Which NetFlow component is applied to an interface and collects information about flows?
A. flow monitor
B. flow exporter
C. flow sampler
D. flow collector
Correct Answer: A
Flow monitors are the NetFlow component that is applied to interfaces to perform network traffic monitoring.
Flow monitors consist of a record and a cache. You add the record to the flow monitor after you create the flow monitor. The flow monitor cache is automatically created at the time the flow monitor is applied to the first interface. Flow data is collected from the network traffic during the monitoring process based on the key and nonkey fields in the record, which is configured for the flow monitor and stored in the flow monitor cache.
