- A
Amazon CloudFront for static content, Application Load Balancer for API, and Lambda for compute.
Why wrong: ALB is not serverless and adds cost.
- B
AWS Lambda@Edge for both static content and API.
Why wrong: Lambda@Edge is for lightweight edge processing, not full API.
- C
Amazon CloudFront for static content, Amazon API Gateway for the REST API, and AWS Lambda for compute.
CloudFront provides CDN, API Gateway manages APIs, Lambda runs code serverlessly.
- D
Amazon S3 for static content with Transfer Acceleration, and AWS Lambda for API.
Why wrong: Transfer Acceleration is for uploads, not global distribution.

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 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?
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.
Option C is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.

Read the scenario before looking for a memorised answer.
- ✗
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.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may 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.
Detailed technical explanation
How to think about this question
CloudFront integrates with API Gateway via edge-optimized API endpoints, which route requests through CloudFront's global edge locations to reduce latency. API Gateway can also cache responses at the edge, further improving performance for repeated requests. Lambda functions behind API Gateway scale horizontally based on request volume, and DynamoDB's auto-scaling handles throughput changes, ensuring high availability across multiple AWS regions if configured with global tables.
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.
TExam Day Tips
- 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.
