Zorluk: OrtaBackup and Restore Management

An organization is setting up cross-Region replication for an Amazon S3 bucket named corp-data-primary to a destination bucket named corp-data-backup in another AWS Region. The SysOps Administrator has created the replication rule and assigned an IAM role with the necessary permissions. However, the replication status indicates that objects are not copying to the destination bucket. Which of the following configuration changes are required to successfully enable replication? (Select TWO.)

  1. Enable bucket versioning on the source S3 bucket.Cevap
  2. Enable bucket versioning on the destination S3 bucket.Cevap
  3. C
    Create an Amazon Route 53 CNAME record at the zone apex pointing to the destination bucket.
  4. D
    Modify the destination bucket's lifecycle policy to transition objects to Glacier Instant Retrieval.
  5. E
    Enable Multi-AZ deployment on the source bucket to initiate automated failover replication.

Cevap

Enable bucket versioning on both the source S3 bucket and the destination S3 bucket.
For Amazon S3 replication to work, versioning must be explicitly enabled on both the source bucket and the destination bucket. Without versioning enabled on both ends, S3 cannot track and replicate object versions.

Adım Adım Çözüm

1
Verify that bucket versioning is enabled on the source S3 bucket.
Enabling versioning on the source bucket allows Amazon S3 to track object versions, which is a requirement for replication.
Replication relies on versioning to uniquely identify and copy specific versions of objects.
2
Verify that bucket versioning is enabled on the destination S3 bucket.
Enabling versioning on the destination bucket ensures that the copied versions can be stored correctly.
Both the source and destination buckets must have versioning enabled for replication to succeed.

Anahtar Kavram

Amazon S3 cross-Region replication requires versioning to be enabled on both the source and destination buckets.
