What should you do?

You work for an organization in a regulated industry that has strict data protection requirements. The organization backs up their data in the cloud. To comply with data privacy regulations, this data can only be stored for a specific length of time and must be deleted after this specific period.

You want to automate the compliance with this regulation while minimizing storage costs.

What should you do?
A . Store the data in a persistent disk, and delete the disk at expiration time.
B . Store the data in a Cloud Bigtable table, and set an expiration time on the column families.
C . Store the data in a BigQuery table, and set the table’s expiration time.
D . Store the data in a Cloud Storage bucket, and configure the bucket’s Object Lifecycle
Management feature.

Answer: D

Explanation:

To miminize costs, it’s always GCS even though BQ comes as a close 2nd. But, since the question did not specify what kind of data it is (raw files vs tabular data), it is safe to assume GCS is the preferred option with LifeCycle enablement.
