   A network team needs to monitor both inbound and outbound traffic on a router interface to analyze asymmetric traffic patterns. They have created one flow record and one flow exporter. How should they configure flow monitors to achieve this?

   • ACreate two flow records, one for ingress and one for egress, and apply them to the interface with the same exporter.
   • BCreate two flow monitors, each referencing the same record and exporter, and apply one to ingress and one to egress on the interface.
   • CApply the flow monitor to the interface in the 'both' direction using the 'ip flow monitor both' command.
   • DCreate a single flow monitor and apply it to both ingress and egress simultaneously on the interface.
