Google Professional Cloud Developer Question 437
Single answerGoogle Cloud PlatformYou are developing a cloud-native application on Google Cloud that needs to interact with the Cloud Storage API to list and download files from a storage bucket. Your team has decided to prioritize performance and reduce the amount of manual work required for API integration. Which method should you use to implement this functionality?
- A
Use the Cloud Client Library for your programming language.
- B
Manually craft HTTP requests to the REST API using a custom HTTP client.
- C
Use the API Explorer to execute API calls directly.
- D
Use the gRPC API for Cloud Storage.
Show answer and explanation
Correct answer: A
Explanation
The Cloud Client Library is the most efficient and developer-friendly method for interacting with Google Cloud APIs, including Cloud Storage. It provides high-level abstractions, handles authentication seamlessly, and is designed to integrate well with the supported programming languages. This makes it the ideal choice for implementing functionality like listing and downloading files from a storage bucket.
- A. Correct.
The Cloud Client Library is the recommended option for most use cases since it is optimized for performance, follows idiomatic language patterns, and provides built-in authentication and simplified API calls.
- B. Incorrect.
Manually crafting HTTP requests to the REST API introduces unnecessary complexity and is error-prone. This approach is not recommended unless there is a very specific need.
- C. Incorrect.
The API Explorer is primarily a tool for testing and exploring APIs interactively. It is not designed for programmatic use in production applications.
- D. Incorrect.
Cloud Storage does not provide a gRPC API. This option is invalid for this specific use case.
