The correct answer is D. The virtual machine will fail to communicate externally. A vSwitch1 configuration with no active uplinks assigned to the port group leaves the virtual machine with no physical path for external traffic.

Why each option

A vSwitch1 configuration with no active uplinks assigned to the port group leaves the virtual machine with no physical path for external traffic.

AThe virtual machine will communicate on both uplinks

Traffic cannot traverse both uplinks if neither is set as an active uplink in the NIC teaming policy shown in the exhibit.

BThe virtual machine will only communicate on vmnic1

vmnic1 cannot carry traffic if it is not designated as an active uplink in the port group or vSwitch configuration shown.

CThe virtual machine will only communicate on vmnic2

vmnic2 cannot carry traffic if it is not designated as an active uplink in the port group or vSwitch configuration shown.

DThe virtual machine will fail to communicate externallyCorrect

Based on the exhibit, the port group or vSwitch NIC teaming policy has both vmnic1 and vmnic2 configured as unused or in a state that removes them from active duty for this port group. Without at least one active uplink, frames destined for external networks have no physical NIC to exit through, causing complete external communication failure.
