An EBS-backed EC2 instance's IOPS is bottlenecked. Which is the appropriate scaling response WITHOUT changing the instance type?
AMove all data to Amazon Glacier Deep Archive
BReduce the EBS volume size to half
CDisable EBS encryption
DSwitch the EBS volume to io2 / io2 Block Express and provision the needed IOPS independently of volume size
Answer & Solution
Correct answer: D. Switch the EBS volume to io2 / io2 Block Express and provision the needed IOPS independently of volume size
Provisioned-IOPS SSD (io2/io2 BX) lets IOPS scale independently of capacity. Glacier is archival, halving size hurts more, disabling encryption is unrelated and a regression.
