Have the vehicle's computer compress the data in hourly snapshots, and store it in a GCS Coldline bucket
Answers
D.
Have the vehicle's computer compress the data in hourly snapshots, and store it in a GCS Coldline bucket
Suggested answer: D

Explanation:

Storage is the best choice for data that you plan to access at most once a year, due to its slightly lower availability, 90-day minimum storage duration, costs for data access, and higher per-operation costs. For example:

Cold Data Storage - Infrequently accessed data, such as data stored for legal or regulatory reasons, can be stored at low cost as Coldline Storage, and be available when you need it.

Disaster recovery - In the event of a disaster recovery event, recovery time is key. Cloud Storage provides low latency access to data stored as Coldline Storage. References: https://cloud.google.com/storage/docs/storage-classes
