You develop an ASP.NET MVC application. The application includes a feature that allows users to reset their passwords. The feature is enabled by a ForgotPassword controller method and a corresponding Razor view.
You need to prevent Cross-Site Request Forgery (CSRF) attacks.
How should you complete the relevant code? To answer, select the appropriate code segment from each list in the answer area.

Answer:

Explanation: Target1: [ValidateAntiForgeryToken] Target2: @Html.AntoForgeryToken() Example:
* At the top of the action that we created to handle the posted form, the one with the [HttpPost] attribute added, we'll add another attribute named [ValidateAntiForgeryToken]. This makes the start of our action now look like the following:
[HttpPost] [ValidateAntiForgeryToken]
public ActionResult ChangeEmail(ChangeEmailModel model)
{
string username = WebSecurity.CurrentUserName;
*rest of function omitted*
* we must add the unique token to the form to change the user's email when we display it. Update the form in the ChangeEmail.aspx view under /Account/ChangeForm:
<% using(Html.BeginForm()) { %>
<%: Html.AntiForgeryToken() %>
<%: Html.TextBoxFor(t=>t.NewEmail) %>
<input type="submit" value="Change Email" />
<% } %>

NEW QUESTION 7
You manage an application that has a custom API. Your company purchases another company. Employees from the purchased company use their own Microsoft Azure Active Directory (Azure AD).
You need to reconfigure the application to ensure that all users can access the application by using the API. You have the following requirements:
Implement authentication for Azure API management.
Configure the API gateway for proper authorization.
Integrate metrics into one dashboard.
Apply additional restrictions to all roles.
What should you implement? To answer, configure the appropriate options in the dialog box in the answer area.
NOTE: Each correct selection is worth one point.

Answer:

Explanation: Box 1: Groups
Add an external Azure AD group
After you enable access for users in an Azure AD instance, you can add Azure AD groups in API Management. Then, you can more easily manage the association of the developers in the group with the desired products.
To configure an external Azure AD group, you must first configure the Azure AD instance on the Identities tab by following the procedure in the previous section.
You add external Azure AD groups from the Groups tab of your API Management instance. Box 2: Policies
Policies are applied inside the gateway which sits between the API consumer and the managed API. The gateway receives all requests and usually forwards them unaltered to the underlying API. However a policy can apply changes to both the inbound request and outbound response.
Box 3: Application Insights
Application Insights is an extensible Application Performance Management (APM) service for web developers on multiple platforms. Use it to monitor your live web application.
Box 4: Role-Based Access Control (RBAC) Apply additional restrictions to all roles.
Azure API Management relies on Azure Role-Based Access Control (RBAC) to enable fine-grained access management for API Management services and entities (for example, APIs and policies).

NEW QUESTION 8
The date of the run must be displayed in ViewsRunlogGetLog.cshtml. The timestamp must not be displayed.
You need to display the date of the run according to the business requirements. Which code segment should you use?

• A. @Html.DisplayFor(model => log.ShortDate)
• B. @log.RunDate.ToString()
• C. @log.RunDate.ToShortDateString()
• D. @Html.DisplayFor(model => log.RunDate)

Answer: A

Explanation: The log file has the ShortDate function which is defined as: Return RunDate.ToLocalTime().ToShortDateString();
This meets the requirement. Note:
Scenario:
* The application uses the ModelsLogModel.cs model.
* The Html.DisplayFor method is typically used to display values from the object that is exposed by the Model property.
The DisplayExtensions.DisplayFor<TModel, TValue> method (HtmlHelper<TModel>, Expression<Func<TModel, TValue>>)
Returns HTML markup for each property in the object that is represented by the Expression expression.
Incorrect:
Not D: The RunDate attribute is defined as DateTime, but the timestamp (the time of day), should not be displayed.

NEW QUESTION 9
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

NEW QUESTION 13
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.

NEW QUESTION 17
You are developing an ASP.NET MVC application.
You need to choose the appropriate Visual Studio templates to use for each test goal.
Which Visual Studio Unit Test project templates should you use? To answer, drag the appropriate Unit Test project template to the correct test goal or test goals. Each project template 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: Box 1: Coded UI Test Project
Automated tests that drive your application through its user interface (UI) are known as coded UI tests (CUITs). These tests include functional testing of the UI controls. They let you verify that the whole application, including its user interface, is functioning correctly. Coded UI Tests are particularly useful where there is validation or other logic in the user interface, for example in a web page. They are also frequently used to automate an existing manual test.
Box 2: Unit Test Project
Unit testing is a software testing method by which individual units of source code, sets of one or more computer program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use.[1] Intuitively, one can view a unit as the smallest testable part of an application.
Box 3: Web Performance and Load Test Project Box 4: Web Performance and Load Test Project
A load test is a container of Web performance tests and unit tests.
A load test exposes many run-time properties that can be modified to generate the desired load simulation. References: https://msdn.microsoft.com/en-us/library/dd286726.aspx
