GCP Professional Cloud Architect Practice Question

Your team stores environment configuration files in a single Cloud Storage bucket. A CI/CD job overwrites several of these JSON files many times per day. Occasionally a bad deployment overwrites a file with incorrect contents, and engineers need the ability to roll back to any previous copy quickly. They also want to limit additional storage costs by removing obsolete copies after 30 days. Which single bucket configuration change best satisfies these requirements?

  • Enable Object Versioning on the bucket and add an Object Lifecycle Management rule that deletes noncurrent object versions older than 30 days.

  • Apply a 30-day bucket retention policy and place temporary holds on objects to prevent deletion during that period.

  • Change the bucket's default storage class to Nearline and require the CI/CD pipeline to save each update under a unique object name.

  • Enable Cloud Storage access logging to a separate bucket and use the logs to reconstruct previous versions of the overwritten files.
