AWS Certified SysOps Administrator – Associate (legacy) — Question 162

A user is trying to create a PIOPS EBS volume with 4000 IOPS and 100 GB size. AWS does not allow the user to create this volume. What is the possible root cause for this?

Answer options

• A. The ratio between IOPS and the EBS volume is higher than 30
• B. The maximum IOPS supported by EBS is 3000
• C. The ratio between IOPS and the EBS volume is lower than 50
• D. PIOPS is supported for EBS higher than 500 GB size

Correct answer: A

Explanation

The correct answer is A because the limit for IOPS per GB for PIOPS volumes is 30, and a 100 GB volume can only support a maximum of 3000 IOPS. Therefore, trying to provision 4000 IOPS for a 100 GB volume exceeds this ratio. Options B, C, and D do not accurately address the IOPS to volume size ratio issue.
