CLF-C02 Cloud Technology and Services Practice Question
A company wants to deploy a static website with global low-latency delivery and automatic SSL/TLS certificates. Which combination of AWS services best satisfies both requirements?
⚠ Common exam trap
Many exam-takers think AWS Amplify (Option C) is a valid combination of services, but Amplify is a single managed service. The question explicitly asks for a 'combination' of services. While Amplify does provide automatic SSL/TLS certificates and global low-latency delivery via its underlying CloudFront integration, it is not a combination of separate services like S3 and CloudFront. Thus, the correct answer is the combination of S3 and CloudFront.

Correct answer & explanation
✓
Amazon S3 + Amazon CloudFront
Amazon S3 provides durable, cost-effective storage for static website content, while Amazon CloudFront acts as a global content delivery network (CDN) that caches content at edge locations for low-latency delivery. CloudFront also integrates with AWS Certificate Manager (ACM) to automatically provision and renew SSL/TLS certificates at no additional cost, enabling HTTPS without manual certificate management.
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 EC2 + Elastic Load Balancing
Why it's wrong here
Running a static website on Amazon EC2 with Elastic Load Balancing is inefficient because you must manage and patch the underlying instances, configure scaling policies, and ensure high availability across Availability Zones. Additionally, ELB only distributes traffic to regional instances and does not provide global edge caching, so users in remote locations experience higher latency compared to content delivered from CloudFront's worldwide point-of-presence cache.
- ✓
Amazon S3 + Amazon CloudFront
Why this is correct
Amazon S3 + Amazon CloudFront is the best fit for a static website with global reach. S3 stores the HTML/CSS/JS and media files, while CloudFront caches that content at 400+ edge locations, drastically reducing latency for global users. You also get built-in HTTPS through AWS Certificate Manager and can further restrict S3 bucket access to only CloudFront using an origin access control (OAC), making the solution both secure and fully managed with no servers to maintain.
- ✗
AWS Amplify only
Why it's wrong here
AWS Amplify can host static websites and automatically provides a global CDN, but it wraps S3, CloudFront, and CodeCommit into a higher-level service focused on CI/CD pipelines. Choosing 'Amplify only' hides the underlying architecture rather than demonstrating the specific storage plus CDN combination that the question asks about. It also locks you into Amplify's build/deploy workflow, whereas S3 + CloudFront gives you direct control over caching and origin settings—making Amplify a valid but less precise answer for this fundamental architecture.
- ✗
Amazon Lightsail + Route 53
Why it's wrong here
Amazon Lightsail + Route 53 is not appropriate because Lightsail provides virtual private servers (VPS) with fixed CPU/RAM/disk, so you still handle OS maintenance and there is no built-in global CDN; it primarily offers regional DNS-based load balancing within a VPC. Route 53 only handles DNS resolution and failover, not caching or content acceleration. Together they do not give you the edge caching and automatic scaling needed for low-latency distribution to a worldwide audience, unlike S3 + CloudFront.

AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
