Zorluk: OrtaAmazon S3 Storage Class and Lifecycle Optimization

An administrator is configuring an Amazon S3 Lifecycle policy for a bucket containing high-resolution LIDAR sensor data logs. The logs, which average 1.5 GB1.5\text{ GB} in size, are frequently accessed for the first 1515 days after upload. After 1515 days, they are rarely accessed but must remain available with millisecond retrieval times. The administrator creates a lifecycle rule to transition the objects to S3 Standard-Infrequent Access (S3 Standard-IA) 1515 days after creation, and then to S3 Glacier Deep Archive 9090 days after creation.

What will happen when the administrator attempts to apply this S3 Lifecycle policy?

  1. A
    The policy will be successfully applied, but Amazon S3 will delay the transition to S3 Standard-IA until 3030 days have elapsed from the object creation date.
  2. The configuration will fail validation and reject the policy because S3 Lifecycle rules require a minimum of 3030 days to elapse before transitioning objects to S3 Standard-IA.Cevap
  3. C
    The policy will fail validation because transitioning objects directly from S3 Standard-IA to S3 Glacier Deep Archive is not a supported transition path.
  4. D
    The policy will fail validation because objects transitioned to S3 Standard-IA must remain in that storage class for at least 3030 days before transitioning to S3 Glacier Deep Archive.

Cevap

The configuration will fail validation and reject the policy because S3 Lifecycle rules require a minimum of 3030 days to elapse before transitioning objects to S3 Standard-IA.
The correct option is correct because Amazon S3 Lifecycle rules enforce a validation constraint that prevents transitioning objects from S3 Standard to S3 Standard-IA (or S3 One Zone-IA) earlier than 3030 days after object creation. Since the policy specifies a transition to S3 Standard-IA after 1515 days, it violates this sequence restriction and will be rejected with a validation error upon application.

Adım Adım Çözüm

1
Check the minimum storage duration requirements for S3 Standard-IA transitions within S3 Lifecycle configurations.
Identify that S3 Lifecycle requires objects to spend a minimum of 3030 days in S3 Standard or S3 Intelligent-Tiering before they are eligible to transition to S3 Standard-IA or S3 One Zone-IA.
This establishes the validation baseline for the proposed 1515-day transition.
2
Compare the administrator's proposed lifecycle timeline against the S3 transition constraints.
The proposed timeline attempts to transition files to S3 Standard-IA at day 1515, which is less than the 3030-day minimum requirement.
This identifies the direct cause of the validation failure in the policy.
3
Verify downstream lifecycle transition rules.
The transition from S3 Standard-IA to S3 Glacier Deep Archive at day 9090 is valid, as it flows to a colder tier and exceeds the required minimum elapsed time.
This confirms that the primary transition rule at day 1515 is the sole blocker preventing successful policy validation.

Anahtar Kavram

S3 Lifecycle transition rules enforce strict timing validation constraints, including a mandatory minimum of 3030 days in a warmer tier before transitioning to S3 Standard-IA or S3 One Zone-IA. Configurations violating this constraint will fail API validation during deployment.
