What this topic is really about
Cloud Storage bucket names reside in a single global namespace, meaning every bucket name must be globally unique across all of Google Cloud. They cannot be duplicated in another project or region, making options C and D incorrect. This ensures that the public URL of the bucket remains unique.
Archive storage is the lowest-cost, highly durable class designed for data accessed less than once a year, making it ideal for long-term backups. Standard storage, by contrast, is optimized for frequently accessed data and does not incur retrieval fees but has higher storage costs.
