   What is the role of a dvPort group in a vSphere Distributed Switch?

   • AIt defines the physical uplink capacity for the switch.
   • BIt manages the host's physical network adapters.

   A VM on a distributed port group is unable to communicate with any other device on the network. The VM's IP configuration is correct, and the VM can ping its default gateway. The VDS uplink status shows 'Down' for all uplinks. What is the most likely cause of the issue?

   • AThe VDS teaming policy is misconfigured.
   • BThe VM's virtual NIC is not connected.
   • CThe dvPort group VLAN ID is incorrect.
   • DThe physical switch ports connected to the host are down.

   Users report intermittent slow performance for VMs on a single ESXi host. The VMs are connected to a VDS with two 10GbE uplinks. Monitoring shows high packet loss and latency on the VMs, but the physical switch ports and uplinks show no errors. The VDS teaming policy is 'Route based on IP hash'. What should the administrator check first?

   • AChange the teaming policy to 'Route based on physical NIC load'.
   • BCheck the VDS health check status for the teaming policy.
   • CReview the vmkernel logs for dropped packets on the uplinks.
   • DVerify that the physical switch ports are configured in an EtherChannel/LACP bundle.
