Which command is commonly used to create a new migration for ASP.NET Core Identity changes?

  • dotnet ef migrations add
  • dotnet new migration
  • dotnet ef create migration
  • dotnet add migration
The commonly used command to create a new migration for ASP.NET Core Identity changes is 'dotnet ef migrations add'. This command generates a new migration file containing the necessary SQL scripts to update the database schema based on changes in your Identity-related code.

Your organization wants to implement a deployment pipeline where every code change goes through a series of automated tests and, if successful, gets deployed to production automatically. What kind of deployment strategy is your organization aiming for?

  • Continuous Deployment (CD)
  • Blue-Green Deployment
  • Canary Deployment
  • Feature Toggles
Continuous Deployment (CD) is a deployment strategy where code changes are automatically deployed to production after passing automated tests. It enables rapid and reliable software delivery, ensuring that new features and bug fixes are quickly available to users.

Which of the following would NOT typically be found in the project.json file?

  • Target Framework Monikers
  • NuGet Package Dependencies
  • Build Scripts
  • Compiler Options
The "Build Scripts" would NOT typically be found in the project.json file. Project.json primarily focused on project structure, dependencies, and target frameworks, whereas build scripts were typically defined in other build-related files or tools specific to the build system.

How did project.json handle transitive dependencies differently than the NuGet approach in previous ASP.NET versions?

  • Implicitly
  • Explicitly
  • No Transitive Dependencies
  • Manually
Project.json handled transitive dependencies explicitly, meaning it included both direct and transitive dependencies in the project file. In contrast, the NuGet approach in previous ASP.NET versions handled transitive dependencies implicitly, which required developers to manage them manually. Project.json's explicit handling improved transparency and control over dependencies.

You are developing an e-commerce site where user's cart information needs to be preserved across sessions even if they log out. How can you achieve this in ASP.NET Core?

  • Use browser cookies to store cart data
  • Utilize Session state with server-side storage
  • Store cart data in a client-side cookie
  • Use local storage in JavaScript
To preserve the user's cart information across sessions, even after they log out, you should utilize Session state with server-side storage. This allows the cart data to be stored on the server, making it persistent across user sessions.

You've been reading about the MVC architecture and are trying to understand the components. If you wanted to add logic to fetch data from a database when a user visits a certain page, which component of MVC would handle this?

  • Model
  • View
  • Controller
  • Middleware
In the MVC (Model-View-Controller) architecture, the 'Model' component handles data-related logic, such as fetching data from a database. It represents the application's data and business logic. The 'Controller' handles user input and coordinates the flow of data between the 'Model' and 'View' components.

You've created a new ASP.NET Core application with user registration. Now, you want to ensure that only registered users can post comments. Which attribute would you use to implement this restriction?

  • [AllowAnonymous]
  • [Authorize]
  • [Authorize(Roles = "Admin")]
  • [Authorize(Roles = "User")]
To restrict access to registered users only, you would use the [Authorize] attribute. This attribute can be applied at the controller or action level and ensures that only authenticated users can access the specified resources. It doesn't require specifying roles, as it already implies authenticated users. [AllowAnonymous] would allow both anonymous and registered users, while [Authorize(Roles = "Admin")] and [Authorize(Roles = "User")] are role-based authorizations and are not suitable for this scenario.

You are new to web development and you've heard about ASP.NET Core. What is the primary language used to code in this framework?

  • C#
  • Java
  • Python
  • Ruby
The primary language used for coding in ASP.NET Core is C#. While ASP.NET Core supports multiple languages, C# is the most commonly used language for building ASP.NET Core applications due to its strong integration with the framework and extensive tooling support.

What does the Identity middleware in ASP.NET Core primarily handle?

  • Authentication
  • Data Storage
  • Audio Processing
  • Weather Forecasting
The Identity middleware in ASP.NET Core primarily handles authentication. It intercepts requests to determine if a user is authenticated and provides features like cookie-based authentication, token-based authentication, and integration with external identity providers (e.g., Google, Facebook) for user login.

In the MVC design pattern, which component is primarily responsible for handling user input and interactions?

  • Model
  • View
  • Controller
  • Database
In the MVC (Model-View-Controller) design pattern, the Controller is primarily responsible for handling user input and interactions. It receives user requests, processes them, interacts with the Model to retrieve or manipulate data, and determines the appropriate View to render as a response.

Imagine you're working on an e-commerce application using ASP.NET Core MVC. A user wants to view details of a product. Which component of the MVC pattern would be responsible for fetching the product details from the database?

  • Model
  • View
  • Controller
  • Middleware
In the MVC (Model-View-Controller) pattern, the Model component is responsible for managing the application's data and business logic. In this scenario, it would be responsible for fetching the product details from the database. The Model interacts with the database and provides data to the Controller, which then passes it to the View for rendering.

You've been asked to add a feature to your ASP.NET Core web application that allows live chat functionality. Which ASP.NET Core technology would help facilitate this feature?

  • SignalR
  • Entity Framework Core
  • ASP.NET Web Forms
  • Blazor
SignalR is a real-time web framework in ASP.NET Core that enables features like live chat. It allows bi-directional communication between the server and connected clients, making it ideal for building interactive and real-time applications. The other options are not related to live chat functionality.
