AWS Certified Solutions Architect – Professional — Question 45

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

Correct answer: D

Explanation

The correct answer is D because AWS requires that the ratio of IOPS to the size of the EBS volume must be between 3 and 30 for PIOPS. Since 4000 IOPS for a 100 GB volume results in a ratio of 40, which is above the allowed maximum of 30, this configuration is not permitted. Options A and B provide incorrect specifications regarding size and IOPS limits, while option C misstates the acceptable ratio range.
