Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 730

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?

Answer options

• A. flow record recordflow exporter flowexport record recordflow cache timeout active 120 cache timeout inactive 20 cache type immediate
• B. flow monitor monitorflow exporter flowexport record recordflow cache timeout active 120 cache timeout inactive 20 cache type immediate
• C. flow monitor monitorflow exporter recordflow cache timeout active 120 cache timeout inactive 20 cache type permanent
• D. flow record recordflow match ipv6 destination ip-address match ipv6 source ip-address match ipv6 protocol-type view match interface input match interface output match transport destination-port collect counter bytes long

Correct answer: B

Explanation

The correct answer is B because it correctly defines a flow monitor, which is needed to apply the flow record and exporter settings for the specified idle timeout. Options A and D do not utilize a flow monitor, while option C uses an incorrect exporter and a permanent cache type, which does not meet the requirement for idle timeout export.
