Question 840
An architecture review recommends this solution: Select an appropriate EBS gp3 volume with independently provisioned performance settings and test application throughput. The motivating situation is: An EC2 application needs sustained random IOPS independent of EBS volume storage-size growth. What principle supports the selected implementation?
Explanation
Correct Answer
This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Select an appropriate EBS gp3 volume with independently provisioned performance settings and test application throughput. The expected supporting evidence is: The volume reaches measured IOPS requirements without unnecessary capacity inflation.
Incorrect Answers
Capacity planning ignores demand spikes or hot keys that concentrate requests. The stated evidence instead indicates: Gp2 capacity-linked performance assumptions lead to wasteful storage growth.
Misses from different edge caches repeatedly burden the same origin. The stated evidence instead indicates: Gp2 capacity-linked performance assumptions lead to wasteful storage growth.
Health checks use an unrelated always-200 endpoint that does not reflect the service readiness. The stated evidence instead indicates: Gp2 capacity-linked performance assumptions lead to wasteful storage growth.
