Google ACE Planning and Configuring a Cloud Solution Practice Question
A developer needs to create a Cloud Storage bucket that stores data for only 30 days and then automatically deletes it. Which feature should be used to achieve this?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Object lifecycle management
Object lifecycle management rules can automatically delete objects after a specified age. Bucket lock is for retention compliance, not deletion. Versioning keeps multiple versions. Requester pays shifts costs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Object versioning
Why it's wrong here
Object versioning keeps multiple versions of an object whenever it is created, overwritten, or deleted, enabling recovery from accidental changes. It does not automatically prune old versions unless you explicitly configure lifecycle rules targeted at noncurrent versions. By itself, versioning preserves all versions indefinitely and cannot delete objects after 30 days, making it the wrong tool for this task.
- ✗
Requester pays
Why it's wrong here
Requester Pays is a billing setting that shifts network egress and operation costs from the bucket owner to the requesting client. It only affects who pays for access, not how long objects are stored or when they are removed. Enabling it would not cause any objects to be automatically deleted after 30 days, so it is not the correct mechanism.
- ✓
Object lifecycle management
Why this is correct
Object Lifecycle Management is a native Cloud Storage feature that lets you define rules to automatically delete or transition objects based on conditions like age. A rule with action 'Delete' and condition 'Age: 30 days' will remove objects that are at least 30 days old. This directly satisfies the developer's requirement for scheduled deletion, making it the correct choice.
- ✗
Bucket lock
Why it's wrong here
Bucket Lock is designed to enforce retention policies that prevent objects from being deleted or overwritten for a specified minimum duration, supporting WORM (write once, read many) compliance. It does not trigger deletion; instead, it protects data from removal while the retention policy is active. Applying a bucket lock would block the intended automatic deletion after 30 days, so it is incorrect here.
