A and C
I don’t see the need for “vCloud Air proxy agent”. What’s this anyway?
You have created vCloud Air Endpoint, but is not connected to Internet.
Then you created Proxy, and assossiate it with the endpointy, which connects you via Internet to vCloud Air. I don’t see D as valid answer.
On another hand, DEM worker requires Internet access, and this is done via vRA Proxy.
