問題7
You are designing a Windows Presentation Foundation (WPF) application. The WPF application displays indicators to compare your company's past performance to the current day's operationsdata.
The WPF application accesses historic data from your company's data warehouse through a Web service, and accesses current data directly from a Microsoft SQL Server 2008 database.
The WPF application must meet the following requirements:
- Retrieve historic data from the data warehouse at application startup and then once per day.
- Retrieve current data from the database every five minutes, and then update the
indicators.
- Cache all retrieveddata.
- Target the .NET Framework 4 Client Profile.
You need to recommend an approach to data caching.

問題8
You are analyzing an application that uses Microsoft .NET Framework 4 and Microsoft SQL Server 2008.
The application is used to maintain an inventory database and is accessed from several remote Windows client applications. The application frequently updates multiple rows in a database table by using a DbDataAdapter object.
Users report that the application runs slowly during peak business hours.
When large number of records are changed by multiple users, you discover the following:
The CPU utilization of the client applications is normal.
The network utilization increases slightly.
The CPU utilization of the database server remains close to the normal average
for a day.
You need to resolve the performance issue.
