Difficulty: HardPlanning Cloud Storage Buckets and Storage Classes

A broadcast television network is migrating its video catalog to Google Cloud Storage. The media production team defines two distinct lifecycle phases for video assets:
1. Active Editing Phase: Newly recorded media requires frequent, high-throughput access for active editing during the first 30 days after ingestion.
2. Archival Compliance Phase: After 30 days, assets must be kept for 7 years for regulatory compliance, during which time access is expected less than once per year only during legal discovery audits.

The Cloud Engineer must minimize Total Cost of Ownership (TCO) by eliminating unnecessary retrieval fees and avoiding minimum storage duration penalties.

Which TWO cloud storage bucket configuration and lifecycle management choices should the engineer recommend?

  1. Set the initial bucket default storage class to Standard storage, and apply an Object Lifecycle Management rule to transition objects to Archive storage after 30 days.Answer
  2. Ensure that archived video assets remain untouched in Archive storage for a minimum of 365 consecutive days before any deletion or overwrite operation.Answer
  3. C
    Set the default bucket storage class to Coldline storage starting from day 1 to reduce baseline storage costs during the active editing window.
  4. D
    Configure an Object Lifecycle Management policy to transition objects from Standard to Nearline storage on day 10, and then from Nearline to Archive storage on day 30.

Answer

The optimal strategy is to store newly ingested files in Standard storage and use an Object Lifecycle Management rule to transition them to Archive storage after 30 days, while ensuring objects remain in Archive storage for at least 365 days to avoid early deletion fees.
For frequently modified or read data in the first 30 days, Standard storage avoids retrieval fees. Transitioning to Archive storage after 30 days aligns with long-term retention needs (7 years) for data accessed less than once per year. Furthermore, keeping objects in Archive storage for at least 365 days satisfies its minimum storage duration policy, preventing early deletion charges.

Step-by-Step Solution

1
Analyze access frequency during the initial 30-day editing period
Standard storage is required during the first 30 days because frequent reads incur no data retrieval fees, preventing high operational costs.
Coldline, Nearline, and Archive classes assess data retrieval fees per gigabyte, making them cost-prohibitive for high-frequency access patterns.
2
Select the long-term retention class for data accessed less than once a year
Archive storage offers the lowest per-gigabyte monthly storage pricing for compliance assets rarely accessed.
Because the files are kept for 7 years and accessed fewer than once per year, Archive storage provides maximum cost savings despite higher retrieval costs upon access.
3
Evaluate minimum storage duration constraints for lifecycle transitions and deletions
Archive storage has a 365-day minimum storage duration requirement.
Deleting, overwriting, or re-tiering objects before 365 days results in pro-rated early deletion charges.
