An infrastructure team is concerned about the shared memory utilization of a device, and for this reason, they need to monitor the device state. Which solution limits impact on the device and provides the required data?
A. IPFIX
B. static telemetry
C. on-change subscription
D. periodic subscription
Wrong!
IPFIX is the successor of Netflow and used for traffic information.
I guess the right answer is C since information is not requested periodically and send only when something happend.
