   A VCF administrator is troubleshooting an application performance issue reported by users of a VM running on an NSX-T segment. The VM's vNIC shows no drops or errors, and the ESXi host reports no physical NIC errors. Using VCF Operations for Networks, the administrator opens the flow analytics for the VM's IP address and sees the flow between the VM and the database server shows high latency and a small number of retransmissions. What is the most appropriate next step in the troubleshooting workflow?

   • ACheck the flow path and examine the latency and drop statistics on each network element along the path between the VM and the database server.
   • BReview the ESXi host's vSwitch uplink configuration to verify the physical NIC teaming policy is set to Route based on originating virtual port.
   • CReboot the application VM to clear any potential TCP stack issues causing the retransmissions.
   • DImmediately disable the NSX-T distributed firewall rule between the VM and the database server to rule out policy drops.

   A VCF administrator is troubleshooting a network issue where a VM cannot reach 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. What is the most likely root cause?

   • AThe physical uplink connected to the Tier-0 gateway's uplink interface is down or flapping, causing packet loss and the vSphere alarm.
   • BThe Tier-0 gateway's BGP session to the physical router is down, causing the uplink interface to report packet loss.
   • CThe VM's NSX-T distributed firewall is blocking all outbound traffic, causing the packet loss on the Tier-0 uplink.
   • DThe VCF Operations for Networks collector is not receiving data from the Tier-0 gateway, causing a false positive alert.
