Answer: Distribute load across multiple resources

Edge locations are part of Amazon CloudFront's content delivery network (CDN) infrastructure. Their primary functions include: - **Distribute content to users**: Edge locations serve cached content to end users from locations closer to them - **Cache common responses**: They store frequently accessed content to reduce latency - **Used in conjunction with the CloudFront service**: Edge locations work with CloudFront to deliver content efficiently However, **distributing load across multiple resources** is NOT a feature of edge locations. Load distribution is handled by services like Elastic Load Balancing (ELB), not by edge locations. Edge locations focus on content caching and delivery rather than load balancing across backend resources.
