Question
A company is running a critical workload on an Amazon RDS DB 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?a.Create a read replica of the DB instance.b.Create a template of the DB instance by using AWS CloudFormation.c.Modify the DB instance to be a Multi-AZ deployment.d.Take frequent snapshots of the DB instance. Store the snapshots in Amazon S3.
Solution
The solution that will meet these requirements is c. Modify the DB instance to be a Multi-AZ deployment.
Here's why:
a. Creating a read replica of the DB instance would not meet the requirement for high availability and recovery time of less than 5 minutes. Read replicas are primarily used for offloading read traffic from the primary DB instance, not for high availability.
