Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 214

An engineer is concerned with the deployment of a new application that is sensitive to inter-packet delay variance. Which command configures the router to be the destination of jitter measurements?

Answer options

• A. Router(config)# ip sla responder udp-connect 172.29.139.134 5000
• B. Router(config)# ip sla responder tcp-connect 172.29.139.134 5000
• C. Router(config)# ip sla responder udp-echo 172.29.139.134 5000
• D. Router(config)# ip sla responder tcp-echo 172.29.139.134 5000

Correct answer: C

Explanation

The correct answer is C, as the 'ip sla responder udp-echo' command is specifically designed to measure jitter and other latency metrics using UDP echo requests. Options A and B set up connections but do not measure jitter, while option D uses TCP, which is not suitable for jitter measurement in this context.
