You are redesigning an existing three-tier ASP.NET Web application that is deployed to a
Web server, an application server, and a database server that runs Microsoft SQL Server
2008. Usage has increased significantly. The application has become slow and occasionally
times out. Health monitoring logs indicate that the data access logic on the application
server is consuming the majority of the CPU resources. You need to recommend an
approach for addressing the scalability and reliability issues. Which two actions should you
recommend? (Each correct answer presents part of the solution. Choose two.)

A.
Partition the tables and indexes in the database.

B.
Use a clustered database server configuration.

C.
Move the application tier to a Web farm.

D.
Move the Web tier to a Web farm.
