Follow D

I believe the answer is actually B, and D won't cut it. D does not address the need "Documents must be kept for five years." A retention policy is required, otherwise someone can just delete a document. Someone else suggested that you can't set object versioning with life cycle rules, but that's not quite true. https://cloud.google.com/storage/docs/lifecycle You can, but it does require object versioning to be enabled... So none of these answers are ideal, but I think the omission of setting a retention policy explicitly misses the first requirement stated.

The correct answer is **D. Enable object versioning on the bucket, use lifecycle conditions to change the storage class of the objects, set the number of versions, and delete old files**. Here's why: - **Object versioning** allows you to keep up to five revisions of the same invoice document. - **Lifecycle conditions** can be used to automatically change the storage class of objects older than 365 days to a lower-cost storage tier. - You can also set the number of versions to keep and automatically delete old files, which helps to manage storage costs effectively. This approach aligns with Google-recommended practices and helps to minimize operational and development costs.

Obvious answer is D

- Object Versioning: Enabling object versioning on the Cloud Storage bucket allows you to store up to five revisions of the same invoice document. This satisfies the requirement for keeping multiple versions of each document for corrections. - Lifecycle Conditions: Google Cloud Storage allows you to define lifecycle conditions for objects within a bucket. These conditions can automatically change the storage class of objects when they meet certain criteria, such as age. After 365 days, you can automatically move documents to lower-cost storage classes like Nearline, Coldline, or Archive, which reduces storage costs while still retaining the data. - Version Management and Deletion: The lifecycle rules can also be configured to manage the number of object versions retained and to delete old versions or objects, ensuring compliance with the five-year retention requirement.

Per ChatGPT, Option D aligns with Google-recommended practices for managing objects in Cloud Storage, including versioning, lifecycle management, and cost optimization, making it the best choice for the given scenario.

D. Enable object versioning on the bucket, use lifecycle conditions to change the storage class of the objects, set the number of versions, and delete old files.
