Q57. - (Topic 4) 

You are developing an ASP.NET MVC application that uses forms authentication. The application uses SQL queries that display customer order data. 

You need to prevent all SQL injection attacks against the application. 

How should you secure the queries? 

A. Implement parameterization. 

B. Pattern check the input. 

C. Filter out prohibited words in the input. 

D. Escape single quotes on string-based input parameters. 

Answer: A 

Explanation: With most development platforms, parameterized statements that work with parameters can be used (sometimes called placeholders or bind variables) instead of embedding user input in the statement. A placeholder can only store a value of the given type and not an arbitrary SQL fragment. Hence the SQL injection would simply be treated as a strange (and probably invalid) parameter value.

Q58. - (Topic 4) 

You are developing an application that uses many small images. 

When the images load, the application runs slowly. 

You need to improve the performance of the application. 

What should you do? 

A. Preload all the images when the application starts to ensure that the images are cached. 

B. Convert the images to ICO file format and stream all images on a single connection. 

C. Host all images on a Microsoft Azure web role with multiple instances. 

D. Combine all the images into a single image and use CSS to create sprites. 

Answer: D 

Explanation: Because browsers limit how many concurrent HTTP requests they make to a website, a web page with many small icon images can result in a longer load time. You can combine many small images into a single larger image - a CSS sprite - using the free ASP.NET Sprite and Image Optimization Library available from Microsoft.

Q60. - (Topic 4) 

You are developing an ASP.NET MVC application by using Visual Studio. 

The application throws and handles exceptions when it runs. 

You need to examine the state of the application when exceptions are thrown. 

What should you do? 

A. Add the following code to the web.config file of the application. 

<customErrors mode=”On” > 

<error statusCode=”404” redirect=”CustomErrors.html” /> 

</customErrors> 

B. From the Debug menu in Visual Studio, select Exceptions. Disable the User-unhandled 

check box for Common Language Runtime Exceptions. 

C. Add the following code to the web.config file of the application. 

<customErrors mode=“On” > 

<error statusCode=”500” redirect=”CustomErrors.html” /> 

</customErrors> 

D. From the Debug menu in Visual Studio, select Exceptions. Enable the Thrown check 

box for Common Language Runtime Exceptions. 

Answer: D 

Explanation: Configuring the debugger to break for first chance exceptions 

To change when the debugger breaks, go to Debug->Exceptions… 

When you first open this window you will see that there is a tree grid with one column and checkboxes. 

* 

Break when Thrown. This includes a default list of exceptions known by the debugger, 

grouped by category. 

Note: The possible exceptions that could break from this list is determined by the runtime 

you are debugging. For example, if you are using managed-only debugging then the 

debugger will never break for C++, Win32 Exceptions, etc. even if they are configured to 

break when thrown. 

* 

Checkboxes. If you check the box for a category, then the debugger will break for all First 

Chance Exceptions while debugging. If you don’t want to enable all First Chance 

Exceptions, you can find the specific exception types that you wish to configure by using 

the search box.
