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 sh

The `inactive timeout 20` command belongs within the `flow monitor` configuration, not the `flow record` configuration which defines what fields to match and collect.

The `flow monitor <name>` configuration block is where caching parameters are set for flexible NetFlow. The `cache timeout inactive 20` command specifically configures the system to export and remove a flow record from the cache if no new packets matching that flow are observed for 20 seconds, effectively fulfilling the requirement to export idle flows.

`cache timeout active 20` specifies that flow records should be exported after 20 seconds regardless of whether they are still active, which is for active flows, not idle flows as required by the question.

Similar to A, `active timeout 20` belongs in the `flow monitor` context, and it sets the timeout for active flows, not for inactive or idle ones as specified in the problem statement.
