AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

Your company stores application configuration files in a single Amazon S3 bucket. Developers occasionally overwrite files by mistake. Management requires the ability to restore any previous version for up to 90 days while keeping storage costs as low as possible. The solution must rely only on native AWS features and require no custom code. Which action meets these requirements?

  • Configure cross-region replication and disable replication of delete markers so older copies remain in the destination bucket for 90 days.

  • Enable bucket versioning and add a lifecycle rule that transitions noncurrent versions to S3 Glacier Instant Retrieval after 1 day and permanently deletes them after 90 days.

  • Enable object lock in compliance mode with a 90-day retention period on the bucket.

  • Enable bucket versioning and turn on MFA Delete to protect objects from accidental deletion.
