Which option must be configured on a target device to use time stamping to accurately represent response times using IP SLA?
Answer A.
I agree too.
The IP SLAs Responder is a component embedded in the destination Cisco routing device that allows the
system to anticipate and respond to IP SLAs request packets. The IP SLAs Responder provides an enormous
advantage with accurate measurements without the need for dedicated probes and additional statistics not
available via standard ICMP-based measurements.

Agree
Correct answer is A
Correct Answer: A
When the IP SLAs responder is enabled, it allows the target device to take time stamps when the packet arrives on the interface at interrupt level and again just as it is leaving, eliminating the processing time. This time stamping is made with a granularity of sub-milliseconds (ms).
