A new virtual machine cannot reach its default gateway.
-The vSphere administrator checks that the virtual machine’s vmnic is connected to the correct portgroup, and
that the portgroup is on the correct virtual switch
-This is the only virtual machine on this portgroup
-Other virtual machines that are on the host and connected to the same Distributed switch are running as
normal
-The Distributed Switch has only one uplink
Which could be the cause of this issue?
A.
Block All Ports has been selected on the Distributed Switch.
B.
The wrong VLAN ID has been added to the portgroup.
C.
The VLAN has not been configured in virtual machine hardware settings.
D.
The physical adapter is down.

If you cannot successfully ping your default gateway’s IP address, verify that your default gateway is connected to the network and functioning properly and that ESX Virtual Switch configurations are in compliance.

‘D’ cannot be the right answer. In the question it says there’s only one uplink and all other VMs connected to *other* portgroups are running fine (i.e. they can communicate with external network). If the physical adapter was down, no VMs, no matter to what portgroup(s) they are connected, would be able to do so.
That means ‘B’ is correct.
