   A VCF administrator is troubleshooting a VM that cannot reach the internet. The VM is in a segment that is connected to a Tier-1 Gateway. The Tier-1 Gateway is connected to a Tier-0 Gateway. The Tier-0 Gateway has a default route to the physical network. The VM can ping other VMs in the same segment, but cannot ping the Tier-1 Gateway's IP address. What is the most likely cause of the issue?

   • AThe VM's default gateway is set to the wrong IP address.
   • BThe Tier-0 Gateway is not advertising the default route to the Tier-1 Gateway.
   • CThe Tier-1 Gateway's routing table is missing a route to the VM's segment.
   • DThe NSX Distributed Firewall is blocking ICMP traffic to the Tier-1 Gateway.

   A VCF administrator notices that a database VM is experiencing high latency on its data disk. The VM is running on a vSAN cluster. vSAN performance metrics show that the disk group is not under capacity pressure, but the 'vSAN backend' latency is high. The VM's storage policy is set to 'RAID-1' with 'Number of failures to tolerate' set to 1. What is the most likely cause of the high latency?

   • AThe VM's storage policy is set to a higher availability level than necessary, causing extra write overhead.
   • BThe vSAN cluster is experiencing a network bottleneck between the ESXi hosts, causing delays in replicating data.
   • CThe VM's SCSI controller is configured for a non-paravirtualized type, causing high CPU overhead in the guest.
   • DThe VM is using a thick-provisioned disk, which is slower than thin-provisioned disks on vSAN.

   A VM in a VCF environment is unable to communicate with a VM on a different segment. Both VMs are in the same NSX Tier-1 Gateway. The administrator has verified that the VMs are in the correct segments and that the Tier-1 Gateway's routing table is correct. What should the administrator check next?

   • AThe NSX Edge Node's load balancer configuration.
   • BThe physical network switches' VLAN configuration.
   • CThe NSX Distributed Firewall rules for the VMs.
   • DThe VM's default gateway settings.
