New Microsoft 70-486 Exam Dumps Collection (Question 6 - Question 15)

Q6. You are developing an ASP.NET application that allows users to download Microsoft Azure log files. You need to improve the performance of the application.

What should you do?

A. Minify the content files.

B. Enable compression in IIS.

C. Bundle the content files into a single .tar file.

D. Host the image, JavaScript, and CSS files on a different server.

Answer: C

Explanation:

Bundling is a new feature in ASP.NET 4.5 that makes it easy to combine or bundle multiple files into a single file. You can create CSS, JavaScript and other bundles. Fewer files means fewer HTTP requests and that can improve first page load performance.

Q7. You are developing an ASP.NET MVC application that supports multiple cultures and multiple languages. The application will be sold to international customers.

The ASP.NET MVC application must store localized content in satellite assemblies for multiple languages.

You need to generate the satellite assemblies during an automated build. Which tool should you use?

A. Gacutil.exe

B. Al.exe

C. Ildasm.exe

D. nasm.exe

Answer: B

Explanation:

Use the Assembly Linker (Al.exe) to compile .resources files into satellite assemblies. Al.exe creates an assembly from the .resources files that you specify. By definition, satellite assemblies can only contain resources. They cannot contain any executable code.

The following Al.exe command creates a satellite assembly for the application MyApp from the file strings.de.resources.

C. IClientValidatable

D. IResultFilter

Answer: A

Explanation:

Exception filters are used to apply global policies to unhandled exceptions in the MVC app. Exception Filters implement either the IExceptionFilter or IAsyncExceptionFilter interface. Exception filters handle unhandled exceptions, including those that occur during controller creation and model binding. They are only called when an exception occurs in the pipeline.

Q13. You are designing a distributed application.

The application must store secure information that is specific to an individual user. The data must be automatically purged when the user logs off.

You need to save transient information in a secure data store. Which data store should you use?

A. Session state

B. Database storage

C. Profile properties

D. Application state

Answer: A

Explanation:

ASP.NET session state enables you to store and retrieve values for a user as the user navigates ASP.NET pages in a Web application. HTTP is a stateless protocol. This means that a Web server treats each HTTP request for a page as an independent request. The server retains no knowledge of variable values that were used during previous requests.

ASP.NET session state identifies requests from the same browser during a limited time window as a session, and provides a way to persist variable values for the duration of that session.
