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?

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

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

Correct Answer: B

Tcp-connect involves establishing a full connection whereas udp-echo echo is used to measure response times and test end-to-end connectivity.
