In the hierarchy of configuration sources, which source has the highest precedence in determining the final value of a configuration setting in ASP.NET Core?
- Environment Variables
- Command-Line Arguments
- JSON Configuration File
- User Secrets
In ASP.NET Core, configuration sources are considered in a specific order, with command-line arguments having the highest precedence. This means that if a configuration setting is provided via a command-line argument, it will override settings from other sources.
You are tasked with deploying an ASP.NET Core application. Which tool or service would help automate the process of getting new code from a developer's machine to a production environment?
- Jenkins
- Docker
- Azure DevOps
- Visual Studio Code
Azure DevOps is a comprehensive tool for automating the deployment pipeline. It facilitates the automation of code deployment from a developer's machine to a production environment, making it a valuable choice for ASP.NET Core application deployment.
In your new job, you're asked to ensure that user passwords are at least 8 characters long. Where in the ASP.NET Core Identity would you set this requirement?
- IdentityOptions
- Startup.cs
- AccountController.cs
- UserManager
In ASP.NET Core Identity, you can set password requirements like length using the IdentityOptions configuration in the Startup.cs file. This allows you to enforce policies such as minimum password length, special characters, and more.
What advantage does the "Web Application (Model-View-Controller)" template offer over the "Web Application" template in terms of structuring the application?
- It uses Angular for the front-end.
- It provides a clear separation of concerns with the MVC pattern.
- It has built-in authentication and authorization.
- It supports only RESTful APIs.
The "Web Application (Model-View-Controller)" template follows the MVC pattern, which enforces a clear separation of concerns between the model (data), view (presentation), and controller (logic). This separation makes it easier to manage and maintain the application as it grows in complexity. The "Web Application" template, on the other hand, may not enforce this separation as strictly.
If you want to code for ASP.NET Core and prefer a lightweight, cross-platform editor, which tool would you likely use?
- Visual Studio
- JetBrains Rider
- Sublime Text
- Visual Studio Code
If you prefer a lightweight, cross-platform editor for coding ASP.NET Core applications, Visual Studio Code is an excellent choice. It offers a wide range of extensions and supports various programming languages, making it a popular choice among developers for web development, including ASP.NET Core.
Your application needs to restrict access based on the originating country of the request. How would you leverage middleware to achieve this requirement?
- Use GeoIP databases within a custom middleware
- Implement authorization policies
- Create a filter attribute for country-based access
- Modify the routing system
To restrict access based on the originating country of a request, you would typically use a custom middleware that utilizes GeoIP databases. This middleware can inspect the incoming request's IP address, determine the country, and then make access decisions accordingly. Authorization policies are more suitable for handling user roles and permissions, not geographical restrictions.
In ASP.NET Core, the _______ tag helper can be used to generate anchor (link) elements that link to MVC actions.
- a
- link
- action
- route
In ASP.NET Core, the a tag helper is used to generate anchor (link) elements that link to MVC actions. It simplifies the creation of hyperlinks to various parts of your application, making it easier to navigate between views and actions.
Where in an ASP.NET Core project would you typically find database migration files?
- Controllers
- Data
- Models
- Services
In an ASP.NET Core project, you would typically find database migration files in the "Data" folder. Database migration files are used to manage changes to the database schema over time. They define how the database structure evolves with updates to the application, making it easier to keep the database schema in sync with the application's requirements.
Which of the following is NOT a default template option when creating a new ASP.NET Core project?
- Web API, Razor Pages, Windows Forms, Angular
- Empty, Web API, Web Application, Blazor
- Class Library, Console Application, Unit Test Project, Worker Service
- None of the above
When creating a new ASP.NET Core project, "Windows Forms" is not a default template option. ASP.NET Core primarily focuses on web-based and cloud-based applications, so options like Web API, Razor Pages, and Blazor are more common project types.
What is the significance of the @model directive in a Razor view?
- Specifies the layout of the view
- Defines the model class for the view
- Imports external libraries
- Declares a variable
The @model directive in a Razor view specifies the model class that the view expects to receive. It allows you to strongly type the view, enabling compile-time checking and intellisense for model properties in the view. This helps prevent runtime errors and improves code maintainability.
