New Microsoft 70-486 Exam Dumps Collection (Question 5 - Question 14)
Q5. You are developing an ASP.NET MVC application that uses forms authentication. The user
database contains a user named OrderAdmin. You have the following requirements:
You need to implement the controller to meet the requirements.
Which code segment should you use? (Each correct answer presents a complete solution. Choose all that apply.)
A. Option A
B. Option B
C. Option C
D. Option D
Answer: B
Explanation:
With MVC4 a new attribute has been introduced, namely the [AllowAnonymous] attribute. Together with the [Authorize] attribute, you can now take a white-list approach instead. The white-list approach is accomplished by dressing the entire controller with the [Authorize] attribute, to force authorization for all actions within that controller. You can then dress specific actions, that shouldn't require authorization, with the [AllowAnonymous] attribute, and thereby white-listing only those actions. With this approach, you can be confident that you don't, by accident, forget to dress an action with the [Authorize], leaving it available to anyone, even though it shouldn't.

Q6. You are developing an Azure worker role. You enable crash dump collection for the role. When the role starts, an external application stops responding.
You need to download the crash dump to determine why the application stops responding.
From which two locations can you download the crash dump? Each correct answer presents a complete solution.
A. Azure Blob storage
B. the temp folder on the virtual machine that is running the role instance
C. Azure file storage
D. the DiagnosticStore local resource folder on the virtual machine that is running the role instance
Answer: A,D
Explanation:
When you enable collection of crash dumps, the resulting data is written to the
CrashDumps directory in the DiagnosticStore local resource that is automatically configured for your role.
When crash dump data is transferred to persistent storage, it is stored to the wad-crash- dumps Blob container.
Q7. You are developing an ASP.NET MVC application to be used on the Internet. The environment uses Active Directory with delegation to access secure resources.
Users must be able to log on to the application to maintain their personal preferences. You need to use the least amount of development effort to enable users to log on. What should you do?
A. Enable Forms authentication
B. Enable Windows authentication
C. Generate server SSL certificates and install them in IIS
D. Enable Digest authentication
Answer: B
Explanation:
Requirements for Delegation
Delegation relies on Integrated Windows authentication to access resources. There is no limit on the number of computers that you can delegate your account -- you must correctly configure each of them. The Integrated Windows authentication method works only if the following two conditions exist:
/ You set up your network to use the Kerberos authentication protocol that requires Active Directory.
/ You set up the computers and accounts on your network as trusted for delegation. References: https://support.microsoft.com/en-us/kb/810572
Q8. You are developing an ASP.NET MVC application by using Visual Studio 2012. 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. From the Debug menu in Visual Studio 2012, select Exceptions. Enable the Thrown check box for Common Language Runtime Exceptions.
B. From the Debug menu in Visual Studio 2012, 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. Add the following code to the web.config file of the application.<customErrors mode="On" ><error statusCode="404" redirect="CustomErrors.html" /></customErrors>
Answer: A
Explanation:
Configuring the debugger to break for first chance exceptions
To change when the debugger breaks, go to Debug->Exceptionsu2026
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 donu2021t want to enable all First Chance Exceptions, you can find the specific exception types that you wish to configure by using the search box.

Q9. You need to ensure that all customers can delete videos regardless of their browser capability.
Which code segment should you use as the body of the SendAsync method in the DeleteHandler class?

Answer: B
Q10. You need to extend the edit functionality of RunLogController. Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
Q11. You need to configure session storage in the web.config file to meet the technical requirements for scalability.
Which SessionState mode should you use? (Each correct answer presents a complete solution. Choose all that apply.)
A. StateServer
B. InProc
C. AutoDetect
D. SqlServer
Answer: A,D
Explanation:
ASP.NET session state supports several different storage options for session data. Each option is identified by a value in the SessionStateMode enumeration. The following list
describes the available session state modes:
* StateServer mode, which stores session state in a separate process called the ASP.NET state service. This ensures that session state is preserved if the Web application is restarted and also makes session state available to multiple Web servers in a Web farm.
* SQLServer mode stores session state in a SQL Server database. This ensures that session state is preserved if the Web application is restarted and also makes session state available to multiple Web servers in a Web farm.
* InProc mode, which stores session state in memory on the Web server. This is the default.
* Custom mode, which enables you to specify a custom storage provider.
* Off mode, which disables session state.

Q12. When users attempt to retrieve a product from the product page, a run-time exception occurs if the product does not exist.
You need to route the exception to the CustomException.aspx page. Which method should you add to MvcApplication?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: B
Q13. You are preparing for the deployment of an ASP.NET MVC application. You need to generate a deployment manifest.
Which command-line tool should you use?
A. Mage.exe
B. Ngen.exe
C. ALexe
D. Resgen.exe
Answer: A
Explanation:
The Manifest Generation and Editing Tool (Mage.exe) is a command-line tool that supports the creation and editing of application and deployment manifests.
Incorrect:
Not B: The Native Image Generator (Ngen.exe) is a tool that improves the performance of managed applications. Ngen.exe creates native images
Not C: Al.exe generates a file with an assembly manifest, not an deployment manifest, from one or more files that are either resource files or Microsoft intermediate language (MSIL) files.
Not D: Resgen.exe, the Resource File Generator, converts text (.txt or .restext) files and XML-based resource format (.resx) files to common language runtime binary (.resources) files that can be embedded in a runtime binary executable or compiled into satellite assemblies.

Q14. You are developing an ASP.NET MVC application. The application is deployed in a web farm and is accessed by many users.
The application must handle web server failures gracefully. The servers in the farm must share the state information.
You need to persist the application state during the session. What should you implement?
A. A state server
B. Cookieless sessions
C. A web garden on the web servers
D. An InProc session
Answer: A
Explanation:
ASP.NET session state service provides a somewhat slower service than the in-process variant as we need to make calls to a remote server. All session data is stored in memory so shutting down the state machine will wipe out all session data as well.
Incorrect:
Not D: The InProc option is particularly dangerous in a web farm environment. For example imagine one farm machine which stores the session state but not the other. Subsequent web requests from the same user may not read the correct session state.
