Question
A network is being migrated from IPV4 to IPV6 using a dual-stack approach. Network management is already 100% IPV6 enabled. In a dual-stack network with two dual-stack NetFlow collections, how many flow exporters are needed per network device in the flexible NetFlow configuration?

Why each option
This question determines the number of Flexible NetFlow exporters required per device in a dual-stack network with two dual-stack NetFlow collectors.
One exporter would only send flows to a single collector, not the two specified dual-stack collections.
In a dual-stack environment with two dual-stack NetFlow collections, each network device requires two flow exporters. Each exporter is configured to send flows to one of the dual-stack collectors, capable of receiving both IPv4 and IPv6 flow data.
Four exporters would be required if separate exporters were needed for IPv4 and IPv6 traffic to *each* of the two collectors, which is not typical for dual-stack capable collectors.
Eight exporters is excessive and unnecessary for the described scenario of sending flows to two dual-stack collectors.
