You're designing a form in your Razor view and want to leverage built-in tag helpers for form generation. Which directive should you ensure is present at the top of your view to use these tag helpers?
- @addTagHelper
- @model
- @using
- @inject
To use built-in tag helpers for form generation in an ASP.NET Core Razor view, you should ensure the presence of the @addTagHelper directive at the top of your view. This directive specifies which tag helpers should be available in the view and is typically configured in the _ViewImports.cshtml file for global usage.
You're developing a multi-tenant application where each tenant has its own database. Which Entity Framework Core feature can help you manage multiple databases effectively?
- Dynamic Connection Strings
- DbContext Pooling
- Database Sharding
- Lazy Loading
DbContext Pooling in Entity Framework Core allows you to efficiently manage multiple database connections. In a multi-tenant application, you can use DbContext pooling to reuse and efficiently manage connections for each tenant's database, improving performance and resource utilization.
You're developing a web application and need to implement a feature where users can log in using their email or phone number. How can ASP.NET Core Identity support this requirement?
- Custom Authentication Middleware
- Custom Identity Provider
- Built-in Support
- Third-party Authentication Service
ASP.NET Core Identity provides built-in support for various user authentication methods, including email and phone number. Developers can easily configure Identity to enable these features and allow users to log in using either their email or phone number. This simplifies authentication implementation.
When setting up a Continuous Integration (CI) pipeline for an ASP.NET Core application, why might you decide to include both unit tests and integration tests?
- To ensure that all code changes do not introduce regressions and maintain existing functionality.
- To make the CI pipeline more time-efficient.
- To avoid conflicts between team members' code.
- To focus solely on unit tests as integration tests are not suited for CI.
Including both unit tests and integration tests in a CI pipeline for ASP.NET Core is essential to ensure that code changes do not introduce regressions or break existing functionality. Unit tests validate the correctness of individual components, while integration tests verify that these components work correctly when combined. This helps maintain the application's overall quality and reliability.
In scenarios with high-security requirements, which ASP.NET Core Identity feature would be best to enforce to require users to change their passwords periodically?
- Password Expiration Policy
- Two-Factor Authentication
- Role-Based Authorization
- Identity Server
To enforce users to change their passwords periodically in ASP.NET Core Identity, you can configure a password expiration policy. This ensures that users must reset their passwords after a defined period, enhancing security for sensitive applications.
SignalR in ASP.NET Core is used to establish which type of communication?
- One-way communication
- Synchronous communication
- Real-time, bidirectional communication
- Offline communication
SignalR in ASP.NET Core is used to establish real-time, bidirectional communication between the server and connected clients. It's especially useful for building applications that require instant updates and interactions, such as chat applications, live notifications, or online gaming. It doesn't handle one-way, synchronous, or offline communication.
You've written a service in your ASP.NET Core application that interacts with an external API. To test this service without making actual API calls, what testing approach might you adopt?
- Mocking
- Load Testing
- Integration Testing
- Regression Testing
To test a service without making actual API calls, you would typically adopt the approach of "mocking." Mocking involves creating simulated objects (mocks) that mimic the behavior of real objects, allowing you to isolate and test the service's logic without involving external dependencies.
The property that determines the maximum time span a user can remain locked out after failed attempts is called _________.
- Lockout Timeout
- Password Expiry
- Two-Factor Authentication
- Lockout Duration
The "Lockout Duration" property in ASP.NET Core Identity determines the maximum time span a user can remain locked out after a specified number of failed login attempts. This feature enhances security by temporarily locking out accounts after too many unsuccessful login attempts.
In one of the tutorials, the controller sends back data in a format that JavaScript can easily parse. What type of action result does this refer to?
- ViewResult
- JsonResult
- RedirectToActionResult
- ContentResult
When a controller sends data that JavaScript can easily parse, it usually returns a JsonResult. This action result serializes data into JSON format, making it suitable for consumption by JavaScript code.
To define a named section within a Razor view that can be rendered in a specific place in the layout, you use the _______ directive.
- @Section
- @LayoutSection
- @NamedSection
- @RenderSection
To define a named section within a Razor view that can be rendered in a specific place in the layout, you use the "@Section" directive. You can specify a name for the section, and in the layout, you can use "@RenderSection" to render the content of that named section at a designated location.
In an ASP.NET Core application, you've noticed that users are setting easily guessable passwords. To remedy this, which Identity configuration would you tweak to enforce stricter password criteria?
- Security Headers
- Cookie Authentication
- Password Options
- Identity Server
To enforce stricter password criteria, you would tweak the Password Options configuration in ASP.NET Core Identity. This includes setting options like RequiredLength, RequiredUniqueChars, RequireLowercase, RequireUppercase, and RequireDigit to make passwords more complex and less guessable.
While working on an ASP.NET Core application, you realize you need functionalities like Git integration, debugging, and extensions. Which lightweight editor, enriched with plugins, would be ideal for this purpose?
- Visual Studio
- Sublime Text
- Notepad++
- Visual Studio Code
Visual Studio Code is a lightweight code editor that's ideal for ASP.NET Core development. It offers Git integration, debugging support, and a rich ecosystem of extensions that can enhance your development workflow. It's particularly popular among developers for its versatility and extensibility.
