Microsoft UPGRADE MCAD Skills to MCPD Web Developer by Using the Microsoft .NET Framework Set 3

You create Web-based client applications. The application permits users to upload files to a network share. When anonymous users use the upload feature from the Web-based application, a custom error page is displayed. You need to ensure that anonymous users are able to use the application. What should you do?

You are developing an application that will use custom authentication and role-based security. You need to write a code segment to make the runtime assign an unauthenticated principal object to each running thread. Which code segment should you use?

You create Web-based client applications. You identify a reusable software component that you need to use in your application. The component contains functionality to retrieve data from a database. However, the component does not include the functionality to change the color of a table cell when the user moves the mouse cursor into the cell. You need to add the effect of mouse cursor movement to the component in the most efficient way 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 equirements. What should you conclude?

You create Web-based client applications. You are modifying an existing program so that it can be scaled out across a load balanced Web farm. The current design stores session specific data in a session variable. You are required to select an appropriate design. You decide to store the session state in a Microsoft SQL Server database that can be accessed by all the Web servers in the Web farm. You need to evaluate whether the design meets the requirements. What should you conclude?

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 applications. You are creating an Internet banking application. The application will be used by bank account holders. You are creating a method to withdraw money from an account. The method must change the account balance according to one of the following rules: If the amount that is being withdrawn is less than or equal to the account balance, then subtract the amount from the balance. If the amount that is being withdrawn is greater than the account balance by up to 500 dollars, then subtract the amount and a 35-dollar fee from the balance. If the amount that is being withdrawn is greater than the account balance by more than 500 dollars, then generate an error. You are translating the specification given here into pseudo code. You start by writing the following code. You need to insert the correct pseudo code. Which code segment should you insert?

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 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?

You create Web-based client applications. You are writing a code segment that queries the following data from a database: Customer information Order information The code segment does not query the database directly. The code segment calls a stored procedure from the database to perform queries. The stored procedure returns information about a customer based on the customer ID parameter that the code segment provides. The stored procedure accepts the customer ID as an input parameter and includes only one query. The stored procedure returns the result set to the code segment by using output parameters. You need to evaluate whether the stored procedure is designed for best performance and uses the minimum amount of code. What should you conclude?
