- A
Use Amazon DynamoDB for game state, AWS Lambda for game logic, and API Gateway for client communication.
Why wrong: Lambda is not suitable for stateful game server logic; API Gateway adds latency.
- B
Use Amazon GameLift for session-based game server hosting, with its built-in matchmaking and fleet management.
GameLift is purpose-built for multiplayer games, handles scaling, matchmaking, and low-latency.
- C
Deploy game servers on EC2 instances behind a Network Load Balancer. Use ElastiCache for Redis for game state and SQS for chat messages.
Why wrong: EC2 instances require manual management of scaling and patching; not optimized for gaming.
- D
Use Amazon ECS with Fargate to run game server containers, and use Application Auto Scaling to handle load.
Why wrong: Fargate containers may have higher latency than required for real-time gaming; GameLift is more suitable.
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 gaming company is designing a new real-time multiplayer game backend on AWS. The game requires low-latency communication between players (< 50 ms) and the ability to handle up to 100,000 concurrent players. The backend must manage game state, player matchmaking, and chat. The company wants to use managed AWS services to reduce operational overhead. 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 GameLift for session-based game server hosting, with its built-in matchmaking and fleet management.
Option B is correct because Amazon GameLift is purpose-built for session-based multiplayer game hosting, providing integrated matchmaking, fleet management, and auto-scaling to handle up to 100,000 concurrent players with low latency. Option A is incorrect because although DynamoDB can store game state, AWS Lambda is not ideal for real-time game logic due to cold start latency and limited execution duration, and API Gateway adds latency overhead, making it unsuitable for sub-50 ms requirements. Option C is incorrect because deploying game servers on EC2 instances requires manual management of scaling, patching, and fleet health, increasing operational overhead, and while ElastiCache Redis can handle game state and SQS can handle chat, the overall solution lacks a managed game server hosting service. Option D is incorrect because Amazon ECS with Fargate abstracts infrastructure management but does not provide built-in session management, matchmaking, or low-latency optimization for gaming workloads, and containers may introduce latency overhead.
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
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
