Answer: Use cross-Region Read Replicas, Enable the automated backup feature of Amazon RDS in a multi-AZ deployment that creates backups in a single AWS Region
Use cross-Region Read Replicas In addition to using Read Replicas to reduce the load on your source DB instance, you can also use Read Replicas to implement a DR solution for your production DB environment. If the source DB instance fails, you can promote your Read Replica to a standalone source server. Read Replicas can also be created in a different Region than the source database. Using a cross-Region Read Replica can help ensure that you get back up and running if you experience a regional availability issue. Enable the automated backup feature of Amazon RDS in a multi-AZ deployment that creates backups in a single AWS Region Amazon RDS provides high availability and failover support for DB instances using Multi-AZ deployments. Amazon RDS uses several different technologies to provide failover support. Multi-AZ deployments for MariaDB, MySQL, Oracle, and PostgreSQL DB instances use Amazon's failover technology. The automated backup feature of Amazon RDS enables point-in-time recovery for your database instance. Amazon RDS will backup your database and transaction logs and store both for a user-specified retention period. If it’s a Multi-AZ configuration, backups occur on the standby to reduce I/O impact on the primary. Automated backups are limited to a single AWS Region while manual snapshots and Read Replicas are supported across multiple Regions. Incorrect options: Enable the automated backup feature of Amazon RDS in a multi-AZ deployment that creates backups across multiple Regions - This is an incorrect statement. Automated backups are limited to a single AWS Region while manual snapshots and Read Replicas are supported across multiple Regions. Use RDS Provisioned IOPS (SSD) Storage in place of General Purpose (SSD) Storage - Amazon RDS Provisioned IOPS Storage is an SSD-backed storage option designed to deliver fast, predictable, and consistent I/O performance. This storage type enhances the performance of the RDS database, but this isn't a disaster recovery option. Use database cloning feature of the RDS DB cluster - This option has been added as a distractor. Database cloning is only available for Aurora and not for RDS.
