350-401 Question 215
Select 4You are tasked with configuring Flexible NetFlow on a Cisco router to monitor network traffic. The configuration requires you to create a flow record to capture source and destination IP addresses, along with the protocol type. Which of the following steps must be completed to successfully configure Flexible NetFlow?
- A
Define a flow record and specify the required fields such as source and destination IP addresses and protocol.
- B
Apply the flow monitor to an interface in the input or output direction.
- C
Configure a flow exporter to send the data to a collector.
- D
Enable NetFlow on the router globally using the 'netflow enable' command.
- E
Define a flow monitor and associate it with the configured flow record.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
To configure Flexible NetFlow, you need to define a flow record to specify the fields to capture, create a flow monitor to associate the flow record and optionally a flow exporter, and apply the monitor to an interface. The 'netflow enable' command is not valid; instead, Flexible NetFlow is applied at the interface level through the flow monitor.
- A. Correct.
Correct. A flow record is required to define the specific fields that should be captured, such as source and destination IP addresses and protocol.
- B. Correct.
Correct. The flow monitor must be applied to an interface to collect data in the input or output direction.
- C. Correct.
Correct. Configuring a flow exporter is necessary to send the collected flow records to an external collector for analysis.
- D. Incorrect.
Incorrect. There is no 'netflow enable' command for enabling NetFlow globally. Flexible NetFlow is configured at the interface level by applying the flow monitor.
- E. Correct.
Correct. A flow monitor must be defined to tie together the flow record and exporter, and it is applied to an interface for traffic monitoring.
