In your ASP.NET Core application, you notice that some middleware is not executing as expected. Considering the middleware pipeline, what could be the potential reason?

  • The middleware order is incorrect.
  • The application is not running on a supported OS.
  • The middleware is not properly configured.
  • The server is overloaded.
In the ASP.NET Core middleware pipeline, the order in which middleware components are added matters. If the middleware order is incorrect, it can lead to unexpected behavior. Middleware components are executed in the order they are added to the pipeline.

The _______ attribute in ASP.NET Core MVC allows you to specify the route pattern directly on the controller or action method.

  • Route
  • Path
  • URL
  • Routing
The [Route] attribute in ASP.NET Core MVC allows you to specify the route pattern directly on the controller or action method. It is used to define the URL at which a particular controller or action should respond. This attribute is essential for defining custom routing patterns in your application.

Which of the following is essential for developing and running ASP.NET Core applications?

  • .NET Core SDK
  • A fancy keyboard
  • A high-resolution monitor
  • A fast internet connection
The essential component for developing and running ASP.NET Core applications is the .NET Core SDK (Software Development Kit). It provides the necessary tools, libraries, and runtime to build, test, and run ASP.NET Core applications on various platforms. Without it, ASP.NET Core development would be impossible.

In your ASP.NET Core application, you wish to change some default settings like the application's timezone and culture. Which file should you inspect and modify?

  • appsettings.json
  • Startup.cs
  • Program.cs
  • appconfig.xml
In ASP.NET Core, you typically configure application settings, including timezone and culture, in the appsettings.json file. This file allows you to centralize configuration settings for your application.

Which feature of EF Core allows developers to execute raw SQL commands directly against the database?

  • SQL Executor
  • SQL Raw Execute
  • Raw SQL Queries
  • ExecuteSQL
EF Core provides a feature called "Raw SQL Queries" that allows developers to execute raw SQL commands directly against the database. This feature is useful when you need to run complex or specific SQL queries that cannot be easily expressed using LINQ or the query builder methods provided by EF Core.

For a scenario where you want to return different types of responses (e.g., JSON or HTML) based on some conditions, which action result provides the flexibility to achieve this?

  • ContentResult
  • PartialViewResult
  • ObjectResult
  • ActionResult
The ActionResult action result provides the flexibility to return different types of responses based on conditions. It's a base class for other action results in ASP.NET Core, allowing you to return various derived result types like JsonResult, ViewResult, or ContentResult. Depending on your conditions, you can choose the appropriate derived result type to return different responses, such as JSON or HTML.

When performing unit testing in ASP.NET Core, what attribute is commonly used to signify a method as a test method?

  • [TestMethod]
  • [UnitTest]
  • [Test]
  • [TestFunction]
In ASP.NET Core unit testing, the [Test] attribute is commonly used to signify a method as a test method. This attribute is part of popular unit testing frameworks like MSTest and xUnit.

In ASP.NET Core Identity, what's the best way to customize the hashing algorithm used for storing passwords?

  • Implement a custom PasswordHasher
  • Modify the Startup.cs file
  • Use a third-party library
  • Edit the appsettings.json file
The best way to customize the password hashing algorithm in ASP.NET Core Identity is by implementing a custom PasswordHasher. This allows you to have full control over the hashing process, ensuring it meets your specific security requirements.

What is the primary role of Entity Framework Core in ASP.NET Core applications?

  • Object-Relational Mapping (ORM)
  • User Authentication
  • Web Hosting
  • Front-end Development
Entity Framework Core (EF Core) is primarily an Object-Relational Mapping (ORM) framework. It simplifies database operations by allowing developers to work with databases using object-oriented code, making it easier to interact with and manipulate data. User authentication, web hosting, and front-end development are unrelated to EF Core's core functionality.

You're working on an e-commerce platform and need to create a route for a product details page which takes a product ID as a parameter. Using attribute routing, how would you set up this route?

  • [Route("products/details/{id:int}")]
  • [HttpGet("products/details/{productID}")]
  • [Route("products/details")]
  • [Route("products/{id}")]
To set up a route for a product details page with a product ID parameter using attribute routing, you should use [Route("products/details/{id:int}")]. The ':int' constraint specifies that the 'id' parameter must be an integer.

To override the default routing conventions in MVC, you can use the _________ attribute on your action methods.

  • Route
  • Controller
  • Action
  • HTTPGet
To override the default routing conventions in ASP.NET Core MVC, you can use the "Route" attribute on your action methods. This attribute allows you to specify custom routing patterns, such as route templates and parameters, for fine-grained control over URL routing in your application.

The ________ method in the "Startup.cs" file is used to add and configure middleware services to the application's request pipeline.

  • ConfigureServices
  • Configure
  • UseMiddleware
  • AddMiddleware
In the "Startup.cs" file of an ASP.NET Core application, the "ConfigureServices" method is used to add and configure middleware services. Middleware services are components that handle requests and responses as they flow through the application's request pipeline. The "ConfigureServices" method is where you register services such as database connections, authentication, and dependency injection.
