The correct answer is A. config flow add monitor AVC_test record ipv4_client_app_flow_record E. config flow add monitor AVC_test exporter Export_to_Prime_Infrastructure. For AVC NetFlow data to be exported from an AireOS controller to Cisco Prime Infrastructure, both a flow record type and an exporter must be explicitly associated with the flow monitor.

Question

Refer to the exhibit. A customer implements AVC on the AireOS controllers. All of the NetFlow data is configured for export to Cisco Prime Infrastructure to be analyzed for a specified period. During testing, no data is reported from the controllers. Which two configurations must be applied for the data to be exported? (Choose two.)

Why each option

For AVC NetFlow data to be exported from an AireOS controller to Cisco Prime Infrastructure, both a flow record type and an exporter must be explicitly associated with the flow monitor.

Aconfig flow add monitor AVC_test record ipv4_client_app_flow_recordCorrect

This command binds the ipv4_client_app_flow_record record template to the AVC_test monitor, defining which IP flow fields are captured; without a record association the monitor has no data schema and collects nothing.

Bconfig flow create exporter Export_to_Prime_Infrastructure 10.20.30.6 port 9991

Port 9991 is the correct NetFlow export port for Cisco Prime Infrastructure, but based on the exhibit the exporter already exists - attempting to create a duplicate exporter with the same name would fail and is not the missing configuration.

Cconfig flow create exporter Export_to_Prime_Infrastructure 10.20.30.6 port 8080

Port 8080 is not the correct NetFlow listener port for Cisco Prime Infrastructure (which uses 9991), making this exporter configuration incorrect regardless of other issues.

Dconfig flow add monitor Export_to_Prime_Infrastructure exporter AVC_test

This command has the monitor name and exporter name reversed - 'Export_to_Prime_Infrastructure' is the exporter, not a monitor name, so this syntax is invalid and would not associate the correct objects.

Econfig flow add monitor AVC_test exporter Export_to_Prime_InfrastructureCorrect

This command links the Export_to_Prime_Infrastructure exporter to the AVC_test monitor, establishing the destination for collected flow data; without this association the monitor captures data but has no export target, so Prime Infrastructure receives nothing.
