not to actively measure performance. FTP is a file transfer protocol without built-in mechanisms for measuring network latency, path details, or other performance characteristics.
