What is the command to download and install the dependencies of a Go module?

  • go install
  • go get
  • go download
  • go mod tidy
The command to download and install the dependencies of a Go module is go get. When you run go get, it reads the dependencies from the go.mod file of the current module and downloads them into your project's GOPATH. This command also updates the go.sum file to ensure the security and integrity of the downloaded packages. It's a common practice to use go get to fetch and manage dependencies in Go projects.

What considerations would you take into account when designing the URI scheme of a RESTful API?

  • Use descriptive resource names.
  • Include sensitive data in URIs.
  • Use query parameters for all filtering and sorting needs.
  • Avoid using hierarchical URIs.
When designing the URI scheme of a RESTful API, using descriptive resource names is a best practice. It makes the API more intuitive and understandable for clients. Including sensitive data in URIs is generally a security risk and should be avoided. Instead, sensitive data should be sent in the request body or headers. Using query parameters for filtering and sorting is a common practice as it keeps the URIs cleaner and allows clients to specify their filtering criteria. Avoiding hierarchical URIs is not a general best practice, as hierarchical structures can be useful in representing relationships between resources.

In a high-traffic web application, how would you optimize the routing process to ensure efficient handling of HTTP requests?

  • Use wildcard routes for all routes to minimize routing tree complexity.
  • Implement caching of route matching results to reduce lookup times.
  • Utilize a single monolithic routing handler to process all incoming requests.
  • Enable routing tracing to log every route match for performance analysis.
In a high-traffic web application, optimizing routing is crucial for efficient request handling. Implementing caching of route matching results can significantly reduce lookup times. By storing the results of route matching in memory, subsequent requests can be quickly routed without repeatedly traversing the routing tree. This reduces CPU usage and improves response times. Using wildcard routes or a monolithic routing handler can lead to increased complexity and reduced performance, making them less suitable for high-traffic scenarios. Routing tracing, while useful for debugging, can introduce unnecessary overhead in production environments.

What is the primary purpose of Protocol Buffers?

  • To compress data for storage.
  • To serialize structured data efficiently.
  • To define database schemas.
  • To encrypt data in transit.
Protocol Buffers, also known as protobuf, are a method for serializing structured data in a compact, efficient, and language-agnostic way. Its primary purpose is efficient data serialization and deserialization, making it suitable for use cases like network communication, data storage, and data interchange between different systems and languages. Protocol Buffers are not specifically designed for data compression or encryption but rather for defining a schema and serializing data in a way that allows for efficient storage and transmission.

How do you specify a specific version of a dependency using Go Modules?

  • Using the 'require' directive
  • Using the 'replace' directive
  • Using the 'exclude' directive
  • Using the 'import' directive
To specify a specific version of a dependency using Go Modules, you use the 'require' directive in the go.mod file. You list the module path and the desired version, ensuring that the version adheres to semantic versioning (SemVer). This allows Go Modules to fetch the correct version of the dependency when you build your project. This precise versioning is essential for ensuring consistency and predictability in your project's dependencies.

You're trying to create a basic form in a Razor view to capture user feedback. Which tag helper would you use to create a textbox for users to type in their comments?

  • asp-input
  • asp-textbox
  • asp-text
  • asp-form
To create a textbox for user input in a Razor view, you would use the asp-textbox tag helper. This helper generates the necessary HTML input element, and you can specify its attributes and bindings using the asp-for attribute. It's a handy tool for creating forms in ASP.NET Core views.

You notice that despite having a "Details" action method in your "Products" controller, navigating to "/Products/Details/5" results in a 404 error. What could be a probable cause?

  • Incorrect route configuration
  • Missing View file
  • Authorization issues
  • Database connectivity issues
The most probable cause of a 404 error when accessing an action method is incorrect route configuration. Ensure that the route for the "Details" action method in the "Products" controller is properly configured to accept the required parameters, such as the product ID (e.g., "{controller}/{action}/{id}").

Which method in Entity Framework Core is primarily used for tracking changes made to an entity?

  • Update
  • Add
  • Attach
  • Remove
The Attach method in Entity Framework Core is primarily used for tracking changes made to an entity. When you attach an entity, EF Core starts tracking it, and any changes made to that entity will be detected and persisted when you call SaveChanges. This is especially useful when you want to work with entities that have been detached from the context.

How does ASP.NET Core maintain its modularity compared to its predecessor?

  • Through NuGet Packages
  • Through a Monolithic Architecture
  • Through Tight Coupling
  • Through Proprietary Components
ASP.NET Core achieves modularity through the extensive use of NuGet packages. This means that various components and libraries are organized as packages, making it easy to update, replace, or extend specific parts of the framework without affecting the entire application. This is a significant departure from the monolithic architecture of its predecessor, which had tightly coupled components and fewer modular options.

ASP.NET Core is a successor to which of the following frameworks?

  • ASP.NET MVC
  • ASP.NET Web Forms
  • Classic ASP
  • PHP
ASP.NET Core is a successor to the ASP.NET MVC framework. While ASP.NET Web Forms and Classic ASP were earlier web development technologies from Microsoft, ASP.NET Core represents a more modern and flexible approach to web development.

What is the primary purpose of the Register action in a typical ASP.NET Core Identity controller?

  • Allowing users to log in
  • Handling user registration
  • Managing user profiles
  • Deleting user accounts
The primary purpose of the Register action in an ASP.NET Core Identity controller is to handle user registration. It processes user-provided information, such as username, password, and email, and creates a new user account in the system, allowing them to log in subsequently.

What purpose do Razor Tag Helpers serve in ASP.NET Core?

  • Simplify server-side code in Razor views
  • Generate CSS styles
  • Handle routing in controllers
  • Create REST APIs
Razor Tag Helpers in ASP.NET Core simplify server-side code in Razor views by providing a more natural way to work with HTML elements and attributes. They make it easier to integrate server-side logic into your views while maintaining clean and readable code.
