Difficulty: EasyBackup and Restore Management

A SysOps Administrator is configuring Amazon S3 Cross-Region Replication (CRR) to replicate backup archives from a source bucket in the us-east-1 Region to a destination bucket in the us-west-2 Region. Which actions are required to successfully enable this configuration? (Select TWO.)

  1. Enable versioning on the source S3 bucketAnswer
  2. Enable versioning on the destination S3 bucketAnswer
  3. C
    Enable RDS Multi-AZ failover on the source bucket to automate cross-Region failover
  4. D
    Configure an Amazon RDS Read Replica in the destination Region to synchronize the bucket contents
  5. E
    Configure the S3 Cross-Region Replication rules without enabling versioning on either bucket to minimize storage costs

Answer

Enabling versioning on both the source S3 bucket and the destination S3 bucket is required to configure Amazon S3 Cross-Region Replication.
To configure S3 Cross-Region Replication (CRR), Amazon S3 requires bucket versioning to be explicitly enabled on both the source bucket and the destination bucket. This allows S3 to preserve historical versions of the objects during replication and prevent accidental data loss.

Step-by-Step Solution

1
Identify the source and destination Amazon S3 buckets for Cross-Region Replication.
Source and destination buckets are selected in us-east-1 and us-west-2.
Replication requires a clearly defined source and destination.
2
Enable Bucket Versioning on the source S3 bucket.
Versioning is active on the source bucket.
Amazon S3 replication requires versioning to keep track of object versions.
3
Enable Bucket Versioning on the destination S3 bucket.
Versioning is active on the destination bucket.
The destination bucket must match the versioning state of the source bucket for replication to succeed.
