GCP PCA · Question 49 · Domain 5: Managing Implementation and Ensuring Solution and Operations Reliability

You are advising a development team on how to optimize their Cloud Storage costs. They have a bucket containing millions of user-uploaded documents. Documents are accessed frequently for the first 30 days, occasionally between 30 and 90 days, and almost never after 90 days, but must be kept for 7 years for compliance. Which TWO actions should you take? (Select TWO)

Answer options:

A.

Set the default storage class of the bucket to Standard.

B.

Set the default storage class of the bucket to Archive.

C.

Create a Lifecycle Rule to transition objects to Nearline after 30 days, and to Archive after 90 days.

D.

Write a Cloud Function to zip the files after 90 days.

E.

Use Persistent Disk snapshots for long-term retention.

How to approach this question

Match the storage classes to the access frequency timeline, and use automation to move the data.

Full Answer

To optimize Cloud Storage costs, you must match the storage class to the access pattern. The bucket should default to Standard storage (Option A) for the frequent access in the first 30 days. You should then implement a Cloud Storage Lifecycle Policy (Option C) to automatically transition the objects to Nearline (for occasional access) after 30 days, and finally to Archive (for long-term compliance retention) after 90 days.

Common mistakes

Choosing B. If you default to Archive, every read in the first 30 days incurs a high retrieval fee, costing more than Standard storage.
