You've been given a design for a registration page that contains fields like username, password, and email. Which tool or feature in ASP.NET Core will help you create a corresponding backend model for this design?
- Entity Framework Core
- Razor Pages
- ASP.NET Core Identity
- ASP.NET Core Middleware
To create a corresponding backend model for the registration page, you can use Entity Framework Core. Entity Framework Core allows you to define data models that represent database tables, making it easier to work with data in your ASP.NET Core application.
During development, you notice that accessing a related entity property causes an additional query to the database. This was not the intended behavior, and you wish to load related data upfront. Which loading strategy should you employ?
- Lazy Loading
- Eager Loading
- Explicit Loading
- No Loading
To load related data upfront and avoid additional queries, you should employ "Eager Loading." Eager Loading allows you to retrieve related entities in a single query by specifying what related data to include using the Include method in Entity Framework Core.
To pass data from a controller to a view, you can use a ________ object.
- ViewData
- ViewBag
- TempData
- Model
To pass data from a controller to a view, you can use a Model object. Models are classes that define the data structure and properties you want to pass to the view. They enable strong typing and are a fundamental part of the Model-View-Controller (MVC) architecture in ASP.NET Core.
To customize authorization logic in ASP.NET Core, one can implement the _________ interface.
- IAuthorizationFilter
- IAuthorizationMiddleware
- IAuthorizationProvider
- ICustomAuthorization
To customize authorization logic in ASP.NET Core, you can implement the IAuthorizationFilter interface. This interface allows you to create custom authorization logic that can be applied to controllers and actions. It gives you fine-grained control over how authorization is performed for specific requests.
The _______ method is used to add and configure the necessary middleware for routing in ASP.NET Core.
- UseRouting
- AddRouting
- ConfigureRouting
- MapRouting
The correct method is AddRouting. This method is used to add and configure the necessary middleware for routing in ASP.NET Core. It's a fundamental step in setting up routing for your web application.
What keyword is used in the route template to define a variable segment?
- {var}
- [var]
- $var$
- :var
In a route template in ASP.NET Core, you use curly braces {} to define a variable segment. This allows you to capture dynamic parts of a URL, such as IDs or names, and pass them as parameters to the corresponding action method.
For more environment-specific settings in an ASP.NET Core application, one might use files like appsettings.__________.json.
- development
- production
- environment
- config
In ASP.NET Core, environment-specific settings can be stored in JSON configuration files named appsettings.{EnvironmentName}.json. These files allow you to configure settings specific to different environments like development, production, or any custom environment you define.
You're working on an enterprise application where specific endpoints should be accessible only to users from the "HR" and "Admin" departments. How would you enforce this using the [Authorize] attribute?
- Define an authorization policy that checks the user's department and apply it using the [Authorize] attribute.
- Create a custom attribute for HR and Admin access and use it on the controller actions.
- Use role-based authorization and assign roles to users based on their department.
- Use URL-based access control by including department information in the route.
To restrict access to specific departments, you can define an authorization policy that checks the user's department and apply it using the [Authorize] attribute. This allows you to control access at the action level based on the user's department affiliation.
In ASP.NET Core Razor views, what's the role of the AntiForgeryToken?
- To protect against Cross-Site Request Forgery (CSRF) attacks
- To encrypt sensitive form data
- To validate user credentials
- To enhance page load performance
The AntiForgeryToken in ASP.NET Core Razor views is primarily used to protect against Cross-Site Request Forgery (CSRF) attacks. It generates a hidden form field containing a token that is validated on the server when the form is submitted. This ensures that the form submission originates from a trusted source, preventing unauthorized actions.
How can you override or bypass the [Authorize] attribute applied at the controller level for a specific action?
- [AllowAnonymous] attribute
- [Authorize(Roles = "Admin")]
- [IgnoreAuthorization] attribute
- [SkipAuthorization] attribute
You can override or bypass the [Authorize] attribute applied at the controller level for a specific action by using the [AllowAnonymous] attribute on that specific action. This attribute allows unauthenticated access to the action, even if the controller has a broader authorization policy.
