Actual exam question for Amazon's CLF-C01 exam

Question #: 70
Topic #: 5

A company is running a critical workload on an Amazon RDS D8 instance. The company needs the DB instance to be highly available with a recovery time of less than 5 minutes. Which solution will meet these requirements?

ACreate a read replica of the DB instance.

BCreate a template of the DB instance by using AWS Cloud Formation.

CTake frequent snapshots of the DB instance. Store the snapshots in Amazon S3.

DModify the DB instance to be a Multi-AZ deployment.

Show Suggested Answer

Suggested Answer: D

A Multi-AZ deployment of Amazon RDS automatically provisions and maintains a synchronous standby replica in a different availability zone (AZ) than the primary instance. In the event of a failure of the primary instance, the replica is promoted to be the new primary instance, and the recovery time is less than 5 minutes. This ensures high availability for the critical workload and meets the company's requirement for a recovery time of less than 5 minutes. Additionally, it also provides automatic failover and data replication, so in case of any disaster or unplanned outage you will have a fully-working DB instance up and running with minimal data loss.
