An engineer must use flexible NetFlow on a group of switches. To prevent overloading of the flow connector, if the flow is idle for 20 seconds, the flow sample should be exported. Which command set should be applied?

To prevent overloading of the flow connector by exporting an idle flow after 20 seconds, the configuration should establish a flow monitor that utilizes the exporter and record specified. The necessary command set includes the flow monitor, the exporter, and the record flow configuration along with the cache timeout settings. The command 'cache timeout inactive 20' specifies the 20-second idle timeout, and specifying 'cache type immediate' ensures the flow data is exported immediately after the timeout. Therefore, the correct command set is provided in option B.
- Option A is incorrect because it repeats the "record recordflow" command unnecessarily. - Option C is incorrect because it does not include the "flow monitor" command to set up the flexible NetFlow monitor. - Option D is incorrect because it does not include the necessary configuration for exporting flow records based on idle timeout.
Correct
B is correct
This is a sharp turn in the brain, immediate will be derived whether it is 20s or not, permanent is better, but immediate can not be calculated wrong
and besides C missing record configuration
This is a sharp turn in the brain, immediate will be derived whether it is 20s or not, permanent is better, but immediate can not be calculated wrong
All of these seem wrong. Timeout settings are ignored for immediate cache type per the below doc, and answer C doesn't configure a flow record. https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/fnetflow/command/fnf-cr-book/fnf-c1.html#wp3880665773 "The timeout settings have no effect for the immediate cache type."
