For better user experience, AJAX can be employed in Razor forms to submit the form without a full _________ of the page.
- Refresh
- Reload
- Redraw
- Postback
AJAX (Asynchronous JavaScript and XML) can be employed in Razor forms to submit the form without a full Postback of the page. This technique allows you to send and receive data from the server without refreshing or reloading the entire web page, resulting in a smoother and more responsive user experience.
You're just starting with ASP.NET Core and Entity Framework. You've created your entity classes, but now you need a way to interact with the database. Which class should you create to manage this?
- DbContext
- DbSet
- SqlConnection
- EntityConnection
In Entity Framework Core, the DbContext class is responsible for managing database connections, tracking changes, and serving as the main entry point for interacting with the database. It provides a bridge between your entity classes and the underlying database, allowing you to perform operations like querying, inserting, updating, and deleting data.
For containerized ASP.NET Core applications aiming for microservice architectures, which tool integration in Visual Studio provides tools for building, running, and orchestrating Docker containers?
- Docker Hub
- Kubernetes
- Azure Kubernetes Service
- Docker Tools
Docker Tools in Visual Studio provide a comprehensive set of features for containerized ASP.NET Core applications. It allows developers to build, run, and orchestrate Docker containers right from within Visual Studio, making it a powerful tool for microservices development.
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.
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.
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.
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.
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.
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.
