AWS Certified Solutions Architect – Professional — Question 44

A user has configured EBS volume with PIOPS. The user is not experiencing the optimal throughput.
Which of the following could not be factor affecting I/O performance of that EBS volume?

Answer options

• A. EBS bandwidth of dedicated instance exceeding the PIOPS
• B. EBS volume size
• C. EC2 bandwidth
• D. Instance type is not EBS optimized

Correct answer: B

Explanation

The EBS volume size does not influence I/O performance when using PIOPS, as performance is determined by the provisioned IOPS and other factors. In contrast, EBS bandwidth, EC2 bandwidth, and whether the instance type is EBS optimized can all significantly impact the throughput experienced.
