Which method in the Startup class is commonly used to configure middleware?

  • Configure
  • ConfigureServices
  • UseMiddleware
  • ConfigureMiddleware
The Configure method in the Startup class is commonly used to configure middleware in ASP.NET Core. Inside this method, you can specify the order in which middleware components are added to the pipeline and define how they process requests and responses.

The process of mapping an incoming request to a route template is known as _______.

  • Routing
  • Mapping
  • Dispatching
  • URL Resolution
The correct term is "Dispatching." Dispatching refers to the process of mapping an incoming HTTP request to a specific route template in your ASP.NET Core application. It's a crucial step in determining which controller and action should handle the request.

You're tasked with building a new feature in an ASP.NET Core application where each user profile should be accessible via a URL like /users/{username}. How can attribute routing facilitate this?

  • Use [Route("users/{username}")] on the action method
  • Modify the appsettings.json file
  • Create a new middleware component
  • Add a user-profile route in Startup.cs
In ASP.NET Core, attribute routing allows you to define custom routes for your controllers and action methods. By using the [Route] attribute with the desired route template, you can specify that the user profile should be accessible via /users/{username}.

For a high-availability deployment of an ASP.NET Core application, which strategy involves deploying the application in such a way that there are multiple instances running simultaneously, typically in different geographical regions?

  • Failover Clustering
  • Load Balancing
  • Georeplication
  • Active-Passive Deployment
Georeplication is a strategy that ensures high availability by deploying application instances in different geographical regions. This approach minimizes downtime in case of regional outages or disasters, providing a robust and fault-tolerant architecture.

Which type of testing focuses on testing multiple components of an application together?

  • Unit Testing
  • Component Testing
  • Integration Testing
  • Regression Testing
Integration testing concentrates on testing multiple components of an application together. It ensures that these components work correctly when combined and can communicate effectively. It's an essential step between unit testing and system testing in the testing life cycle.

If you have a URL like /products/5, what would be a suitable route template to capture the product's id?

  • /products/{id:int}
  • /products/{id}
  • /products/{product_id}
  • /products?id=5
To capture the product's id from a URL like /products/5, you can use the route template /products/{id}. The {id} segment is a placeholder for the product's id, and the :int constraint ensures that it must be an integer value. This allows you to retrieve and process the id as a parameter in your controller action.

You are building a RESTful API using ASP.NET Core. In a scenario where the resource is not found, which action result should you use to represent this state?

  • NotFound
  • BadRequest
  • Ok
  • InternalServerError
In ASP.NET Core, the NotFound action result is used to represent a situation where the requested resource is not found. It returns an HTTP 404 status code, indicating that the resource could not be located. This is the appropriate response for this scenario.

Which method allows you to update identity-related configurations at runtime rather than during startup?

  • IOptionsSnapshot
  • IConfiguration
  • IOptionsMonitor
  • IOptions
To update identity-related configurations at runtime, you should use IOptionsMonitor. This allows for dynamic configuration changes without requiring a server restart, making it suitable for scenarios where runtime updates are essential.

What is the purpose of the asp-for attribute in a Razor form input field?

  • It specifies the input field's ID.
  • It associates the input field with a model property.
  • It sets the input field's value.
  • It defines the input field's validation rules.
The purpose of the asp-for attribute in a Razor form input field is to associate the input field with a model property. It creates a binding between the input field and the model property, allowing automatic data binding when the form is submitted. This attribute is essential for model binding in ASP.NET Core, ensuring that form data is correctly mapped to model properties.

In a team discussion, someone suggests using ASP.NET Core Identity. What is a common reason for integrating this into a web application?

  • Centralized User Management
  • Color Scheme Customization
  • Serverless Architecture
  • Advanced Data Analytics
A common reason for integrating ASP.NET Core Identity into a web application is centralized user management. It allows the application to have a unified system for managing user accounts, roles, and permissions. This simplifies user authentication, authorization, and user data management, making it easier for teams to maintain and secure the application.
