Which part of the MVC pattern is primarily concerned with how the application's data is represented and manipulated?
- Model
- View
- Controller
- Middleware
In the MVC pattern, the Model is primarily concerned with how the application's data is represented and manipulated. It encapsulates the business logic, data storage, and interactions with the database. It acts as a bridge between the Controller and the View, providing the necessary data to be displayed.
After completing the development of a feature, you decide to run tests to ensure that your new code doesn't break existing functionality. What is this type of testing called?
- Regression Testing
- Performance Testing
- Usability Testing
- Smoke Testing
Running tests after developing a new feature to ensure that existing functionality remains unaffected is known as Regression Testing. It helps catch unintended side effects or bugs introduced by new code changes.
You've been asked to modify the configurations that get loaded during the startup of your ASP.NET Core application. Which file should you primarily focus on?
- Startup.cs
- appsettings.json
- Program.cs
- HomeController.cs
In an ASP.NET Core application, the Startup.cs file is where you primarily configure the application's services, middleware pipeline, and other startup-related settings. This is where you can modify how the application behaves during startup.
In a certain scenario, you want to display a list of items in multiple views without repeating the same HTML and C# code. What would be the best approach in Razor views?
- Razor Sections
- Razor Partials
- Razor Components
- Razor Views
Razor Partials are reusable components in Razor views. They allow you to define a piece of HTML and C# code once and then include it in multiple views. This approach ensures code reusability and reduces duplication.
In which order does ASP.NET Core execute middleware components?
- Sequentially in the order they are added
- Random order
- Alphabetical order
- In parallel
ASP.NET Core executes middleware components sequentially in the order they are added to the application's request pipeline. This order is significant because it determines the sequence of processing for incoming requests and outgoing responses as they pass through each middleware component.
You've just started working on an ASP.NET Core project that uses Identity for user management. What are migrations primarily used for in this context?
- Managing the database schema
- Managing user authentication
- Managing user roles
- Managing user sessions
In an ASP.NET Core project with Identity, migrations are primarily used for managing the database schema. They allow you to create, update, and version your database schema as your application evolves. This is crucial for user management as it involves the creation and maintenance of user-related tables.
SignalR is known for enabling ________ communication, which allows the server to push content to connected clients.
- Real-time
- Batch
- Asynchronous
- Synchronous
SignalR is a library in ASP.NET Core known for enabling real-time communication. It allows the server to push content to connected clients in real-time, making it ideal for applications that require instant updates, such as chat apps and live dashboards.
When combining multiple [Authorize] attributes on a single action or controller, how does ASP.NET Core evaluate the requirements?
- Logical AND
- Logical OR
- Randomly
- Sequentially
ASP.NET Core evaluates the requirements of multiple [Authorize] attributes logically using AND. This means all authorization requirements specified in these attributes must be met for a user to access the action or controller.
You're new to ASP.NET Core and are confused about where to specify the common design elements (like headers and footers) that appear on every page. Which Razor concept should you explore for this purpose?
- ViewComponents
- Razor Layouts
- Partial Views
- Tag Helpers
To specify common design elements like headers and footers that appear on every page, you should explore Razor Layouts. Razor Layouts allow you to define a shared layout for your views, enabling you to encapsulate these common elements.
How can you define a route in ASP.NET Core to be available only for specific HTTP methods using attribute routing?
- [HttpPut], [HttpPost]
- [HttpGet], [HttpPost]
- [HttpDelete], [HttpGet]
- [HttpPatch], [HttpPut]
In ASP.NET Core, you can specify the HTTP methods a route should be available for using attributes like [HttpGet] or [HttpPost] above the controller action method. For example, [HttpGet] ensures the route is available for HTTP GET requests, and [HttpPost] for HTTP POST requests.
