For ensuring that the test runs in isolation, real services or components might be replaced with _________ during unit testing.
- Mocks
- Stubs
- Dummies
- Fakes
During unit testing, real services or components that are external to the unit being tested are often replaced with mocks or stubs. Mocks provide controlled behavior for testing without relying on the actual implementations of these external components.
What is the primary difference between the _ViewImports.cshtml and _ViewStart.cshtml files in Razor?
- _ViewImports.cshtml sets directives and namespaces
- _ViewStart.cshtml sets layout and common code
- They serve the same purpose
- _ViewStart.cshtml sets routing rules
The primary difference between _ViewImports.cshtml and _ViewStart.cshtml in Razor is their purpose. _ViewImports.cshtml is used to set directives, namespaces, and base class declarations for views, whereas _ViewStart.cshtml is used to specify common layout code and execute code before rendering views. _ViewStart.cshtml is typically used to set layout and execute code that should apply globally to multiple views.
When securing your ASP.NET Core Web APIs, which authentication approach uses a compact, URL-safe means of representing claims to be transferred between two parties?
- OAuth 2.0
- JSON Web Tokens (JWT)
- SAML (Security Assertion Markup Language)
- OpenID Connect
JSON Web Tokens (JWT) is an authentication approach commonly used in ASP.NET Core Web APIs. JWTs are compact and URL-safe, making them efficient for transferring claims between parties. They provide a secure way to represent user identities and access permissions.
You're building a simple website using ASP.NET Core. You want to display a friendly error page when something goes wrong in your application. What's the standard way to do this in ASP.NET Core?
- Custom Error Page
- Detailed Logging
- Exception Handling Middleware
- Using Console.WriteLine()
The standard way to display a friendly error page in ASP.NET Core is by using Exception Handling Middleware. This middleware captures unhandled exceptions and can be configured to display custom error pages, making it easier for users to understand what went wrong.
In a project where user registration is done programmatically, you want to ensure that users have a strong password and are locked out after 5 incorrect login attempts. Which class should you configure to enforce these rules?
- IdentityUser
- IdentityRole
- PasswordHasher
- IdentityOptions
To enforce password strength rules and configure account lockout settings, you should configure the IdentityOptions class. This class allows you to set various security-related options, including password complexity requirements and account lockout thresholds.
Which Razor directive is typically used at the beginning of a view file to specify its layout page?
- @layout
- @page
- @model
- @section
The @layout Razor directive is used at the beginning of a view file to specify its layout page in ASP.NET Core MVC. It allows you to define the layout that should be applied to the current view, providing a consistent structure for your web pages.
Your team is implementing a Continuous Integration (CI) pipeline for an ASP.NET Core application. What is the main reason for integrating automated tests into this CI pipeline?
- Ensure Code Quality
- Speed Up Deployment
- Reduce Server Costs
- Simplify Documentation
The main reason for integrating automated tests into a CI pipeline is to ensure code quality. Automated tests help catch bugs early in the development process, improve the reliability of the application, and provide confidence that changes won't introduce regressions. This ultimately leads to a higher-quality product.
Which file in an ASP.NET Core project acts as the entry point of the application?
- Startup.cs
- Program.cs
- appsettings.json
- Controller.cs
In an ASP.NET Core project, the "Program.cs" file serves as the entry point of the application. It contains the Main method, which creates the web host and starts the application. This is where the application configuration and host building occur before the application starts listening for incoming requests.
In which part of an MVC application would you typically find attribute routes?
- Controller Actions
- Views
- Models
- Middleware
Attribute routes are typically found in Controller Actions within an MVC application. Controllers use attribute routing to define custom routes for their action methods, which can be more readable and maintainable than convention-based routing.
You are building a small website using ASP.NET Core MVC. For displaying data to the users, which component of the MVC pattern should you focus on?
- Model
- View
- Controller
- Routing
In the MVC (Model-View-Controller) pattern, the "View" component is responsible for displaying data to users. It defines the structure and layout of the web pages, presenting data from the model in a user-friendly format. Controllers handle the request processing, but views handle the presentation of data to the users.
