- A
Amazon CloudFront
Amazon CloudFront is a global content delivery network (CDN) that caches static content at edge locations, reducing latency. It integrates with ACM for free SSL/TLS certificates, supports custom domain names, and enforces HTTPS. This meets all the requirements without any server management.
- B
AWS Global Accelerator
Why wrong: AWS Global Accelerator improves performance for TCP/UDP traffic by routing users to the nearest healthy endpoint using static IP addresses. However, it does not cache content; it simply optimizes the network path. It is not designed for serving static web content from edge locations, and it does not provide HTTPS termination with custom domain names by itself.
- C
Amazon S3 Transfer Acceleration
Why wrong: Amazon S3 Transfer Acceleration speeds up uploads to S3 buckets by using edge locations. It is not designed for downloading or serving content to end users. Since the company already has all content in S3 and wants to serve it globally, Transfer Acceleration does not address low-latency downloads or HTTPS enforcement with custom domains.
- D
AWS Lambda@Edge
Why wrong: Lambda@Edge allows you to run code at CloudFront edge locations in response to events. It is a compute service, not a content delivery service. While it can be used in conjunction with CloudFront, it alone cannot serve static content or manage HTTPS. The company needs a CDN, not just compute at the edge.
CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. 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 hosts its corporate website entirely as static content (HTML, CSS, JavaScript, images) in an Amazon S3 bucket. The website currently has no authentication requirements and is accessible to the public. The company wants to serve this content to users around the world with low latency. Additionally, the company wants to enforce HTTPS for all traffic using a custom domain name (www.example.com). The company does not want to manage SSL/TLS certificates on any servers. Which AWS service should the company use to meet these requirements?
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
Amazon CloudFront is a content delivery network (CDN) that caches static content at edge locations worldwide, reducing latency for global users. It supports custom domain names and can enforce HTTPS by using AWS Certificate Manager (ACM) to provision and renew SSL/TLS certificates automatically, eliminating the need for server-side certificate management. CloudFront integrates directly with an S3 bucket as the origin, allowing the bucket to remain private while serving content securely via HTTPS.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Amazon CloudFront
Why this is correct
Amazon CloudFront is a global content delivery network (CDN) that caches static content at edge locations, reducing latency. It integrates with ACM for free SSL/TLS certificates, supports custom domain names, and enforces HTTPS. This meets all the requirements without any server management.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
AWS Global Accelerator
Why it's wrong here
AWS Global Accelerator improves performance for TCP/UDP traffic by routing users to the nearest healthy endpoint using static IP addresses. However, it does not cache content; it simply optimizes the network path. It is not designed for serving static web content from edge locations, and it does not provide HTTPS termination with custom domain names by itself.
When this WOULD be correct
A company runs a multi-region application behind an Application Load Balancer and needs to improve global latency and provide a static IP address for whitelisting, while also using AWS Shield for DDoS protection. Global Accelerator would be the correct choice.
- ✗
Amazon S3 Transfer Acceleration
Why it's wrong here
Amazon S3 Transfer Acceleration speeds up uploads to S3 buckets by using edge locations. It is not designed for downloading or serving content to end users. Since the company already has all content in S3 and wants to serve it globally, Transfer Acceleration does not address low-latency downloads or HTTPS enforcement with custom domains.
When this WOULD be correct
A company needs to upload large files (e.g., videos, backups) to an S3 bucket from geographically distributed clients and wants to minimize upload latency. The question would specify that the requirement is about accelerating uploads, not serving content to users.
- ✗
AWS Lambda@Edge
Why it's wrong here
Lambda@Edge allows you to run code at CloudFront edge locations in response to events. It is a compute service, not a content delivery service. While it can be used in conjunction with CloudFront, it alone cannot serve static content or manage HTTPS. The company needs a CDN, not just compute at the edge.
When this WOULD be correct
A company uses CloudFront to deliver a web application and needs to modify HTTP headers or perform URL redirects based on user location or device type. Lambda@Edge would be the correct service to run such custom logic at edge locations without managing servers.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.
✓Amazon CloudFrontCorrect answer▾
Why this is correct
Amazon CloudFront is a global content delivery network (CDN) that caches static content at edge locations, reducing latency. It integrates with ACM for free SSL/TLS certificates, supports custom domain names, and enforces HTTPS. This meets all the requirements without any server management.
✗AWS Global AcceleratorWrong answer — click to see why▾
Why this is wrong here
AWS Global Accelerator improves availability and performance for TCP/UDP traffic but does not provide content caching at edge locations or enforce HTTPS with custom SSL certificates; it also cannot serve static content directly from S3 with low latency via caching.
★ When this WOULD be the correct answer
A company runs a multi-region application behind an Application Load Balancer and needs to improve global latency and provide a static IP address for whitelisting, while also using AWS Shield for DDoS protection. Global Accelerator would be the correct choice.
Why candidates choose this
Candidates may confuse Global Accelerator's edge location IP anycast for low-latency delivery with CloudFront's content caching and HTTPS termination capabilities, assuming both serve similar purposes for static content.
✗Amazon S3 Transfer AccelerationWrong answer — click to see why▾
Why this is wrong here
Amazon S3 Transfer Acceleration speeds up uploads to S3, not content delivery to end users. It does not provide HTTPS enforcement for custom domains or low-latency global distribution of static content.
★ When this WOULD be the correct answer
A company needs to upload large files (e.g., videos, backups) to an S3 bucket from geographically distributed clients and wants to minimize upload latency. The question would specify that the requirement is about accelerating uploads, not serving content to users.
Why candidates choose this
Candidates may confuse 'acceleration' with content delivery, assuming Transfer Acceleration can serve content faster globally, but it only optimizes the upload path to S3, not the download path to users.
✗AWS Lambda@EdgeWrong answer — click to see why▾
Why this is wrong here
Lambda@Edge is used to run custom code at CloudFront edge locations, but it does not serve static content or enforce HTTPS on its own. The question requires serving static content with low latency and HTTPS, which CloudFront provides natively without needing Lambda@Edge.
★ When this WOULD be the correct answer
A company uses CloudFront to deliver a web application and needs to modify HTTP headers or perform URL redirects based on user location or device type. Lambda@Edge would be the correct service to run such custom logic at edge locations without managing servers.
Why candidates choose this
Candidates may think Lambda@Edge can handle HTTPS termination or content delivery because it runs at edge locations, but it is an add-on for custom logic, not a primary content delivery or HTTPS solution.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse S3 Transfer Acceleration (which only accelerates uploads) with CloudFront (which accelerates downloads and caches content), or they think Global Accelerator can serve static content with HTTPS, but it lacks caching and certificate management at the edge.
Detailed technical explanation
How to think about this question
CloudFront uses a global network of edge locations to cache objects based on TTL headers, reducing origin load and latency. When configured with an S3 origin, CloudFront can be set to require HTTPS between viewers and CloudFront, and between CloudFront and S3, using Origin Access Control (OAC) to keep the bucket private. A real-world scenario where this matters is a global e-commerce site that needs fast, secure delivery of product images without managing certificates on multiple servers.
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.
Quick reference

| 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 |
