SAA-C03 · Question #405
An ecommerce company runs a PostgreSQL database on an Amazon EC2 instance. The database stores data in Amazon Elastic Block Store (Amazon EBS) volumes. The daily peak input/output transactions per sec
The correct answer is C. Configure General Purpose SSD (gp3) EBS volumes. Provision 15,000 IOPS.. EBS gp3 volumes allow you to independently configure IOPS and throughput, up to 16,000 IOPS, regardless of the volume size, and at a lower cost compared to io1/io2 provisioned IOPS volumes. This meets the requirement for cost-effective, predictable IOPS performance for Amazon RDS
Question
An ecommerce company runs a PostgreSQL database on an Amazon EC2 instance. The database stores data in Amazon Elastic Block Store (Amazon EBS) volumes. The daily peak input/output transactions per second (IOPS) do not exceed 15,000 IOPS. The company wants to migrate the database to Amazon RDS for PostgreSQL and to provision disk IOPS performance that is independent of disk storage capacity. Which solution will meet these requirements MOST cost-effectively?
Options
- AConfigure General Purpose SSD (gp2) EBS volumes. Provision a 5 TiB volume.
- BConfigure Provisioned IOPS SSD (io1) EBS volumes. Provision 15,000 IOPS.
- CConfigure General Purpose SSD (gp3) EBS volumes. Provision 15,000 IOPS.
- DConfigure magnetic EBS volumes to achieve maximum IOPS.

Explanation
EBS gp3 volumes allow you to independently configure IOPS and throughput, up to 16,000 IOPS, regardless of the volume size, and at a lower cost compared to io1/io2 provisioned IOPS volumes. This meets the requirement for cost-effective, predictable IOPS performance for Amazon RDS for PostgreSQL.
