Topic 1 Question 394
A company is running a multi-tier ecommerce web application in the AWS Cloud. The application runs on Amazon EC2 instances with an Amazon RDS for MySQL Multi-AZ DB instance. Amazon RDS is configured with the latest generation DB instance with 2,000 GB of storage in a General Purpose SSD (gp3) Amazon Elastic Block Store (Amazon EBS) volume. The database performance affects the application during periods of high demand.
A database administrator analyzes the logs in Amazon CloudWatch Logs and discovers that the application performance always degrades when the number of read and write IOPS is higher than 20,000.
What should a solutions architect do to improve the application performance?
Replace the volume with a magnetic volume.
Increase the number of IOPS on the gp3 volume.
Replace the volume with a Provisioned IOPS SSD (io2) volume.
Replace the 2,000 GB gp3 volume with two 1,000 GB gp3 volumes.

- 正解だと思う選択肢: D
A - Magnetic Max IOPS 200 - Wrong B - gp3 Max IOPS 16000 per volume - Wrong C - RDS not supported io2 - Wrong D - Correct; 2 gp3 volume with 16 000 each 2*16000 = 32 000 IOPS

It can not be option C as RDS does not support io2 storage type (only io1). Here is a link to the RDS storage documentation: https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Storage.html Also it is not the best option to take Magnetic storage as it supports max 1000 IOPS. I vote for option B as gp3 storage type supports up to 64 000 IOPS where question mentioned with problem at level of 20 000.
