SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a critical application to AWS. The application requires consistent performance and low latency. The company has selected an instance type that meets the performance requirements. However, during testing, the application experiences variable performance due to CPU stealing from other instances on the same physical host. What should the company do to mitigate this issue?
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
✓
Use Amazon EC2 Dedicated Hosts for the instances
Dedicated Hosts provide dedicated physical servers, eliminating CPU stealing. Option B (placement group) helps with network performance, not CPU isolation. Option C (T2/T3 unlimited) is for burstable instances, not dedicated. Option D (C5 instance) does not prevent CPU stealing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use Amazon EC2 Dedicated Hosts for the instances
Why this is correct
Dedicated Hosts provide physical isolation, eliminating CPU stealing.
- ✗
Launch instances in a cluster placement group
Why it's wrong here
Cluster placement groups improve network performance, not CPU isolation.
- ✗
Use T2 or T3 instances with the unlimited credit option
Why it's wrong here
Unlimited credits affect bursting, not CPU stealing from other instances.
- ✗
Switch to a compute-optimized instance type such as C5
Why it's wrong here
Changing instance type does not prevent CPU stealing; physical host is still shared.
