Difficulty: MediumPlanning Cloud Storage Buckets and Storage Classes

A media production company ingests raw high-definition footage into Google Cloud Storage for daily video editing. Editors frequently read and modify the video files during the first 30 days after ingestion. Between day 31 and day 365, the footage is accessed infrequently (typically once per quarter) for producing retrospective highlight reels, but must remain available immediately with millisecond latency when requested. After 365 days, the footage is no longer required and should be permanently removed. Which Cloud Storage lifecycle configuration minimizes total costs while satisfying these operational access requirements?

  1. Create a bucket with the default storage class set to Standard. Configure an Object Lifecycle Management rule to transition objects to Coldline storage after 30 days, and a second rule to delete objects after 365 days.Answer
  2. B
    Create a bucket with the default storage class set to Coldline. Configure an Object Lifecycle Management rule to transition objects to Archive storage after 30 days, and a second rule to delete objects after 365 days.
  3. C
    Create a bucket with the default storage class set to Standard. Configure an Object Lifecycle Management rule to transition objects to Archive storage after 30 days, and a second rule to delete objects after 365 days.
  4. D
    Create a bucket with the default storage class set to Nearline. Configure an Object Lifecycle Management rule to transition objects to Coldline storage after 30 days, and a second rule to delete objects after 365 days.

Answer

Create a bucket with the default storage class set to Standard. Configure an Object Lifecycle Management rule to transition objects to Coldline storage after 30 days, and a second rule to delete objects after 365 days.
Starting with Standard storage ensures zero retrieval charges during the intensive 30-day editing period. Coldline storage ideal for quarterly access patterns (once every 90 days), offering low storage costs while maintaining immediate millisecond access latency. Deleting after 365 days automates resource cleanup.

Step-by-Step Solution

1
Analyze initial data access frequency
Files are accessed frequently for 30 days, requiring Standard storage class to avoid data retrieval charges.
Nearline, Coldline, and Archive classes charge retrieval fees per gigabyte, making them expensive for frequently accessed active workloads.
2
Evaluate secondary access frequency and SLAs
Files accessed once per quarter after 30 days fit Coldline storage parameters.
Coldline storage is optimized for data accessed at most once every 90 days (quarterly) while still providing immediate millisecond access without retrieval delays.
3
Define lifecycle retention limits
Configure a deletion rule for objects reaching 365 days of age.
Automating object deletion after 1 year prevents paying unnecessary ongoing storage fees for unneeded video rushes.
