What is a valid difference between AWS Global Accelerator and Amazon CloudFront? Choose TWO responses.
A. AWS Global Accelerator uses the Anycast techniques to accelerate latency-sensitive applications Amazon CloudFront uses Unicast.
B. Amazon CloudFront makes use of Edge Locations and edge infrastructure, whilst AWS Global Accelerator does not.
C. AWS Global Accelerator does not include the content caching capability that Amazon CloudFront does.
D. AWS Global Accelerator is suitable for applications that are non-HTTP/S such as VoIP, MTTQ and gaming whereas Amazon CloudFront enhances the performance of HTTP-based content such as dynamic web applications, images and videos.
E. For the resource endpoint, Amazon CloudFront offers static public IP addresses whilst AWS Global Accelerator does not.
Correct Answer: C, D
AWS Global Accelerator uses the highly available, high-speed AWS global network and anycast routing techniques to greatly improve the availability and network performance of the customer application. By leveraging Edge Locations and edge infrastructure traffic to and from customer application endpoints ingresses and egresses the AWS global network at geographically closer locations to clients. Amazon CloudFront is a content delivery network (CDN) that improves the performance of cacheable web content, like videos, images, using content caches at Edge Locations.

- Option A is INCORRECT because Amazon CloudFront does not use Unicast techniques. Instead, it uses a content caching mechanism in delivering enhanced web application performance.
- Option B is INCORRECT because both AWS Global Accelerator and Amazon CloudFront service make use of Edge Locations and edge infrastructure on the AWS Global network.
- Option E is INCORRECT because Global Accelerator provides static public IP addresses for the customer resource endpoints, whilst the fully-qualified domain name of the Amazon CloudFront distribution can resolve to dynamic public IP addresses.
