AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A payment processing microservice runs on a single m5.large EC2 instance that uses a 500-GB gp2 volume for its MySQL data. During sales events, CloudWatch shows queue depth >10, latency >20 ms, and burst-balance near 0. The team must restore performance within minutes, avoid downtime, and keep storage costs low. Which action meets these requirements?

  • Use Elastic Volumes to modify the existing volume from gp2 to gp3 and, if required, provision 3,000 IOPS and 125 MiB/s throughput.

  • Enable EBS optimization on the instance to increase the bandwidth available to the current gp2 volume.

  • Create a new io2 volume with 3,000 provisioned IOPS, stop the instance, migrate the data, then attach the new volume.

  • Add two more 500-GB gp2 volumes, stripe them in RAID 0, and migrate the database to the new array.
