NEW QUESTION 15
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: AD

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.

You are developing an ASP.NET MVC application. You plan to use OAuth to authenticate users to the application.
You need to use the correct authentication data in the application.
What should you do? To answer, drag the appropriate data element to the correct location or locations. Each data element may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

Answer:

Explanation: Live Connect implements the OAuth 2.0 protocol to authenticate users.
In the authorization code grant flow, the client makes authorization requests by using request_type=code. The following diagram illustrates how the authorization code grant flow works.

1. The client starts the flow by directing the resource owner's user agent to the Live Connect authorization endpoint, by using a URL in the following format.
https://login.live.com/oauth20_authorize.srf?client_id=CLIENT_ID&scope=SCOPES&response_type=code&re
2. The authorization server authenticates the resource owner via the user agent, and establishes whether the resource owner grants or denies the client's access request.
3. Assuming that the resource owner has granted access, the Live Connect authorization server redirects the user agent to the client by using the redirection URI that was provided in the initial request.
4. The user agent calls the client with the redirection URI, which includes an authorization code and any local state that was provided by the client. For example: http://contoso.com/Callback.htm?code=AUTHORIZATION_CODE.
5. The client requests an access token from the authorization server's token endpoint by using its client credentials for authentication, and includes the authorization code that was received in the previous step.
6. If the credentials are valid, the authorization server responds by returning an access token. References: https://msdn.microsoft.com/en-us/library/hh243647.aspx

NEW QUESTION 17

• B. Enable the Thrown check box for Common Language Runtime Exceptions.
• C. From the Debug menu in Visual Studio 2012, select Exception
• D. Disable the User-unhandled check box for Common Language Runtime Exceptions.
• E. Add the following code to the web.config file of the application.<customErrors mode="On" ><error statusCode="500" redirect="CustomErrors.html" /></customErrors>
• F. 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->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.
