How can you restrict an action method to respond only to HTTP POST requests in ASP.NET Core MVC?
- By using the [HttpPost] attribute
- By defining a custom route
- By setting the action method as private
- By using a middleware
To restrict an action method to respond only to HTTP POST requests in ASP.NET Core MVC, you can decorate the method with the [HttpPost] attribute. This attribute ensures that the method can only be invoked when an HTTP POST request is made to its associated URL.
If an action within a controller with [Authorize] should be accessible without authorization, you can use the [_________] attribute.
- [AllowAnonymous]
- [Unsecured]
- [IgnoreAuthorization]
- [PublicAccess]
If an action within a controller with [Authorize] should be accessible without authorization, you can use the [AllowAnonymous] attribute. This attribute allows you to exempt specific actions from the global authorization policy, making them accessible to all users, even if other parts of the controller require authorization.
If you need to create a real-time communication application, the ________ template of ASP.NET Core is designed for this purpose.
- Real-Time
- WebSockets
- SignalR
- Messaging
The "SignalR" template in ASP.NET Core is specifically designed for creating real-time communication applications. SignalR allows bi-directional communication between the server and clients, making it ideal for applications like chat, online gaming, and live notifications.
What is the primary purpose of a Web API in ASP.NET Core?
- Serve as a user authentication system
- Facilitate communication between web applications
- Manage database schema
- Render web pages
A Web API in ASP.NET Core primarily serves to facilitate communication between web applications. It enables applications to exchange data and functionality over HTTP, making it a crucial component for building RESTful services or supporting AJAX requests in web applications. It does not typically handle user authentication or manage database schemas directly.
In a team development scenario, two developers have created separate migrations for different features at the same time. Before merging these changes into the main branch, what precautions or steps should be taken regarding the Identity migrations?
- Delete one developer's migrations to avoid conflicts
- Ensure both developers use the same database provider
- Collaborate to combine the migrations and resolve conflicts
- Let Entity Framework Core handle the merge automatically
When multiple developers work on separate migrations, it's essential to collaborate and combine the migrations before merging into the main branch. This prevents conflicts and ensures a consistent database schema. Entity Framework Core doesn't handle automatic merge of migrations, so developers need to coordinate their efforts to avoid issues.
In an e-commerce application, after a user successfully checks out, you want to redirect them to a confirmation page. Which action result can achieve this redirection?
- Redirect
- Ok
- View
- BadRequest
To achieve a redirection after a successful action, you should use the Redirect action result. It allows you to specify the URL to which the user should be redirected, typically a confirmation page in this case. The Redirect result returns an HTTP 302 status code, indicating a temporary redirect.
If you want to enforce that passwords must contain a non-alphanumeric character in ASP.NET Core Identity, which property should you set?
- RequireNonAlphanumeric
- RequireUppercase
- RequireDigit
- RequireLowercase
In ASP.NET Core Identity, the RequireNonAlphanumeric property should be set to true if you want to enforce that passwords must contain at least one non-alphanumeric character (e.g., special symbol). This adds an extra layer of security to user passwords.
The session information in ASP.NET Core is stored using _________ by default.
- Cookies
- Local Storage
- Session Storage
- Database
In ASP.NET Core, session information is typically stored using cookies by default. Cookies are small pieces of data sent from a web server and stored on the client's browser. They are commonly used to maintain user state and session data across HTTP requests, making them suitable for storing session information.
Dependency injection in ASP.NET Core MVC allows services to be injected into controllers via their _________.
- Constructors
- Properties
- Methods
- Fields
Dependency injection in ASP.NET Core MVC allows services to be injected into controllers via their constructors. This approach promotes the use of constructor injection for better testability and maintainability of your controllers, ensuring that required services are provided when the controller is created.
In scenarios with table splitting in Entity Framework Core, how is it ensured that multiple entities map to a single table?
- Using the .ToTable() method with the same table name
- Manually specifying the same columns for multiple entities
- Table splitting doesn't allow multiple entities in one table
- By using the .MapToStoredProcedures() method
To ensure that multiple entities map to a single table in table splitting scenarios, you can use the .ToTable() method with the same table name for both entities. This tells Entity Framework Core to store both entities in the same table in the database.
