Zorluk: KolayAmazon S3 Storage Class and Lifecycle Optimization

A company stores daily database backups in an Amazon S3 Standard bucket. A SysOps administrator is creating an Amazon S3 Lifecycle configuration to transition these backups to S3 Standard-Infrequent Access (S3 Standard-IA) to reduce storage costs. What is the minimum number of days the backups must remain in S3 Standard before they can be transitioned to S3 Standard-IA?

  1. A
    15 days
  2. B
    0 days
  3. 30 daysCevap
  4. D
    90 days

Cevap

The backups must remain in S3 Standard for a minimum of 30 days before transitioning to S3 Standard-IA.
The correct answer is 30 days because Amazon S3 enforces a minimum constraint of 30 days before objects in S3 Standard can be transitioned to S3 Standard-IA or S3 One Zone-IA.

Adım Adım Çözüm

1
Identify the target storage class for the lifecycle transition, which is S3 Standard-IA.
The target storage class is S3 Standard-IA.
S3 Lifecycle transition rules differ depending on the destination storage class.
2
Recall the Amazon S3 Lifecycle transition constraints for S3 Standard-IA.
Objects must be stored in S3 Standard for at least 30 days before transitioning to S3 Standard-IA.
This is a hard constraint enforced by the Amazon S3 service for cost-effective lifecycle transitions.
3
Select the option that represents this minimum constraint.
The minimum duration is 30 days.
Values lower than 30 days will cause a policy validation failure, while values higher than 30 days are not the minimum.

Anahtar Kavram

S3 Lifecycle transition constraints specify that objects must reside in S3 Standard for a minimum of 30 days before transitioning to S3 Standard-IA or S3 One Zone-IA.
