AWS Certified Data Engineer Associate DEA-C01 Practice Question
A company is migrating its 250 GiB on-premises MySQL OLTP database to Amazon RDS. Normal activity averages 200 IOPS, but during quarterly financial closes the workload spikes to 15,000 IOPS for several hours. The team wants to guarantee this peak performance at the lowest monthly storage cost. Which RDS storage configuration meets the requirements?
General Purpose SSD (gp2) and allocate about 5 TiB to reach 15,000 baseline IOPS.
General Purpose SSD (gp3) with at least 400 GiB of storage and 15,000 provisioned IOPS.
Provisioned IOPS SSD (io1) with 300 GiB of storage and 15,000 IOPS.
General Purpose SSD (gp3) with the existing 250 GiB volume and keep the default 3,000 IOPS.
General Purpose SSD (gp3) volumes let you provision IOPS independently of capacity, but extra IOPS can be added only when the volume is at least 400 GiB. By creating a 400 GiB (or larger) gp3 volume and provisioning 15,000 IOPS, the database can sustain the spike while paying gp3's lower per-GiB rate and inexpensive $0.005 per provisioned IOPS over the free 3,000 baseline.
gp2 delivers just 3 IOPS/GiB; achieving 15,000 baseline IOPS would need about 5 TiB, dramatically increasing cost.
A gp3 volume that keeps the default 3,000 IOPS can't satisfy the spike.
io1 can meet 15,000 IOPS, but its higher $0.125/GB plus $0.065 per IOPS makes it more expensive than gp3 for the same performance.
