Question #1362
Which AWS service employs a global network of edge locations to cache and distribute content for reduced latency?
Amazon Elastic Compute Cloud (Amazon EC2)
Amazon DynamoDB
Amazon CloudFront
AWS Config
Explanation
Amazon CloudFront (C) is designed to accelerate content delivery using a global network of edge locations. When content is requested, CloudFront caches copies at edge locations closest to users, reducing latency by serving content from the nearest cache. This makes it ideal for distributing static and dynamic web content, videos, and APIs.
Other options are incorrect because:
- A. Amazon EC2: A compute service for virtual servers, region-specific and not focused on caching or global distribution.
- B. Amazon DynamoDB: A managed NoSQL database service; while it offers global tables for cross-region replication, it does not use edge locations for caching.
- D. AWS Config: A service for tracking resource configuration changes, unrelated to content delivery.
Key Points: CloudFront's edge locations are critical for low-latency content delivery, distinguishing it from compute, database, or monitoring services.
Answer
The correct answer is: C
