Did they ask, WCF data services and ADO.NET data services?
If that was the case then both are the same.
WCF Data Services, formerly ADO.NET Data Services(Astoria), and this is a platform for Data Services.

I'm not sure of the answer but what I answered was the communication in WCF happens using XML and/or over a network communication channel. And communication in ADO.NET happens over socket.?
But I'm not at all sure about this. Can someone please tell me the correct answer?
