When you want to use a namespace across multiple Razor views without adding it to each view, where should you define it?
- In the _ViewStart.cshtml file
- In the _Layout.cshtml file
- In the _ViewImports.cshtml file
- In each individual Razor view
You should define a namespace that you want to use across multiple Razor views in the _ViewImports.cshtml file. This file is specifically designed to consolidate 'using' directives, making them accessible throughout the views that share it, thereby improving code organization and reusability.
In ASP.NET MVC, Master Pages have been replaced with _______ in Razor views.
- Partial Views
- Layout Pages
- Helper Pages

In ASP.NET Core Razor views, Master Pages have been replaced with "Layout Pages." Layout Pages define the overall structure and common elements for views, similar to Master Pages in previous versions of ASP.NET. They provide a consistent layout for multiple views within your application.
Which part of the MVC pattern is primarily concerned with how the application's data is represented and manipulated?
- Model
- View
- Controller
- Middleware

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.
Which protocol does SignalR use primarily before falling back to other techniques?
- WebSocket
- HTTP
- FTP
- TCP
SignalR primarily uses the WebSocket protocol for real-time communication due to its low latency and bidirectional capabilities. WebSocket provides a full-duplex communication channel, making it ideal for applications requiring instant updates. SignalR gracefully falls back to other techniques like HTTP long polling or Server-Sent Events for compatibility with older browsers or network restrictions.
In an ASP.NET Core project, where are the application's dependencies and SDKs defined?
- appsettings.json
- Startup.cs
- project.json
- .csproj files
In an ASP.NET Core project, application dependencies and SDK versions are typically defined in the .csproj files. These files specify the packages, libraries, and tools required for the project. The .csproj files play a crucial role in managing the project's dependencies and ensuring the correct versions are used.
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.
