AWS Certified Cloud Practitioner — Question 399
Which component of the AWS global infrastructure provides low-latency access to content in multiple geographic areas by storing copies of data close to end users?
Answer options
- A. AWS Regions
- B. Availability Zones
- C. Local Zones
- D. Edge locations
Correct answer: D
Explanation
Edge locations are used by services like Amazon CloudFront to cache copies of content closer to end users, significantly reducing latency. AWS Regions and Availability Zones are designed for hosting core infrastructure and services rather than global content caching. Local Zones place compute and storage services closer to specific metropolitan areas but are not the primary mechanism for global content delivery.
