Google Cloud Associate Data Practitioner — Question 9

Your company has developed a website that allows users to upload and share video files. These files are most frequently accessed and shared when they are initially uploaded. Over time, the files are accessed and shared less frequently, although some old video files may remain very popular.
You need to design a storage system that is simple and cost-effective. What should you do?

Answer options

• A. Create a single-region bucket with Autoclass enabled.
• B. Create a single-region bucket. Configure a Cloud Scheduler job that runs every 24 hours and changes the storage class based on upload date.
• C. Create a single-region bucket with custom Object Lifecycle Management policies based on upload date.
• D. Create a single-region bucket with Archive as the default storage class.

Correct answer: A

Explanation

The correct answer is A because enabling Autoclass allows the storage system to automatically manage the storage class based on object access patterns, optimizing costs over time. Option B requires manual intervention that adds complexity and might not be as efficient. Option C, while useful, does not offer the automatic adjustments that Autoclass provides. Option D is not ideal since Archive would be too costly for frequently accessed files.
