You are designing a Windows Presentation Foundation (WPF) application that will be used
to display real-time data from a Microsoft SQL Server 2008 database. You need to
recommend an approach for displaying the data. Which two actions should you
recommend? (Each correct answer presents part of the solution. Choose two.)
A.
Use a System.Runtime.Caching object in the data layer with a sliding expiration, and
query the database when the Cache object expires.
B.
Implement Oneway binding between the controls in the WPF application and objects in
the data layer.
C.
Implement OneWayToSource binding between the controls in the WPF application and
objects in the data layer.
D.
Use a SqlCacheDependency object in the data layer to query the database when a
change is detected.
