Your data team is developing new machine learning models and generates several files daily, storing them in a regional bucket. They primarily access files from the last week but wish to retain all files for occasional monthly reference. What is the most efficient method to reduce storage costs?
Explanation:
The correct answer is D because Nearline storage is cost-effective for files accessed once a month, aligning with the team's needs. Object Lifecycle Management simplifies the transition process. Coldline storage (Option C) is less cost-effective for monthly access. Options A and B are inefficient as lifecycle management automates transitions without the need for Cloud Functions.
