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?

A. EBS bandwidth of dedicated instance exceeding the PIOPS

B. EBS volume size

C. EC2 bandwidth

D. Instance type is not EBS optimized








 

Suggested Answer: B

Community Answer: B

If the user is not experiencing the expected IOPS or throughput that is provisioned, ensure that the EC2 bandwidth is not the limiting factor, the instance is EBS- optimized (or include 10 Gigabit network connectivity) and the instance type EBS dedicated bandwidth exceeds the IOPS more than he has provisioned.
