Refer to the exhibit. A new management platform has been deployed to collect the flexible NetFlow data based on these requirements: - It must be able to collect BGP next hop, MPLS, and multicast data

The 'source' command specifies the IP address that the router uses to send NetFlow packets, not the destination IP of the collector where they should be sent.

Specifying 'export-protocol netflow-v9' is crucial because NetFlow v9 (and IPFIX) supports advanced fields like BGP next hop, MPLS labels, and multicast data, which are not available in older NetFlow versions like v5.

The 'destination 192.168.4.100' command correctly configures the IP address of the NetFlow collector where the flow data will be sent, directly matching the requirement for the collector's IP.

The requirement explicitly states UDP 9999, so configuring 'transport TCP 9999' is incorrect as it uses the wrong protocol and implicitly defines the port with the transport.

The 'source 192.168.4.4' command specifies an arbitrary source IP address for the NetFlow packets, which does not align with the requirement to send data to 192.168.4.100.
