SAP-C02 Continuous Improvement for Existing Solutions Practice Question
A company migrated a monolithic application to a microservices architecture on Amazon ECS. They notice that the CPU utilization of the cluster is high, but individual services are underutilized. What is the best optimization?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Right-size the task definitions by adjusting CPU and memory reservations.
Right-sizing the task definitions by adjusting CPU and memory reservations ensures each service receives the appropriate resources, reducing wasted capacity and optimizing cluster utilization. This directly addresses the high cluster CPU utilization while individual services are underutilized. Option A (increasing tasks) would exacerbate the issue. Option B (Fargate Spot) does not solve the resource allocation problem. Option C (EC2 launch type) is not relevant to the utilization pattern described.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the number of tasks for each service.
Why it's wrong here
Increasing tasks would increase CPU usage, not optimize it.
- ✗
Use AWS Fargate Spot for interruptible workloads.
Why it's wrong here
Fargate Spot reduces cost but does not address high cluster CPU utilization.
- ✗
Switch from Fargate to EC2 launch type.
Why it's wrong here
EC2 launch type does not inherently improve utilization.
- ✓
Right-size the task definitions by adjusting CPU and memory reservations.
Why this is correct
Proper sizing reduces over-provisioning and improves cluster utilization.
