You are an enterprise application developer. You develop an ASP.NETapplication that interacts with a Windows service. The application and the Windows service exchange Microsoft Message Queuing (MSMQ) messages. You need to define an integration test to ensure that the application and the Windows service interact appropriately.
What should you do?

You are an enterprise application developer. You are reviewing the design of a component. The component is used to communicate with a legacy system. The component must meet the following requirements: It must handle high-latency network communications.It must accept synchronous calls from Windows and Web-based applications developed by using .NET Framework 2.0 in the local network.It must use asynchronous communications. You need to implement the design of the component.
What should you do?

You are an enterprise application developer. You are designing a new component to prioritize security requirements and performance. The component contains methods as shown in the following table. Method NameFunctionBuildCompositeInputConsolidates input to the component from other components. BuildPrivateInputInputs data that is private to other component routines. UserInputInputs data from the user.
You need to identify the methods that require run time validation of inputs. You also need to ensure that these methods do not add performance overhead.
Which methods should you use?

You are an enterprise application developer. The data access layer of an application contains the following code segment. (Line numbers are included for reference only.)

01 static public List<Employee> GetEmployees()
{
02 List<Employee> employees = new List<Employee>();
03 using (SqlConnection cnn = new SqlConnection(_cnnStr))
{
04 SqlCommand cmd = new SqlCommand(“GetEmployees”, cnn);
05 cnn.Open();
06 DataSet ds = new DataSet();
07 SqlDataAdapter da = new SqlDataAdapter(cmd);
08 da.Fill(ds);
09 foreach (DataRow row in ds.Tables[0].Rows)
{
10 Employee emp = new Employee();
11 emp.ID = Convert.ToInt32(row[“Id”]);
12 emp.Name = Convert.ToString(row[“Name”]);
13 employees.Add(emp);
14
}
15
}
16 return employees;
17
}

You review the code segment and discover that it takes a long time to execute. You need to modify the code segment to improve the performance.
What should you do?

You are an enterprise application developer. You develop an application by using Microsoft Visual Studio .NET 2005 and .NET Framework 2.0. You are designing a business component that
is used to process sales orders. You need to ensure that the component meets the following requirements: It is available to Windows and Web-based applications on the local network.It uses the most efficient network access protocol.
Which three actions should you perform? (Each correct answer presents part of the solution. Choose three.)

You are an enterprise application developer. You develop an application by using the Microsoft Visual Studio .NET 2005 and the .NET Framework 2.0. The application will be used by financial institutions. Financial institutions can operate checking accounts, savings accounts, and credit cards to customers. Customers can use Automated Teller Machine (ATMs) to manage their accounts.
You need to design a class diagram for the application to meet the following requirements:
* The Checking class must be a type of the BankAccount class.
* The Savings class must be a type of BankAccount class.
* The BankAccount class can be a type of the ATM interface.
* The CreditCard class can be a type of the ATM interface.

Which class diagram should you use?

You are an enterprise application developer. You plan to create a data access component. You need to identify the appropriate collection that meets following requirements: Provides type safety
at design time.Requires minimum development effort.
Which collection should you use?

You are an enterprise application developer. You develop an application to manage products. You plan to expose the products from the application to your business partners. The design solution must meet the following requirements: The service is accessible through firewalls.The service interoperates with client applications that are developed by using different frameworks. You need to ensure that the solution meets the requirements by using the minimum amount of development effort.
What should you do?

You are an enterprise application developer. You are evaluating the physical design of a Windows Forms application. The application will be used on several computers on a corporate intranet. The application connects to different Microsoft SQL Server databases. The application relies on a series of distributed components for the business and data layers. You need to review the database connection strategy to ensure scalability and performance of the application.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

You are an enterprise application developer. You are designing a monitoring mechanism for a serviced component that runs on the company server. The component will be used to execute CPU-intensive operations. When the component is deployed, administrators must be able to monitor the following measures: Number of requests for each operationTime taken for each operation to complete. You need to achieve this goal by using the minimum amount of coding effort.
