Google Professional Cloud Developer Question 435
Single answerGoogle Cloud PlatformYou are developing a serverless application on Google Cloud that needs to interact with Cloud Storage to upload and retrieve objects. The application must minimize development effort and use idiomatic libraries for better developer productivity. Which approach should you choose to make API calls to Cloud Storage?
- A
Use the Cloud Client Library for Cloud Storage.
- B
Use the REST API for Cloud Storage by sending HTTP requests manually.
- C
Use the gRPC interface provided by Cloud Storage.
- D
Use the API Explorer to generate code snippets for Cloud Storage operations.
Show answer and explanation
Correct answer: A
Explanation
The Cloud Client Library for Cloud Storage is the best choice because it offers a high-level, idiomatic, and developer-friendly interface to interact with the service. It abstracts away the complexity of making raw HTTP calls and integrates easily with Google Cloud authentication, making it the most efficient and maintainable option for this scenario.
- A. Correct.
The Cloud Client Library is the recommended method for interacting with Google Cloud services, including Cloud Storage. It is idiomatic, integrates well with Google Cloud's authentication mechanisms, and minimizes development effort.
- B. Incorrect.
While the REST API is a valid option, it requires manually constructing HTTP requests and handling responses, which increases development effort and potential for errors.
- C. Incorrect.
Cloud Storage does not provide a gRPC interface. It primarily offers REST APIs and client libraries for interaction.
- D. Incorrect.
API Explorer is a tool for testing and exploring APIs but is not intended for production-level development or integration into applications.
