Explanation
The configuration in chosen option is the most comprehensive and includes the required components for monitoring traffic issues using NetFlow. Here's why: 1. ip flow-export destination: Specifies the NetFlow collector's IP and port where the flow data is 2. ip flow-export source: Sets the source IP for NetFlow exports, typically a loopback interface for 3. ip flow-export version 9: Configures NetFlow to use version 9, which supports templates for flexible flow reporting. 4. ip flow-cache timeout active and inactive: Sets timeouts for active and inactive flows to ensure timely updates and reduce stale entries. 5. snmp-server ifindex persist: Maintains interface index persistency for monitoring and troubleshooting. 6. ip flow ingress: Enables NetFlow monitoring for inbound traffic on the problematic interface (TenGigE 0/0/0/1).
