- A
Use Amazon Lightsail containers to deploy each microservice as a container service.
Why wrong: Lightsail is for simpler workloads; not designed for complex microservices with auto scaling.
- B
Deploy each microservice on separate EC2 instances behind an Application Load Balancer.
Why wrong: EC2 instances are not containerized; managing containers on EC2 adds overhead.
- C
Use Amazon ECS with Fargate to run each microservice as a separate task definition, with service auto scaling.
ECS with Fargate is a fully managed container service that decouples services and scales independently.
- D
Use AWS Elastic Beanstalk with Docker platform to deploy each microservice as a separate environment.
Why wrong: Elastic Beanstalk abstracts containers but may not be ideal for many microservices (environment limits).
Quick Answer
The correct answer is to use Amazon ECS with Fargate, running each microservice as a separate task definition with service auto scaling. This solution directly addresses the need for decoupled, independently scalable services by leveraging Fargate’s serverless compute engine, which eliminates the overhead of managing EC2 instances while providing native Docker container orchestration. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your understanding of choosing the right container orchestration model for microservices at scale—specifically, the trade-off between control (ECS with EC2) and operational simplicity (Fargate). A common trap is selecting Elastic Beanstalk, which abstracts containers but lacks the fine-grained service isolation and auto scaling granularity that ECS task definitions provide. Remember the memory tip: “Fargate for Frictionless scaling, separate tasks for decoupled services.”
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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 wants to deploy a new web application on AWS that uses a microservices architecture. The company expects rapid growth and wants to decouple services to allow independent scaling and development. The team wants to use Docker containers for consistency across environments. Which solution should a Solutions Architect recommend?
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 ECS with Fargate to run each microservice as a separate task definition, with service auto scaling.
Option D is correct because ECS with Fargate is a managed container service that scales automatically and decouples services. Option A is wrong because EC2 instances are not containerized. Option B is wrong because Elastic Beanstalk is a PaaS that abstracts containers but may not provide as much control. Option C is wrong because Lightsail is for simpler workloads, not microservices at scale.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
