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. What should you do?

You are an enterprise application developer. You create an application that consists of a data access component and a business component. The business component calls the data access component to persist business objects. The Quality Analysis team tests both components and finds errors in the data access component. These errors result in retrieval of wrong data. You need to reduce the errors in your code before the components are retested by the Quality Analysis team. What should you do?

You are an enterprise application developer. Your team has created a distributed application that permits users to generate reports. The reports aggregate data from existing databases. You must move your new application into a test environment. You propose the following criteria:

Compile the application components in release mode.
Publish the ASP.NET files to the test Web server.
Install the serviced components in component services on the application server. Backup the development database and restore it on the test database server.

You need to evaluate the proposal and recommend accordingly. What should you recommend?

You are an enterprise application developer. You are designing unit test cases for an account management system of a regional bank. Before creating the application, you create the unit test scenarios by using use cases. Three high-level use cases are outlined as shown in the following exhibit.

You need to write unit tests to test the functionality inside the system. Which three sets of unit tests should you write? (Each correct answer presents part of the solution. Choose three.)

You are an enterprise application developer. You create a Web service that wraps a business component to expose it through the Web. The business component contains two classes, the Utility class and the Facade class. The Utility class has private methods and internal methods. The Facade class has public methods. The Web service component has a Web service class that is named Services. The Services class performs security verification before the functions in the business component are called. The Services class relies on a class that is named Security in the Web service to implement the security verification. You have completed unit testing both components. You need to choose the class for which to write test cases for integration testing.
Which class should you choose?
