AWS Certified Solutions Architect Associate SAA-C03 Practice Question
A multinational organization is experiencing latency issues with their online platform, which delivers frequently updated dynamic content. The platform operates from the North American East Coast and the user experience is degrading for clients in various international locations. Which service should be leveraged to enhance the platform's responsiveness for customers worldwide?
Utilize Amazon Route 53 to manage global DNS queries and automatically route users based on proximity.
Configure AWS Global Accelerator to directly improve the dynamic content delivery to clients.
Establish AWS Direct Connect links from the origin server locations to each international region.
Implement Amazon CloudFront for caching and distributing the dynamic content to global edge locations.
Amazon CloudFront is a global content delivery network (CDN) that can both cache static objects and accelerate non-cacheable dynamic HTTP(S) traffic by terminating connections at edge locations and carrying requests over the AWS private backbone. This places data closer to end users and greatly reduces latency for a single-region web workload.
AWS Global Accelerator also lowers latency for dynamic TCP/UDP traffic by routing it over the AWS backbone and providing anycast IP addresses, but it does not cache objects. It is typically selected when you need fixed IPs, multi-region fail-over, or support for non-HTTP protocols; therefore it is not the best fit when edge caching is required.
Amazon Route 53 can respond with the lowest-latency Region, yet it neither accelerates traffic nor caches content. AWS Direct Connect provides dedicated private network connectivity between on-premises networks and AWS and does not improve last-mile internet latency for end users.
Because the organization needs global edge caching and HTTP(S) acceleration to mitigate end-user latency, Amazon CloudFront is the most appropriate choice.
