Question 817 - 350-401 discussion

Option A is the correct configuration to set NetFlow data export and capture on the router. This option enables NetFlow data export to the Cisco DNA Center with the IP address 192.168.23.1 and UDP port 23000, and also enables the ip flow-top-talkers command on the interface Gig0/1.The ip flow-top-talkers command displays the top talkers (the source and destination pairs that are consuming the most bandwidth) on the interface, based on the NetFlow statistics collected by the router12.

Option B is incorrect because it does not enable the ip flow-top-talkers command on the interface Gig0/1, which is required to identify the flows that are consuming the most bandwidth.The collect counter bytes command is used to specify the fields to be collected by Flexible NetFlow, which is a different feature from NetFlow3.

Option C is incorrect because it does not specify the UDP port for the NetFlow data export destination, which is required to send the NetFlow packets to the Cisco DNA Center.The default UDP port for NetFlow is 9996, which does not match the port configured on the Cisco DNA Center4.

Option D is incorrect because it does not enable NetFlow data export on the router, which is required to send the NetFlow statistics to the Cisco DNA Center.The ip flow-export source command is used to specify the source IP address of the NetFlow packets, but it does not enable the NetFlow data export feature4.Reference:1:ip flow-top-talkers,2:Capture NetFlow data,3:collect counter bytes,4:ip flow-export destination
