You create Web-based client applications. You are creating an online reporting application that must generate inventory restocking reports within 34 seconds. In the development
environment, during a unit test, generation of the month-end report took 42 seconds. You need to recommend what action must be taken to validate the test results. What should you recommend?

You create Web-based client applications. You are creating an application for a Web site. The Web site uses the application to simulate mortgage loans. Your application calculates the monthly payment for loans. The monthly payment is based on the number of payments, rate, and the amount of loan. You need to create the unit testing strategy for the application. What should you do?

You create Web-based client applications. You create an application that will be used by customers to browse the product catalog of an Internet-based store and buy products.

The application must meet the following requirements:

Permit registered customers of the store to change display settings and personal information. Store the updated information and associate the information with the logged-on customer.

You need to choose appropriate technologies to meet these requirements. Which two technologies should you choose? (Each correct answer presents part of the solution. Choose two.)

You create Web-based client applications. You are creating a component that sends the data that is generated by regional offices to a remote server that is located at the central office. Each regional office generates thousands of orders every week. This data is stored on several tables in an instance of Microsoft SQL Server that is located at the regional office. The manager at the regional office reviews all orders and modifies them, if necessary, before inserting them into the database at the central office.

You need to ensure that the component meets the following requirements:

The manager has the option of reviewing and modifying the orders offline. The data from a regional office is copied to the server that is located at the central office in as short a time as possible.

Which option should you use?

You create Web-based client applications. You are reviewing a Web application page that populates a list of all employees of your company. You analyze code and find that the Web application page does not prevent exceptions from traveling to the browser. You need to ensure that the Web application page intercepts exceptions and presents an error message to the browser. What change should you suggest?

You create Web-based client applications. Your company has an existing ASP.NET application that is currently deployed on a single server. The application manages state by using session variables and ViewState. The number of users for the application has significantly increased. You need to configure the application to accommodate the significantly increased traffic and to recover transparently from hardware failure. Which three actions should you perform? (Each correct answer presents part of the solution. Choose three.)

You create Web-based client applications. You are evaluating an application. The application displays data that is stored in XML files. The data changes periodically. The development team implements a complex caching solution to improve the performance of the application. However, the caching solution is identified as causing the performance of the application to drop to an unacceptable level. The caching solution also results in significant data latency. The application requirements state that the data that is displayed in the application must be close to real time. You need to ensure that the application design meets the requirements. You also need to ensure that least amount of code is used. Which rationale should you choose?

You create Web-based client applications. You review an application that manages the medical information of patients. The information is confidential and needs to be stored by using the most secure method available.
The application encrypts patient data and stores it in database tables. The application stores a document or image that is related to a patient in the following manner:

The name of the item is stored in the database.
The physical document or image is stored in the local file system.

The application locates and retrieves the physical document or image based on the name that is returned from the database when the data for a patient is queried. You need to evaluate whether the current application design uses the most secure method available to store information and provide an appropriate recommendation. What should you recommend?

You create Web-based client applications. You administer a large ASP.NET Web application that is hosted by using IIS.

The application must meet the following requirements:

Permit all users to log on by using a Web page that is integrated into the application. The security configuration must accommodate the largest number of browsers possible.

You need to make recommendations for a security plan that meets the application requirements. What should you recommend?

You create Web-based client applications. You are designing a new Web site for your company. You need to evaluate the design concept for the main page, default.aspx. The default.aspx page contains static information, except for one data grid that displays information about the companys products. The data grid will retrieve the data from a component. The component will retrieve the data from a stored procedure. The page has the appropriate permissions to the Microsoft SQL Server database.

The application design must achieve the following goals without altering the data component:

The default.aspx page must load quickly.
The default.aspx page must contain the latest data from the database.

You decide to use a sqlCacheDependency attribute to ensure that the default.aspx page always displays the latest data in the grid. You need to ascertain whether the use of the sqlCacheDependency attribute
meets the requirements of this application. Which rationale should you choose?
