You are an enterprise application developer. You are evaluating a component that monitors a Web-based application.
The component stores monitoring information in a database and performs the following functions:

* Retrieves the number of orders placed per second.
* Tracks the data for peak usage of the application and displays the data in a tabular form.

Subsequently, monitoring requirements change in the following manner:

* Users must be able to view data graphically.
* Users must be able to analyze data in real time.
* Users must be able to correlate the number of orders placed per second with the memory usage in the Web server.

You need to evaluate whether the component meets the new requirements and propose a solution, if required.
What should you conclude?

You are an enterprise application developer.
You create an application that has three layers:

* Layer 1 contains the Microsoft Windows client and the input validation logic.
* Layer 2 contains business entities, business workflows, and business rules.
* Layer 3 contains the data access classes and stored procedures.

You need to analyze the layers and identify dependencies that exist between these layers.
Which two dependencies should you identify? (Each correct answer presents part of the solution. Choose two.)

You are an enterprise application developer. You are creating an application. Within your application, an order contains order lines. Order lines are always contained within an order.
You need to analyze this structure and show the link between the order and the order line by using a class diagram.
Which diagram should you choose?

You are an enterprise application developer. You are creating a client/server application. You need to install the application on the company network.
The client/server application must meet the following criteria:

* The server component is a class library that is created by using the .NET Framework.
* The client component is a Microsoft Windows-based application that is created by using the .NET Framework.
* The client component and the server component must communicate by using a binary protocol.
* The fewest possible ports are opened between the client component and the server component.

You need to identify a technology that permits the server to communicate with the client component through the TCP/IP protocol.
Which technology should you use?

You are an enterprise application developer. You are evaluating the physical design of a Web- based application. Fifty customers will use the application from different regions. The use of the application will trigger events of different severities. These events must be logged, extracted, and then filtered on the basis of customer, region, or severity of events. The event details also must be persisted, backed up, and archived for later retrieval. The development team plans to use an event log for logging events. On evaluation, you find the plan does not meet the requirements. You need to explain why an event log fails to meet the requirements.
What should you conclude?

You are an enterprise application developer. You are creating an application that will track shipments. This application must support integration with applications that run on different platforms and operating systems. The application that you are creating can be invoked only through SOAP messages over HTTP. You choose Web services instead of .NET Remoting to meet these requirements. You need to specify the reason for choosing Web services.
Which statement should influence your decision?

You are an enterprise application developer. You are designing an intranet Web application. This application must meet the following requirements:

* The employees must log on to use the application.
* The database authentication mechanism must be as secure as possible.
* The number of connection pools must be minimized.

You decide to use Microsoft SQL Server authentication and a specific SQL Server account. You need to evaluate whether the design will meet the business requirements and make recommendations, if required.
What should you conclude?

You are an enterprise application developer. You are designing an application. The database for the application currently has a one-to-one relationship between order and product. The application must meet the following business requirements:

* An order must contain orders for many products.
* An order must store the ordered quantity of each product.

You need to evaluate the existing design and recommend changes to meet the business requirements.
Which two changes should you recommend? (Each correct answer presents a complete solution. Choose two.)

You are an enterprise application developer. You create a business component for a contact management application that is named Contact. The Contact class contains a public read/write property that is named Company. Company is defined as a string. The Company field in the database is defined as nvarchar(20). You must test whether the property correctly handles values of any length. You decide to use a boundary condition test. You need to evaluate whether the proposed test is appropriate.
What should you conclude?

You are an enterprise application developer. You create an application that consists of a Microsoft Windows service. Your Quality Analysis team finds and reports bugs that occur in the service application. You need to debug your Windows service code to fix the bugs.
