You're tasked with displaying a list of products on a webpage using ASP.NET Core. Which type of Razor view would be most appropriate for this task?
- Index.cshtml
- Layout.cshtml
- Partial.cshtml
- Model.cshtml
In ASP.NET Core, the appropriate Razor view for displaying a list of products would typically be "Index.cshtml." This view is commonly used for rendering the main content of a webpage and displaying data.
The primary method used in a Razor Layout to render content from a child view is _______.
- @RenderBody()
- @RenderSection()
- @RenderPage()
- @RenderPartial()
The primary method used in a Razor Layout to render content from a child view is "@RenderBody()". This directive is used to render the main content of the child view within the layout.
In what scenario might you use the _ViewImports.cshtml file in conjunction with Razor Layout Views?
- To specify common namespaces and directives
- To define layout-specific CSS styles
- To create global variables for all views
- To include JavaScript libraries
The _ViewImports.cshtml file is used in ASP.NET Core Razor Views to specify common namespaces and directives that should be available across multiple views. This is particularly useful for avoiding redundancy and ensuring consistency in your views. The other options are not the primary purpose of the _ViewImports.cshtml file.
In a scenario where you want to cache an action result for a specified duration, which attribute or method can be combined with an action result to achieve this behavior?
- [ResponseCache] attribute
- [OutputCache] attribute
- CacheResult() method
- [Cache] attribute
To cache an action result for a specified duration in ASP.NET Core, you can use the [ResponseCache] attribute. This attribute allows you to specify caching options like cache duration, location, and more at the action method level. By applying this attribute to your action method, you can control caching behavior and improve performance by serving cached responses when appropriate.
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.
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.
When creating a custom Tag Helper, which class should it derive from?
- TagHelper
- Controller

In which type of testing do you test individual components or units of software in isolation?
- Integration Testing
- System Testing
