DRAG DROP
There is MS Visual Studio 2010 and MS .NET Framework 4 application PassGuideApp.
PassGuideApp is running on a server PassGuideSrv.
PassGuideApp uses this service to connect to a MS SQL Server 2008 database PassGuideDB
located on a separate server PassGuideData.
To access employee data from PassGuideDB ADO.NET Entity Framework is used.
Changes to the data can be made locally, in disconnected mode, on PassGuideSrv, but
when a user of PassGuideApp access PassGuideData, the these local changes data must
be updated with this latest data to PassGuideSrv.
What can ensure this?
Answer: 
Explanation:
The last sentence of the question makes no sense:
‘the these local changes to the data must be updated with this latest data to PassGuideSrv’
WTF? Sounds like something you would get from Google Translate.
Anyway, the choices kind of dictate the answer. You have ClientWins, which implies RefreshMode, which implies Refresh, and you obviously need Context up front, boom there’s your answer.
The only problem is that it doesn’t not agree with that last sentence, but since the sentence makes no sense anyway, I’m sticking with the answer suggested here.
