Difficulty: EasyBackup and Restore Management

A SysOps administrator needs to configure a backup and disaster recovery solution for an application. The application stores static assets in an Amazon S3 bucket and uses an Amazon RDS DB instance. The strategy requires that S3 objects be replicated to another AWS Region, and RDS backups must support point-in-time recovery and automated high availability. Which TWO actions should the SysOps administrator take to meet these requirements?

  1. Enable versioning on both the source and destination Amazon S3 buckets, and configure S3 Cross-Region Replication (CRR).Answer
  2. Enable automated backups on the Amazon RDS DB instance and configure a Multi-AZ deployment.Answer
  3. C
    Configure Amazon S3 Cross-Region Replication (CRR) on the source bucket without enabling versioning on either bucket.
  4. D
    Configure an RDS Read Replica in another Availability Zone and rely on it as the primary automated failover and backup mechanism.
  5. E
    Create an S3 Gateway Endpoint to copy the backups but do not associate it with the subnet route tables.

Answer

The correct actions are enabling versioning on both the source and destination Amazon S3 buckets and configuring S3 Cross-Region Replication, along with enabling automated backups on the RDS DB instance and configuring a Multi-AZ deployment.
To satisfy the backup and disaster recovery requirements, versioning must be enabled on both source and destination S3 buckets before setting up Cross-Region Replication. Additionally, enabling automated backups on the RDS DB instance enables point-in-time recovery, while configuring a Multi-AZ deployment ensures automated failover and high availability.

Step-by-Step Solution

1
Enable versioning on both the source and destination S3 buckets.
Both buckets are now version-controlled, which is a technical prerequisite for replication.
S3 Cross-Region Replication requires versioning to track and replicate object states accurately.
2
Configure S3 Cross-Region Replication (CRR) from the source bucket to the destination bucket.
Objects uploaded to the source bucket are automatically replicated to the destination bucket in the other Region.
This satisfies the requirement to replicate static assets to another AWS Region for disaster recovery.
3
Enable automated backups and configure Multi-AZ on the RDS DB instance.
The database has daily automated backups and transaction logs enabled for point-in-time recovery, plus a synchronous standby replica in another Availability Zone.
This satisfies the requirement for RDS backups supporting point-in-time recovery and automated high availability.
