CLF-C02 Question 213
Single answerYou are designing an application that requires low-latency access for global users and needs to cache frequently accessed content at edge locations. Which AWS service should you use to meet this requirement?
- A
Amazon CloudFront
- B
AWS Global Accelerator
- C
AWS Direct Connect
- D
Amazon S3
Show answer and explanation
Correct answer: A
Explanation
Amazon CloudFront is the correct choice because it is specifically designed to deliver content with low latency and high transfer speeds by caching it at AWS edge locations worldwide. While AWS Global Accelerator and AWS Direct Connect are designed for improving network performance and connectivity, they do not provide caching functionality. Amazon S3 is a storage service and does not include content delivery features.
- A. Correct.
Amazon CloudFront is a content delivery network (CDN) service that securely delivers data, videos, applications, and APIs to users globally with low latency by caching content at edge locations.
- B. Incorrect.
AWS Global Accelerator improves availability and performance for a wide range of applications by routing traffic through the AWS global network but does not provide content caching at edge locations.
- C. Incorrect.
AWS Direct Connect provides a dedicated network connection between your on-premises environment and AWS, but it does not involve edge locations or caching.
- D. Incorrect.
Amazon S3 is an object storage service that provides scalable storage for data but does not deliver cached content at edge locations.
