AWS Certified Solutions Architect – Professional — Question 521

A user is creating a Provisioned IOPS volume. What is the maximum ratio the user should configure between Provisioned IOPS and the volume size?

Answer options

• A. 30 to 1
• B. 50 to 1
• C. 10 to 1
• D. 20 to 1

Correct answer: B

Explanation

For Amazon EBS Provisioned IOPS SSD (io1) volumes, the maximum ratio of provisioned IOPS to the volume size in GiB is 50 to 1. This allows users to provision up to 50 IOPS per GiB of storage. Other ratios like 10:1, 20:1, and 30:1 are valid but do not represent the maximum allowable limit.
