Which three components must be defined when configuring Flexible NetFlow?

The correct answer identifies three essential components necessary for configuring Flexible NetFlow in a network environment.

A NetFlow record is a crucial component because it defines the information that will be collected about network flows. This includes specifics such as source and destination IP addresses, ports, and protocols. The data collected in these records is pivotal for network analysis, monitoring, and troubleshooting.

Next, a NetFlow export configuration is needed to specify how flow data will be exported to a collector. This includes configuring the destination, transport protocol, and frequency of data export, ensuring that the collected data is effectively sent to analytics tools for further evaluation.

Finally, a NetFlow monitor ties these components together. It acts as the mechanism to apply the NetFlow record to the traffic, aggregating and managing how the flows are observed and reported.

Together, these three components ensure that network flow data can be effectively recorded, exported, and monitored, which is vital for network management and performance assessment.
