While exploring a sample ASP.NET Core MVC project, you see a folder named "Controllers." What is the primary responsibility of files within this folder?
- Displaying web pages to users
- Handling user authentication
- Implementing the application's business logic
- Receiving and processing HTTP requests
The "Controllers" folder in an ASP.NET Core MVC project contains files responsible for receiving and processing HTTP requests. Controllers define action methods that handle incoming requests, make decisions, and interact with models and views to generate responses.
When designing attribute routes, which approach helps in preventing route conflicts?
- Use of route parameters
- Use of a unique route name
- Use of multiple route attributes
- Use of query string parameters
Preventing route conflicts in attribute routing is achieved by providing a unique name to each route using the "name" parameter in the [Route] attribute. This ensures that routes are distinct and won't conflict with each other.
When you want to send a JSON response from your controller, which action result type should you utilize?

Which tool among the following is primarily a command-line tool for .NET operations?
- Visual Studio
- .NET CLI
- JetBrains Rider
- Eclipse
.NET CLI (Command-Line Interface) is a command-line tool primarily used for .NET operations. It allows developers to perform tasks like building, testing, and publishing .NET applications directly from the command line, making it a versatile tool for developers who prefer command-line interfaces.
What purpose does the .NET Core CLI serve in ASP.NET Core development?
- It's used for ordering food online
- It helps in managing NuGet packages
- It provides a command-line interface for creating, building, and managing ASP.NET Core projects
- It's a design pattern in software development
The .NET Core CLI (Command-Line Interface) plays a crucial role in ASP.NET Core development. It allows developers to interact with their projects through the command line, facilitating tasks like project creation, building, testing, and running. It's a powerful tool for automating development tasks and managing ASP.NET Core projects efficiently.
Which of the following is a containerization tool that can be used with ASP.NET Core for deployment?
- Docker
- Jenkins
- Kubernetes
- Git
Docker is a popular containerization tool that can be used with ASP.NET Core for deployment. Docker containers encapsulate the application and its dependencies, making it easy to deploy and run consistently across different environments.
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.
What is the primary function of the dotnet command when used without any additional arguments in the CLI?
- It compiles the current project and produces an executable binary.
- It installs the latest version of the .NET SDK.
- It displays the help menu for the dotnet CLI.
- It updates all NuGet packages in the current project.
When the dotnet command is used without any additional arguments, it displays the help menu for the .NET CLI. This menu provides a list of available commands and options, helping developers navigate and use the CLI effectively. It's a handy way to explore the CLI's capabilities and understand how to use various commands and options.
