How to approach this question
Identify the native Cloud Storage feature for automating data retention and transition, and select the rules that match the timeframes.
Full Answer
Action: SetStorageClass to Coldline, Condition: Age = 30 days, Action: Delete, Condition: Age = 365 days
Cloud Storage Object Lifecycle Management allows you to define automated rules. To meet the requirements, you need two separate rules. Rule 1: Action = `SetStorageClass` (Coldline), Condition = `Age` (30 days). Rule 2: Action = `Delete`, Condition = `Age` (365 days). The `Age` condition measures the time since the object was created.
Common mistakes
Confusing the `Age` condition (duration) with the `CreatedBefore` condition (specific date).
