How does ASP.NET Core Identity store user data by default?
- In a SQL Server database
- In a NoSQL database
- In plain text files
- In memory
ASP.NET Core Identity, by default, stores user data in a SQL Server database. This includes user profiles, passwords (hashed and salted), and other related data in a structured manner for security and scalability.
Consider a scenario where you need to return a partial view from your controller. Which action result should you use?
- ViewResult
- PartialViewResult
- ContentResult
- JsonResult
When you want to return a partial view from a controller action, you should use PartialViewResult. This action result is specifically designed to render partial views, allowing you to return a portion of the HTML content to be inserted into a larger view.
ASP.NET Core supports the dependency injection design pattern. The __________ method in the Startup.cs file is used to configure services for this purpose.
- ConfigureServices
- Configure
- AddServices
- RegisterServices
In ASP.NET Core, the ConfigureServices method in the Startup.cs file is used to configure services, including registering dependencies for dependency injection. This method allows you to configure how various parts of your application should interact and obtain the services they need.
In an e-commerce application, you have a controller that manages orders, and it is protected using the [Authorize] attribute. However, you wish to allow a public tracking feature where users can see the status of their order without logging in. How would you implement this?
- Create a separate controller or action without the [Authorize] attribute for public order tracking.
- Use client-side authentication to allow access to order tracking.
- Use a cookie-based authentication mechanism for order tracking.
- Allow anonymous access to the entire order controller.
To implement a public order tracking feature, you should create a separate controller or action without the [Authorize] attribute. This allows unauthenticated users to access order tracking while keeping the rest of the order management secure with authentication.
In ASP.NET Core, if you want to serve static files like images, CSS, and JavaScript, you need to add the _________ middleware.
- StaticFile
- FileServer
- ContentDelivery
- StaticContent
To serve static files like images, CSS, and JavaScript in ASP.NET Core, you need to add the StaticFile middleware. This middleware enables your application to serve these files efficiently without needing to write custom code for each file request. It's essential for building web applications with static assets.
You want to use a database with your ASP.NET Core web application. Which ORM (Object-Relational Mapping) framework is natively supported by ASP.NET Core for this purpose?
- Entity Framework Core
- Hibernate
- SQLAlchemy
- Doctrine
Entity Framework Core (EF Core) is the ORM framework natively supported by ASP.NET Core. It simplifies database access by allowing developers to work with databases using C# objects, making it a popular choice for database interaction in ASP.NET Core applications.
What is the role of the "wwwroot" directory in an ASP.NET Core project?
- It contains configuration files for the project.
- It stores static web assets such as HTML, CSS, and JavaScript files accessible to the client-side of the application.
- It houses database connection strings.
- It stores server-side code files.
The "wwwroot" directory in an ASP.NET Core project serves as the location for static web assets that can be directly accessed by clients. These assets include HTML, CSS, JavaScript files, images, and other client-side resources. Placing them here ensures that they are publicly available without needing special routing or controller actions.
What is the difference between authentication and authorization in the context of the [Authorize] attribute?
- Authentication verifies the user's identity, while authorization controls what actions they are allowed to perform.
- Authentication and authorization are the same things.
- Authentication deals with user roles, while authorization verifies the user's identity.
- Authorization only checks if the user is logged in.
In the context of the [Authorize] attribute, authentication is the process of verifying the user's identity (usually through login) and determining who they are. Authorization, on the other hand, decides what actions or resources the authenticated user is allowed to access.
You've heard about two-factor authentication for enhancing security. How can ASP.NET Core Identity help in implementing this feature?
- Built-in Support for Two-Factor Authentication
- Seamless Integration with Third-Party APIs
- Automatic Firewall Configuration
- Enhanced Database Encryption
ASP.NET Core Identity simplifies the implementation of two-factor authentication by offering built-in support. This means that developers can easily enable and configure two-factor authentication for user accounts within their applications, adding an extra layer of security through methods like SMS codes or authenticator apps.
In an online quiz application, you want to ensure that only teachers can create or edit questions. Which attribute in ASP.NET Core will help you achieve this functionality?
- [AllowAnonymous]
- [Authorize]
- [Authorize(Roles = "Student")]
- [Authorize(Roles = "Teacher")]
To restrict the creation or editing of questions to teachers only, you would use the [Authorize(Roles = "Teacher")] attribute. This ensures that only users with the "Teacher" role can access the specified resources. [AllowAnonymous] would allow everyone, [Authorize] is a generic authorization attribute, [Authorize(Roles = "Student")] restricts to students only, which is the opposite of the desired behavior.
