High bandwidth utilization is occurring on interface Gig0/1 of a router. An engineer must identify the flows that are consuming the most bandwidth. Cisco DNA Center isused as a flow exporter and is configured with the IP address 192.168.23.1 and UDP port 23000. Which configuration must be applied to set NetFlow data export and capture on the router?
Correct Answer: D
The correct configuration for setting NetFlow data export and capture on the router involves specifying the version of flow-export, setting the destination IP address and UDP port, selecting the interface, and enabling both ingress and egress flow capture. This is exactly what is done in Option D. It starts with specifying that IP flow-export version 9 should be used. Then it sets the destination for flow data export to IP address
192.168.23.1 on UDP port 23000, which matches the Cisco DNA Center configuration mentioned in the question. After that, it selects interface Gig0/1 and enables both ingress and egress IP flow capture on this interface.
