When you access a server’s properties, the Interoperability tab is not available. What is the most likely cause?

A.
Your Citrix Administrator account has not been granted the Read-Write privilege.

B.
The server farm is in mixed mode.

C.
The server farm is in native mode.

D.
You have not activated any connection licenses.

Explanation:
When the server farm is in native mode, there are no MetaFrame 1.8 servers to communicate with, so the
Interoperability tab is not available.
In mixed mode, this tab is available so that the server can communicate with the ICA browser service.
