You are an enterprise application developer. You are designing an event logging mechanism for a Web service. The Web service will be hosted on a Web farm. Your company policy specifies that all events for a component must be stored in a secure location. You need to design the event logging storage strategy to comply with the company policy.
Which storage mechanism should you use?

You are an enterprise application developer. An ASP.NET application accesses a Microsoft SQL Server database. You discover that the application intermittently logs the following exception:
“System.InvalidOperationException: Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.”
You need to identify an appropriate performance counter to ascertain that the exception is caused by the leaking connections.
Which performance counter should you monitor?

You are an enterprise application developer. You are modifying an existing component that communicates with a single vendor. You need to ensure that the design meets the following requirements:
* Supports multiple vendors.
* Supports common business rules that are applicable to all vendors.
* Supports rules that are specific to each vendor.Supports addition of new vendors easily.

What should you do?

You are an enterprise application developer. You are developing a Web service. The service will be consumed by client applications that are built on the .NET and other platforms. The Web service will return a collection to the client applications. You need to ensure that the client applications can consume the collection. You want to achieve this goal by using the minimum amount of development effort.
What should you do?

You are an enterprise application developer. You have created an ASP.NET application. You need to create a unit test to test the Button1_Click event handler of an aspx page by using the minimum amount of code.
What should you do?

You are an enterprise application developer. You plan to evaluate the performance of an ASP.NET application. You review a performance monitoring log. You notice that the ASP.NET Worker Process Restarts performance counter shows a consistent measure over several days. However, the performance counter spikes unexpectedly at irregular intervals. You need to provide the following information: An explanation for the performance spike.A plan to ensure that the performance spike does not recur.
What should you do?

You are an enterprise application developer. You are developing an application that runs in an N- tier environment. You need to design your N-tier layers to enforce client-based certificate security.

How should you complete the diagram? (To answer, drag the appropriate layers to the correct locations in the answer area.)

You are an enterprise application developer. You are designing a component that will perform the following tasks: Read data from a transaction that accesses multiple data sources.Display a computed result to the user. The component contains the following routines: A routine that displays the returned dataA routine that retrieves the transacted data You want data to be displayed only when the results are complete. You need to design the component to use the threading architecture to optimize performance and to minimize the usage of resources. What should you do?

You are an enterprise application developer. You create an ASP.NET application that calls a .NET remoting object named TradingEngine. The object implements an interface named ITradingEngine. This interface defines a method that returns a SecurityDataTable object. The application types are partitioned into assemblies in the following manner: The TradingEngine class is implemented in an assembly named TradingEngineLib.The ITradingEngine interface is implemented in an assembly named TradingEngineInterfaceLib.The SecurityDataTable class is implemented in an assembly named TradingEntities. You need to identify the minimum set of assemblies necessary for deployment in the ASP.NET application.
Which assembly/assemblies should you include?

You are an enterprise application developer. You develop an application for a food store subsidiary of a company named Contoso, Ltd. The application contains the following components: ASP.NET applicationBusiness entitiesBusiness componentsData access layerLoggingData access helper The application design must meet the following requirements:
Use an N-tier environment.
Use components that can be reused
Use assembly names that map to the first three sections of the namespaces.

You need to identify the structure of the namespaces.
Which namespace structure should you use?
