   An engineer configured NetFlow on an IOS XR router to export flows to a collector at 203.0.113.10 port 2055. The 'show flow exporter-map' output shows the exporter is configured correctly, but the collector is not receiving any flows. The engineer suspects a sampling configuration issue. Which action should the engineer take to verify and resolve the problem?

   • ACheck the flow monitor map for a sampling configuration and verify that the sampler is applied to the interface.
   • BCheck the flow record map to ensure the correct fields are matched.
   • CReboot the router to clear any stale flow cache entries.
   • DVerify that the collector is reachable via ping from the router.
