350-401 · Question #1297
Refer to the exhibit. Which configuration completes the collection of flexible NetFlow statistics toward 192.168.0.254 when received on interface Gig0/0?
The correct answer is D. flow monitor NetFlow-Monitor. To complete the collection of Flexible NetFlow statistics on an interface, a flow monitor must be configured and then applied to that specific interface in the direction of interest.

Why each option
To complete the collection of Flexible NetFlow statistics on an interface, a `flow monitor` must be configured and then applied to that specific interface in the direction of interest.
`flow record NetFlow-Record` defines *what* data fields to collect, but it does not initiate the collection or export process.
`flow exporter NetFlow-Exporter` defines *where* to send the collected NetFlow data but does not initiate data collection.
`interface GigabitEthernet0/0` enters interface configuration mode, but the specific command to apply the NetFlow monitor to this interface is missing from this option, and the monitor itself must be defined first.
The `flow monitor` command creates and configures a NetFlow monitor, which ties together the defined `flow record` (what to collect) and `flow exporter` (where to send it). This monitor is then applied to an interface (e.g., `ip flow monitor NetFlow-Monitor input`) to activate data collection.
