For cross-platform development in ASP.NET Core, what runtime should be targeted to ensure the application can run on different OS types?
- .NET Framework
- .NET Core
- .NET Standard
- .NET Runtime
To achieve cross-platform compatibility in ASP.NET Core, developers should target the .NET Core runtime. .NET Core is designed to be cross-platform and supports running applications on various operating systems, making it the preferred choice for cross-platform development.
To facilitate user registration in ASP.NET Core, the Identity framework offers a predefined _________ that contains methods for creating, deleting, and managing users.
- UserManager
- RoleManager
- AppDbContext
- Authentication
The Identity framework in ASP.NET Core provides the UserManager class, which contains methods for managing user accounts, including creating, deleting, and updating user information. It is a fundamental component for user registration and management in ASP.NET Core applications.
You're developing a web application and need to implement a feature where users can log in using their email or phone number. How can ASP.NET Core Identity support this requirement?
- Custom Authentication Middleware
- Custom Identity Provider
- Built-in Support
- Third-party Authentication Service
ASP.NET Core Identity provides built-in support for various user authentication methods, including email and phone number. Developers can easily configure Identity to enable these features and allow users to log in using either their email or phone number. This simplifies authentication implementation.
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 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.
To define a named section within a Razor view that can be rendered in a specific place in the layout, you use the _______ directive.
- @Section
- @LayoutSection
- @NamedSection
- @RenderSection
To define a named section within a Razor view that can be rendered in a specific place in the layout, you use the "@Section" directive. You can specify a name for the section, and in the layout, you can use "@RenderSection" to render the content of that named section at a designated location.
