When you attempt to create a user programmatically in ASP.NET Core, and the creation fails, what type of object can be checked to obtain the reasons for the failure?
- IdentityResult
- ApplicationUser
- UserManager
- RoleManager
When creating a user programmatically using ASP.NET Core Identity, the CreateAsync method typically returns an IdentityResult object.

You're setting up a new ASP.NET Core project, and you specifically need a template that provides user authentication out of the box. Which template should you select during the project setup?
- Empty
- Individual User Accounts
- MVC
- Web API
To set up a new ASP.NET Core project with built-in user authentication, you should choose the "Individual User Accounts" template. This template provides user registration, login, and other authentication-related features right from the start, saving you development time.
In which type of testing do you test individual components or units of software in isolation?
- Integration Testing
- System Testing
- End-to-End Testing
- Unit Testing
Unit testing is the practice of testing individual components or units of software in isolation from the rest of the application. It helps identify issues within these units before integrating them into the larger system.
How can you override the default layout specified in the _ViewStart.cshtml for a specific Razor view?
- Using the @layout directive in the view
- By modifying the _ViewStart.cshtml file
- By setting the layout property in the controller
- By using the @section directive

When creating a custom Tag Helper, which class should it derive from?
- TagHelper
- Controller
- RazorPage
- Model

Your application uses ASP.NET Core Identity for authentication. During the security audit, it was pointed out that the application should enforce password reset every 90 days. How can you enforce this in ASP.NET Core?
- Configure password expiration in IdentityOptions
- Create a custom middleware to force password reset
- Implement a password reset policy in the login controller
- Use a third-party identity management library
To enforce password reset every 90 days in ASP.NET Core Identity, you should configure the password expiration policy in the IdentityOptions during application startup. This policy can be set to require users to change their passwords after a specified number of days.
In a CI/CD pipeline, what does the acronym CI stand for?
- Continuous Integration
- Continuous Inspection
- Continuous Improvement
- Container Isolation
CI stands for Continuous Integration. It's a development practice where code changes are automatically built, tested, and integrated into the shared codebase frequently. This helps detect and fix integration issues early in the development process.
You're working on an ASP.NET Core project where the client needs real-time updates from the server without constantly polling the server. Which technology in ASP.NET Core would you leverage?
- SignalR
- gRPC
- WebSockets
- REST API
In this scenario, you would leverage SignalR, which is a real-time communication library for ASP.NET Core. SignalR allows for bi-directional communication between the client and server, making it ideal for scenarios where you need real-time updates without the overhead of constant polling.
In ASP.NET Core Identity, the _________ method is used to authenticate a user with provided credentials.
- SignInAsync
- AuthenticateUser
- AuthorizeUser
- CheckCredentials
In ASP.NET Core Identity, the SignInAsync method is used to authenticate a user with provided credentials. This method handles the process of validating the user's username and password against the stored user data in the Identity system. It creates a security token for the authenticated user, allowing them access to protected resources.
Which ASP.NET Core middleware is responsible for enabling session state in the application?
- app.UseRouting
