Difficulty: EasyDesigning Infrastructure for Business Requirements and Cost Optimization

A financial services enterprise needs to archive historical transaction audit logs to Google Cloud for compliance. The logs are accessed very rarely (less than once per year) but must be retained for seven years. The primary business requirement is to minimize storage costs while automating data lifecycle governance. Which TWO actions should the team take to achieve these business and cost requirements? (Select TWO)

  1. Configure Cloud Storage Lifecycle Management rules to transition objects from Standard to Archive Storage class after 30 days of inactivity.Answer
  2. Use Cloud Storage Lifecycle Management to automatically delete noncurrent object versions after the mandatory seven-year retention period expires.Answer
  3. C
    Store the uncompressed historical log files in Cloud Spanner to allow SQL queries across all archived logs.
  4. D
    Provision a Dedicated Interconnect connection exclusively to transfer historical batch logs overnight.

Answer

Transitioning logs to Archive Storage via Object Lifecycle Management and automatically deleting expired object versions after the seven-year retention period minimize storage costs and eliminate manual management overhead.
Transitioning infrequently accessed objects to Archive Storage provides the lowest per-gigabyte storage cost, and configuring lifecycle rules to automatically remove objects past their 7-year retention period prevents paying for unnecessary storage after compliance obligations end.

Step-by-Step Solution

1
Analyze access frequency and retention requirements
Infrequent access (<1/year) points to the Archive Storage class as the most cost-effective tier.
Selecting the lowest cost storage class matching access frequency reduces unit cost per GB.
2
Evaluate lifecycle automation options
Automating storage tier transitions and final object deletions using Object Lifecycle Management prevents manual intervention and avoids storing expired data.
Automation enforces business compliance while preventing unexpected storage cost accumulation.
