QuestionQ147

Integrating applications with Google Cloud services

You are building a new public-facing application that must retrieve particular properties from the metadata of users’ objects in their respective Cloud Storage buckets. Because of privacy and data-residency requirements, you must retrieve metadata only, not object data. You want to maximize retrieval performance. How should you retrieve the metadata?

  • A Use the patch method.
  • B Use the compose method.
  • C Use the copy method.
  • D Use the fields request parameter.
Explanation

The Cloud Storage JSON API fields request parameter requests a partial response containing only the specified metadata properties, reducing response payload and improving retrieval performance without returning object data.
