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 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.

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.

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.

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 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.

In SignalR, what term is used to describe a group of connections that can be broadcast to?

  • Hub
  • Cluster
  • Node
  • Router
In SignalR, a "Hub" is used to describe a group of connections that can be broadcast to. Hubs provide a high-level API for organizing connections and managing communication between clients and the server in real-time applications.

You want to develop a web application that can run seamlessly on both Linux and Windows without modifying the codebase. Why might ASP.NET Core be suitable for this task?

  • Cross-Platform Compatibility
  • Windows-Only Features
  • Legacy Code Integration
  • Proprietary Licensing
ASP.NET Core's primary advantage in this scenario is its cross-platform compatibility. It allows you to develop a web application that seamlessly runs on both Linux and Windows without the need for codebase modifications. This flexibility is especially valuable when targeting multiple platforms and ensuring a consistent user experience across them.

You're reviewing a colleague's code and notice that they've added the same namespace to multiple Razor views. How can you suggest an optimization to this approach?

  • Leave it as is, it's the standard practice
  • Suggest moving the namespace declaration to the _Layout.cshtml file
  • Suggest moving the namespace declaration to the _ViewImports.cshtml file
  • Remove the namespace declaration altogether
The optimization suggestion would be to move the common namespace declaration to the _ViewImports.cshtml file. This way, it's defined once and is available for all views, reducing redundancy and making it easier to manage.

In SignalR, which transport method does it fall back to if WebSockets are not available?

  • Server-Sent Events (SSE)
  • Long Polling
  • WebRTC
  • gRPC
SignalR is a real-time framework for ASP.NET Core that supports various transport methods. When WebSockets are not available due to network restrictions or browser compatibility, SignalR falls back to Long Polling. Long Polling involves sending a request to the server, keeping it open until new data is available, and then responding.
