QuestionQ182

Managing and provisioning a cloud solution infrastructure

For this question, use the TerramEarth case study. TerramEarth has chosen to store data files in Cloud Storage. You need to configure a Cloud Storage lifecycle rule to retain 1 year of data while minimizing file storage cost.

Which two actions should you take?

  • A Create a Cloud Storage lifecycle rule with Age: ג€30ג€, Storage Class: ג€Standardג€, and Action: ג€Set to Coldlineג€, and create a second GCS life-cycle rule with Age: ג€365ג€, Storage Class: ג€Coldlineג€, and Action: ג€Deleteג€.
  • B Create a Cloud Storage lifecycle rule with Age: ג€30ג€, Storage Class: ג€Coldlineג€, and Action: ג€Set to Nearlineג€, and create a second GCS life-cycle rule with Age: ג€91ג€, Storage Class: ג€Coldlineג€, and Action: ג€Set to Nearlineג€.
  • C Create a Cloud Storage lifecycle rule with Age: ג€90ג€, Storage Class: ג€Standardג€, and Action: ג€Set to Nearlineג€, and create a second GCS life-cycle rule with Age: ג€91ג€, Storage Class: ג€Nearlineג€, and Action: ג€Set to Coldlineג€.
  • D Create a Cloud Storage lifecycle rule with Age: ג€30ג€, Storage Class: ג€Standardג€, and Action: ג€Set to Coldlineג€, and create a second GCS life-cycle rule with Age: ג€365ג€, Storage Class: ג€Nearlineג€, and Action: ג€Deleteג€.
Explanation

Cloud Storage lifecycle management can change Standard objects to Coldline storage, and it can delete objects when they meet an age and storage-class condition. Moving objects to Coldline at 30 days minimizes ongoing storage cost; deleting Coldline objects at 365 days retains them for one year and exceeds Coldline's 90-day minimum storage duration.
