In one of the tutorials, the controller sends back data in a format that JavaScript can easily parse. What type of action result does this refer to?

  • ViewResult
  • JsonResult
  • RedirectToActionResult
  • ContentResult
When a controller sends data that JavaScript can easily parse, it usually returns a JsonResult. This action result serializes data into JSON format, making it suitable for consumption by JavaScript code.

The property that determines the maximum time span a user can remain locked out after failed attempts is called _________.

  • Lockout Timeout
  • Password Expiry
  • Two-Factor Authentication
  • Lockout Duration
The "Lockout Duration" property in ASP.NET Core Identity determines the maximum time span a user can remain locked out after a specified number of failed login attempts. This feature enhances security by temporarily locking out accounts after too many unsuccessful login attempts.

You've written a service in your ASP.NET Core application that interacts with an external API. To test this service without making actual API calls, what testing approach might you adopt?

  • Mocking
  • Load Testing
  • Integration Testing
  • Regression Testing
To test a service without making actual API calls, you would typically adopt the approach of "mocking." Mocking involves creating simulated objects (mocks) that mimic the behavior of real objects, allowing you to isolate and test the service's logic without involving external dependencies.

SignalR in ASP.NET Core is used to establish which type of communication?

  • One-way communication
  • Synchronous communication
  • Real-time, bidirectional communication
  • Offline communication
SignalR in ASP.NET Core is used to establish real-time, bidirectional communication between the server and connected clients. It's especially useful for building applications that require instant updates and interactions, such as chat applications, live notifications, or online gaming. It doesn't handle one-way, synchronous, or offline communication.

In scenarios with high-security requirements, which ASP.NET Core Identity feature would be best to enforce to require users to change their passwords periodically?

  • Password Expiration Policy
  • Two-Factor Authentication
  • Role-Based Authorization
  • Identity Server
To enforce users to change their passwords periodically in ASP.NET Core Identity, you can configure a password expiration policy. This ensures that users must reset their passwords after a defined period, enhancing security for sensitive applications.

When setting up a Continuous Integration (CI) pipeline for an ASP.NET Core application, why might you decide to include both unit tests and integration tests?

  • To ensure that all code changes do not introduce regressions and maintain existing functionality.
  • To make the CI pipeline more time-efficient.
  • To avoid conflicts between team members' code.
  • To focus solely on unit tests as integration tests are not suited for CI.
Including both unit tests and integration tests in a CI pipeline for ASP.NET Core is essential to ensure that code changes do not introduce regressions or break existing functionality. Unit tests validate the correctness of individual components, while integration tests verify that these components work correctly when combined. This helps maintain the application's overall quality and reliability.

In what scenario would you need to manually set the name attribute of an input field in a Razor form, despite using model binding?

  • When using complex model hierarchies
  • When applying client-side validation
  • When using tag helpers
  • When handling file uploads
You may need to manually set the name attribute of an input field in a Razor form when dealing with complex model hierarchies. Model binding can sometimes generate complex names that may not match your desired structure, so manually setting the name attribute ensures proper binding in such cases.

You're tasked with creating a middleware that logs every incoming request's User-Agent header. Which approach would you take to capture this data in ASP.NET Core?

  • Using UseMiddleware extension method
  • Implementing a custom middleware class
  • Utilizing a filter attribute
  • Directly modifying the ASP.NET Core pipeline
To capture the User-Agent header in ASP.NET Core, you would create a custom middleware class that intercepts incoming requests. This middleware class can access the request headers and log the User-Agent information as needed. The UseMiddleware extension method is used to add custom middleware components to the pipeline.

How can you set a default document (like index.html) to be served when the user accesses the root URL in an ASP.NET Core app?

  • Use the app.UseDefaultDocument() method
  • Configure the DefaultDocument property in Startup.cs
  • Add a default.html file to the project
  • Use the app.UseIndexFile() method
To set a default document like index.html to be served when the user accesses the root URL in an ASP.NET Core app, you can configure the DefaultDocument property in Startup.cs. This allows you to specify the default file that should be served when a directory is requested without a specific file name.

You're tasked with creating a layout that has an optional sidebar. Only specific views will provide content for this sidebar, while others won't. How would you design this in the Razor layout?

  • Use sections in the Razor layout to define the sidebar content, and individual views can choose to fill the sidebar section or leave it empty.
  • Create separate layouts for views with and without a sidebar.
  • Use JavaScript to conditionally load the sidebar content in the client-side code.
  • Use a global variable to toggle the sidebar's visibility in all views.
To create a layout with an optional sidebar in ASP.NET Core using Razor, you can use sections in the layout to define the sidebar content. Individual views can then choose to fill the sidebar section or leave it empty, allowing for flexibility in displaying the sidebar based on specific view requirements.
