AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

The gp3 volume type decouples capacity from performance and is priced about 20 % lower than gp2 while offering a default 3 000 IOPS that can be provisioned up to 16 000 IOPS and 1 000 MiB/s. Using the Elastic Volumes feature, the team can modify the existing gp2 volume to gp3 and set higher IOPS and throughput online, so no instance stop, snapshot, or re-attach is required. Migrating to io2 or io2 Block Express would also reduce latency, but those volumes are significantly more expensive and therefore do not satisfy the cost constraint. Purchasing burst credits for gp2 is not possible; the volume automatically earns credits based on size. Converting to st1 lowers costs but is optimized for large sequential throughput and would increase latency for random OLTP workloads.
