CLF-C02 Cloud Technology and Services Practice Question
A company hosts a static website on Amazon S3. Users in different geographic locations experience high latency when accessing the website. The company wants to reduce latency for all users and also minimize the number of direct requests to the S3 bucket. Which AWS service should the company use?
⚠ Common exam trap
Many exam-takers confuse AWS Global Accelerator (which optimizes network path but does not cache) with CloudFront (which caches content at the edge), leading them to choose Global Accelerator for a static website latency problem.
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, significantly reducing latency for users regardless of their geographic location. By serving content from the edge, CloudFront also offloads direct requests to the S3 bucket, reducing the load on the origin and potentially lowering costs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Global Accelerator
Why it's wrong here
AWS Global Accelerator improves the performance of TCP and UDP applications by directing traffic over the AWS global network, but it does not cache content. It still forwards requests to the origin, so it would not reduce the number of direct requests to the S3 bucket or provide the same latency reduction as a CDN.
When this WOULD be correct
A company has a dynamic web application or an API that requires fast and reliable TCP/UDP traffic routing, and they need to improve performance for users globally while also providing static IP addresses for whitelisting. In that scenario, AWS Global Accelerator would be the correct choice.
- ✓
Amazon CloudFront
Why this is correct
Amazon CloudFront is a content delivery network (CDN) that caches static content at edge locations worldwide. This reduces latency by serving content from a nearby edge location and reduces the number of direct requests to the S3 bucket, thereby offloading the origin.
- ✗
Amazon Route 53 latency-based routing
Why it's wrong here
Amazon Route 53 latency-based routing directs users to the AWS endpoint with the lowest latency (e.g., an S3 bucket in a specific region). However, each request still goes to the S3 bucket, and the user may still experience latency due to the distance from the bucket. It does not cache content.
When this WOULD be correct
Route 53 latency-based routing would be correct if the company hosts dynamic content on multiple EC2 instances across regions and wants to route users to the region with the lowest latency, without needing caching or reducing direct requests to the origin.
- ✗
AWS Direct Connect
Why it's wrong here
AWS Direct Connect provides a dedicated private network connection from an on-premises data center to AWS. It does not improve latency for global users accessing the website over the public internet, nor does it reduce requests to the S3 bucket.
When this WOULD be correct
A company needs a dedicated, private, and consistent network connection between its on-premises data center and AWS to reduce latency, increase bandwidth, or meet compliance requirements for hybrid cloud workloads.
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 content delivery network (CDN) that caches static content at edge locations worldwide. This reduces latency by serving content from a nearby edge location and reduces the number of direct requests to the S3 bucket, thereby offloading the origin.
✗AWS Global AcceleratorWrong answer — click to see why▾
Why this is wrong here
AWS Global Accelerator improves performance for TCP/UDP traffic by routing over the AWS global network, but it does not cache static content or reduce direct requests to the S3 bucket. For a static website, CloudFront's content delivery network (CDN) is the appropriate service to cache content at edge locations and minimize S3 requests.
★ When this WOULD be the correct answer
A company has a dynamic web application or an API that requires fast and reliable TCP/UDP traffic routing, and they need to improve performance for users globally while also providing static IP addresses for whitelisting. In that scenario, AWS Global Accelerator would be the correct choice.
Why candidates choose this
Candidates may confuse Global Accelerator's global network optimization with CloudFront's caching capabilities, assuming both reduce latency similarly, but Global Accelerator does not cache content.
✗Amazon Route 53 latency-based routingWrong answer — click to see why▾
Why this is wrong here
Amazon Route 53 latency-based routing directs traffic to the region with the lowest latency, but it does not cache content or reduce direct requests to the S3 bucket; each user request still goes directly to S3, which can cause high latency and load on the bucket.
★ When this WOULD be the correct answer
Route 53 latency-based routing would be correct if the company hosts dynamic content on multiple EC2 instances across regions and wants to route users to the region with the lowest latency, without needing caching or reducing direct requests to the origin.
Why candidates choose this
Candidates may think that routing based on latency directly reduces user latency, but they overlook that it doesn't cache content or offload requests from the origin, which is necessary for static content served from a single S3 bucket.
✗AWS Direct ConnectWrong answer — click to see why▾
Why this is wrong here
AWS Direct Connect establishes a dedicated network connection from on-premises to AWS, which does not reduce latency for geographically distributed users accessing a public S3 website, nor does it minimize direct S3 requests.
★ When this WOULD be the correct answer
A company needs a dedicated, private, and consistent network connection between its on-premises data center and AWS to reduce latency, increase bandwidth, or meet compliance requirements for hybrid cloud workloads.
Why candidates choose this
Candidates may think Direct Connect can improve latency by providing a faster path to AWS, but it only benefits traffic from a specific on-premises location, not global users.
