The user has provisioned the PIOPS volume with an EBS optimized instance. Generally speaking, in which I/O chunk should the bandwidth experienced by the user be measured by AWS?
Suggested Answer:B🗳️
IOPS are input/output operations per second. Amazon EBS measures each I/O operation per second (that is 256 KB or smaller) as one IOPS. Reference: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-io-characteristics.html
B = 256kb for ssd and 1024 for hdd. would be nice if they specify type.

It should be B . (PIOPS is determined on ssd based storage with standard of 256KB of IO chunk)
ref : https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-io-characteristics.html
Not specific. According to the following doc,I /O size is capped at 256 KiB for SSD volumes and 1,024 KiB for HDD volumes
