I believe the answer is B and C – you specify a Logical Switch and the DVS Portgroup when you configure the Bridge on the DLR and unless you have defined a Ethernet based firewall rule on the DFW traffic would flow because it is all layer 2. So I cannot understand why A would be correct.

I say B and C is logic. On the Distributed firewall there is a default rule any, any, any, alow so no configuration is required. But the question is required components, the default firewall rule is a required component but also is the Logical Switch (bridge is only supported between VLAN and VXLAN) So you need a Logical Switch. So the question must be: Choose three 🙂
And if I must choose only two, I say B and C.

If “A” is true we should include that option on every question that ask for connectivity. B and C are correct because you should have a Logical Switch to associate with the bridging session.

A has nothing to do with this question. It’s definitely required to have a DLR and Logical switch.
