You create Web-based client applications. All Web-based applications are created by using ASP.NET. Larger applications are hosted on Web server farms. The larger applications appear to intermittently lose session state information for users. You need to correct the problem. What should you do?

You create Web-based client applications. You are evaluating the design of an e-commerce Web site. The Web site processes credit card information. The Web site has a shopping cart and expects a high volume of traffic, especially during peak shopping times.

The design specifications for the application must meet the following criteria:

The application will be hosted on a Web farm.
The application will use SSL during the checkout process.
Shopping cart information will be stored in InProc session variables.

You need to evaluate the design of the application and recommend whether it is technically feasible and complete. What should you conclude?

You create Web-based client applications. Your client company has an existing ASP.NET Web-based application. The Web-based application uses a combination of HTML and client-side scripting to deliver online training content. Your client company has asked you to enhance the application to deliver interactive multimedia content. The enhanced application must support dial-up users. You need to recommend an appropriate multimedia delivery mechanism for the application. What should you recommend?

You create Web-based client applications. You are creating a content management system (CMS). You intend to sell CMS to your customers. It is important that customers customize the appearance and behavior of the CMS installation because the system will be used for external Web sites. However, your customers are not programmers. The customers will not be able to modify complicated source code to customize the appearance and behavior of their Web sites. You need to create the system in such a way that customers can modify the appearance and behavior of their Web
sites by editing the minimum number of files, ideally one or two. Which strategy should you use?

You create Web-based client applications. You create an application that is used as a portal. The portal uses a set of custom controls that expose different functionalities.

The set of custom controls includes one control each for the following three tasks:

Track sales
Track inventory
Permit access to the corporate e-mail of the company

The portal must permit users to select the controls that they need to display on the basis of a predefined list.

The design team proposes the following steps to meet the requirement:

Create the custom controls as Web parts.
Create a Web part zone page that has two Web part controls and a catalog part control.
Add the sales Web part control to the Web part zone.

You need to evaluate whether the solution meets the requirements. What should you conclude?

You create Web-based applications. You are creating an Internet banking application. You write the following lines of code to represent a method in your application. (Line numbers are included for reference only.)

01 public void Transfer(decimal amount, BankAccount account) 02 {
03 if (!(amount > 0))
04 throw new Exception(“Invalid deposit amount!”);
05 else
06 {
07 this.Withdraw(amount);
08 account.Deposit(amount);
09 }
10 }

You use the Microsoft Visual Studio 2005 test feature to automatically generate the following unit test.
(Line numbers are included for reference only.)

01 [TestMethod()]
02 public void TransferTest()
03 {
05 BankAccount target = new BankAccount();
06 BankAccount transferTo = new BankAccount();
07 target.Deposit(500);
08 target.Transfer(100,transferTo);
09 Assert.Inconclusive(“A method that does not return a value cannot be verified.”); 10 }

You need to change the test method to return a conclusive result. Which line of code should replace the code on line 09 of the unit test?

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. You are creating a Web site that displays product information for your company.

The application must meet the following requirements:
Support at least 20 concurrent users.
Consume less than 40 percent of the CPU time during peak usage. Process at least five requests per second during peak usage, which is estimated to be between 20 and 30 users.

A Web test is created to verify the requirements by recording how a regular user would interact with the site. Then, based on the Web test, a load test is created. The load test simulates 30 users who execute the Web test simultaneously. You need to decide whether the current strategy is enough to verify the requirements, and recommend changes. What should you recommend?

You create Web-based client applications. You are designing a procedure to retrieve product data from a database. The product data will be displayed on several pages of your Web site. The data will be filtered and sorted by different parameters and will be displayed in grids with paging. Users will not be able to modify the data that is displayed on the Web site. The product data is stored in a database on an instance of Microsoft SQL Server that is located on a different server. The database is configured to support SQL cache invalidation. You need to ensure that the data is retrieved such that the pages of the Web site load as quickly as possible. What should you do?

You create Web-based client applications.

You are creating an intranet application that reviews customer data. The internal Personally Identifiable Information (PII) policy specifies the following requirements for access to customer data:
Only employees in the customer management group can access the customer data. Access to customer data is limited to computers that are inside company facilities.

The legal team advises that you log information that verifies that you have met the PII requirements. The log might be useful if there is a legal challenge over customer privacy. You must create a design that uses minimum amount of storage. You must also ensure that the design meets all the requirements. You decide to store the Microsoft Windows user name for any user who uses the program to access the customer data. You also decide to store the date and time of the access. You need to decide if the design will meet all the requirements. What should you conclude?
