350-401 Question 213
Single answerYou are tasked to configure Flexible NetFlow (FNF) on a Cisco router to monitor specific traffic patterns in your network. You want to create a flow record that captures source and destination IP addresses, as well as the Layer 4 protocol. After creating the flow record and flow exporter, what is the next step to enable Flexible NetFlow monitoring on the router?
- A
Apply the flow monitor to an interface in the ingress or egress direction.
- B
Enable NetFlow on the global routing process.
- C
Associate the flow record to the flow monitor.
- D
Assign the flow exporter to the interface where monitoring is required.
Show answer and explanation
Correct answer: A
Explanation
To enable Flexible NetFlow monitoring, you must configure a flow record, flow monitor, and flow exporter. Once these components are configured, the flow monitor must be applied to an interface in the ingress or egress direction to activate traffic capture and monitoring. This step ensures that the router collects and analyzes the defined traffic flows.
- A. Correct.
Correct. After creating the flow record, flow monitor, and flow exporter, the flow monitor must be applied to an interface in the ingress or egress direction to start capturing traffic.
- B. Incorrect.
Incorrect. NetFlow is not enabled globally; it is applied to specific interfaces using the flow monitor.
- C. Incorrect.
Incorrect. Associating the flow record to the flow monitor is a required step, but it is done during the flow monitor configuration, not after.
- D. Incorrect.
Incorrect. The flow exporter is part of the flow monitor configuration and does not get directly assigned to an interface.
