How does vCenter communicate with each other ESXi Server?
A.
vCenter periodically polls each ESXi server using a virtual machine port.
B.
A vCenter agent is added to each ESXi server as it is added to the vCenter inventory
C.
vCenter uses a Wake-on-LAN to access the local ESXi services.
D.
vCenter does not communicate directly with an ESXi server, it relies on administrative
involvement.

Can’t find the document in the explanation section. I think the answer is B. http://pubs.vmware.com/vsphere-4-esx-vcenter/index.jsp?topic=/com.vmware.vsphere.intro.doc_41/c_communication_between_virtualcenter_and_esx.html

It could be A. ESXi must be able to send and receive data from every vSphere Client. If you are attaching your ESXi host to vCenter Server, additional ports will be required
It doesn’t ask about management purposes but there needs to be ports open in certain cases.

Gentlemen,
Answer would be B , The vCenter Server agent is installed the first time any host is added to the vCenter Server inventor, & on each managed host, the software that collects, communicates, and executes the actions received from vCenter Server.
Cheers.

I agree the answer would be B.
vCenter Server communicates with the ESX/ESXi host agent through the VMware vSphere API. When you first add a host to vCenter Server, vCenter Server sends a vCenter Server agent to run on the host.
