Imagine you're developing an ASP.NET Core application on a machine without any internet access. Which tool, among the following, allows you to install NuGet packages from a local feed or folder?
- Visual Studio
- dotnet CLI
- NuGet Package Manager Console
- Visual Studio Code
The dotnet CLI (Command-Line Interface) allows you to install NuGet packages from a local feed or folder. It provides the dotnet add package command, which supports specifying package sources. This is particularly useful when working in an offline environment or when you want to use custom package sources.
You are new to ASP.NET Core development and are setting up your computer for the first time. What would be the primary software you'd need to install to get started?
- Visual Studio Code
- .NET SDK
- SQL Server
- Adobe Photoshop
To get started with ASP.NET Core development, the primary software you need to install is the .NET SDK (Software Development Kit). This kit includes the necessary tools, libraries, and runtime environments to build, test, and run ASP.NET Core applications. Visual Studio Code is a popular code editor but does not include all the components required for ASP.NET Core development.
Which of the following best describes where you would apply the [Authorize] attribute?
- Above the class definition for global authorization
- Above the method that requires authorization
- Within the Startup.cs file
- In the web.config file
The [Authorize] attribute should be applied above the method that requires authorization. This means you place it directly above the action method within a controller where you want to restrict access. This approach allows for fine-grained control over which actions are protected and who can access them, ensuring security at the method level.
For API versioning in routing, what is the recommended approach in ASP.NET Core?
- Use query parameters for versioning
- Include version in the request headers
- Embed version in the route URL
- Use custom HTTP headers for versioning
The recommended approach for API versioning in ASP.NET Core is to embed the API version in the route URL. This approach is commonly referred to as "URI versioning" and provides clear versioning information within the request URL, making it easy for developers and clients to understand and use different API versions.
What is the primary purpose of the Startup.cs file in an ASP.NET Core application?
- Managing database connections
- Defining routes and handling HTTP requests
- Storing application settings
- Handling user authentication
The primary purpose of the Startup.cs file is to configure the application's request handling pipeline. It defines how HTTP requests are processed, which controllers and actions handle them, and how various middleware components are configured. Additionally, it sets up services, defines routes, and performs other initialization tasks necessary for the application to run.
For more advanced configurations, developers can make use of the _________ method inside the DbContext to execute any arbitrary SQL commands.
- Sql
- ExecuteSql
- Query
- ExecuteSqlCommand
In Entity Framework Core, developers can use the ExecuteSqlCommand method inside the DbContext to execute arbitrary SQL commands. This is especially useful for advanced configurations, data migrations, or when you need to perform database operations that are not supported by LINQ.
You've been tasked with updating the user table to include a new field for "MiddleName." After adding this field to the appropriate model class, what would be the next step to ensure the database is updated?
- Run dotnet ef migrations add
- Manually update the database schema
- No further steps are required
- Run dotnet build
After adding the new field to the model class, you should run the dotnet ef migrations add command to generate a new migration. This migration will contain the necessary changes to update the database schema. Manually updating the schema is not recommended as it can lead to inconsistencies.
For securing APIs in ASP.NET Core, which authentication method is recommended?
- Basic Authentication
- Windows Authentication
- Token-based Authentication
- Digest Authentication
For securing APIs in ASP.NET Core, token-based authentication is recommended. Token-based authentication, often using technologies like OAuth 2.0 or JWT (JSON Web Tokens), provides a secure and scalable way to authenticate and authorize users for API access. It's widely adopted for modern API security scenarios.
While configuring your entity models, you come across a method named OnModelCreating. What's the main purpose of this method in Entity Framework Core?
- It's used to define the structure and relationships of your entity models.
- It's used to create a new database schema.
- It's used to run SQL queries.
- It's used to define connection strings.
The OnModelCreating method in Entity Framework Core is used to define the configuration of your entity models, including their structure, relationships, and constraints. It allows you to customize how your entity classes are mapped to database tables, set up primary and foreign key relationships, and specify other configuration options. This method is essential for shaping the database schema that corresponds to your entity model.
Your manager mentioned using containers for deployment to ensure the application runs consistently across different environments. Which tool is commonly associated with this approach?
- Kubernetes
- Git
- Apache Tomcat
- NuGet
Kubernetes is a widely-used container orchestration platform that is often associated with containerized deployments, including ASP.NET Core applications. It helps manage containers, scaling, and ensuring consistent application behavior across different environments.
