AWS Certified SysOps Administrator – Associate (legacy) — Question 438

In Amazon RDS, which of the following provides enhanced availability and durability for Database (DB) Instances, making them to be a natural fit for production database workloads?

Answer options

• A. Placement Groups
• B. Multi-Option Group deployment
• C. Multi-AZ deployment
• D. Multi-VPC deployment

Correct answer: C

Explanation

Amazon RDS Multi-AZ deployments automatically provision and maintain a synchronous standby replica in a different Availability Zone, ensuring high availability and automatic failover for production workloads. Placement Groups are used for EC2 instance network performance rather than RDS durability, while Option Groups manage database engine features and do not provide high availability.
