SAP-C02 Design for New Solutions Practice Question
A startup wants to deploy a web application on AWS with a serverless architecture. The application includes static content (HTML, CSS, JS) and a REST API backend using Lambda and DynamoDB. The company wants low latency and high availability globally. Which combination of services should they use?
⚠ Common exam trap
Candidates often confuse Lambda@Edge as a full compute solution for APIs, overlooking its severe execution limits, or assume that an ALB provides global low latency when it is inherently regional and requires additional services like Global Accelerator for global performance.
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
✓
Amazon CloudFront for static content, Amazon API Gateway for the REST API, and AWS Lambda for compute.
It combines Amazon CloudFront for global low-latency delivery of static content, Amazon API Gateway to create and manage the REST API with built-in caching and throttling, and AWS Lambda for serverless compute. This architecture provides high availability, automatic scaling, and global edge caching, meeting the startup's requirements without managing servers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon CloudFront for static content, Application Load Balancer for API, and Lambda for compute.
Why it's wrong here
ALB is not serverless and adds cost.
- ✗
AWS Lambda@Edge for both static content and API.
Why it's wrong here
Lambda@Edge is for lightweight edge processing, not full API.
- ✓
Amazon CloudFront for static content, Amazon API Gateway for the REST API, and AWS Lambda for compute.
Why this is correct
CloudFront provides CDN, API Gateway manages APIs, Lambda runs code serverlessly.
- ✗
Amazon S3 for static content with Transfer Acceleration, and AWS Lambda for API.
Why it's wrong here
Transfer Acceleration is for uploads, not global distribution.
