NEW QUESTION # 138
Which feature minimizes HOC connections and reduces strain on the vSmart controller m an SO-WAN architecture?

NEW QUESTION # 139
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. on-change subscription
- B. IPFIX
- C. static telemetry
- D. periodic subscription
Answer: A
Explanation:
There are two types of subscriptions: periodic and on-change. With periodic subscription, data is streamed out to the destination at the configured interval. It continuously sends data for the lifetime of that subscription. With on-change, data is published only when a change in the data occurs such as when an interface or OSPF neighbor goes down. https://developer.cisco.com/docs/ios-xe/#!streaming-telemetry-quick-start-guide/streaming-telemetry
