- A
Use Elastic Load Balancer, Amazon EC2 instances for the web tier, and Amazon ECS with Fargate for the application tier, and Amazon RDS for MySQL.
Why wrong: Using EC2 for the web tier still requires managing instances, not fully serverless.
- B
Use Application Load Balancer, Amazon ECS with Fargate for both web and application tiers, and Amazon Aurora MySQL.
Fargate eliminates server management, and Aurora provides managed MySQL with high availability.
- C
Use Amazon CloudFront, Amazon EC2 instances for the application tier, and Amazon DynamoDB.
Why wrong: EC2 for application tier adds overhead, and DynamoDB is not MySQL-compatible.
- D
Use Amazon EC2 Auto Scaling groups for both web and application tiers, and Amazon RDS for MySQL with Multi-AZ.
Why wrong: EC2 instances require manual patching and scaling management, increasing operational overhead.
SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
This SAP-C02 practice question tests your understanding of accelerate workload migration and modernization. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is planning to migrate a large-scale e-commerce platform from on-premises to AWS. The platform includes a web tier, application tier, and a MySQL database. The company needs to ensure high availability and scalability. Which combination of AWS services should the company use to modernize the application architecture while minimizing operational overhead?
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 Application Load Balancer, Amazon ECS with Fargate for both web and application tiers, and Amazon Aurora MySQL.
Option B is correct because it uses a managed container service (ECS with Fargate) for both web and application tiers, eliminating server management overhead, and Amazon Aurora MySQL provides a MySQL-compatible, highly available, and scalable managed database. Option A is incorrect because although it includes a load balancer and ECS with Fargate for the application tier, it uses unmanaged EC2 instances for the web tier, increasing operational overhead. Option C is incorrect because it proposes DynamoDB, which is NoSQL and not suitable for a MySQL-based e-commerce platform. Option D is incorrect because it uses EC2 instances for both tiers, requiring more manual management compared to a containerized solution.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
