   An administrator notices that VCF Operations for Networks is reporting a high number of 'dropped packets' on a specific NSX-T segment, but the ESXi host's vSphere performance charts show zero dropped packets on the VM's vNIC. The VCF Operations for Networks collector is deployed as a virtual appliance on a management cluster. What is the most likely reason for this discrepancy?

   • AThe drops are occurring at the distributed firewall or the overlay logical switch, which are not visible in the vNIC counters from the guest OS perspective.
   • BThe drops are caused by the ESXi host's physical NIC being oversubscribed, which is not reflected in the vNIC counters.
   • CThe VCF Operations for Networks collector is misconfigured and is polling the wrong vCenter Server, causing it to report phantom drops.
   • DThe VCF Operations for Networks appliance is running out of disk space and is dropping its own telemetry data, creating false positives.

   A VCF administrator is troubleshooting a network issue where a VM cannot reach a service on the internet. VCF Operations for Networks shows an alert for 'High packet loss' on the Tier-0 gateway's uplink interface. The administrator also sees a vSphere alarm for 'Network connectivity lost' on the ESXi host running the Tier-0 gateway VM. The administrator checks the physical switch and finds that the port connected to the ESXi host is up. What is the most likely root cause?

   • AThe Tier-0 gateway's BGP session to the physical router is down, causing the uplink to report packet loss.
   • BThe physical NIC on the ESXi host is flapping, causing intermittent connectivity on the Tier-0 gateway's uplink.
   • CThe VCF Operations for Networks collector is not receiving data from the Tier-0 gateway, causing a false positive alert.
   • DThe physical switch port is configured with a VLAN mismatch, causing the Tier-0 gateway to drop packets.
