350-401 Question 216
Single answerYou are tasked with monitoring traffic patterns on a network by using Cisco Flexible NetFlow. You want to create a customized flow record to track source and destination IP addresses, protocol, and TCP port numbers. After defining the flow record, what is the next step to ensure the NetFlow configuration works correctly?
- A
Apply the flow record to an interface directly.
- B
Define a flow exporter and link it to the flow record.
- C
Create a flow monitor and attach it to the flow record.
- D
Configure the NetFlow collector IP address in the flow record.
Show answer and explanation
Correct answer: C
Explanation
After defining a flow record in Flexible NetFlow, the next step is to create a flow monitor and link it to the flow record. The flow monitor serves as a container that holds the flow record and an optional flow exporter. The flow monitor is then applied to an interface to begin capturing and analyzing traffic. Without creating and attaching the flow monitor, the NetFlow configuration will not function as intended.
- A. Incorrect.
This is incorrect because flow records cannot be applied directly to an interface in Cisco Flexible NetFlow. They must first be associated with a flow monitor.
- B. Incorrect.
This is incorrect because while a flow exporter is used to export flow data to a collector, it is not the immediate next step after defining a flow record. A flow monitor must be created and associated with the record first.
- C. Correct.
This is correct because a flow monitor must be created and linked to the flow record. The flow monitor is then applied to an interface for tracking traffic.
- D. Incorrect.
This is incorrect because the NetFlow collector IP address is configured in the flow exporter, not the flow record itself. A flow monitor is the immediate next step.
