AWS Certified Solutions Architect Associate SAA-C03 Practice Question
An online retailer is experiencing slow website loading times for users accessing the site from different parts of the world. The website is hosted in EC2 instances behind a load balancer in a single region. The company wants to improve the website performance globally without making significant changes to their existing architecture. What is the most effective solution to reduce latency for international users?
Use a global network accelerator to route traffic to the load balancer.
Enable cross-region replication for storage buckets to store content in multiple regions.
Increase the number of virtual servers to handle more traffic.
Implement a content delivery network (CDN) with AWS CloudFront to cache static content closer to users.
Implementing a Content Delivery Network (CDN) such as Amazon CloudFront will cache the website static content at edge locations around the world, bringing the content closer to users and reducing latency. This approach does not require major changes to the existing infrastructure and is cost-effective. Increasing the number of servers would handle more traffic but does not address latency caused by geographical distance. Using a global network accelerator optimizes network routing but it does not provide the same level of content caching as CloudFront. Global Accelerator is more suitable for applications where you have multi-region architectures and need to route traffic to the best-performing region based on health checks. Enabling cross-region replication for storage buckets helps with data redundancy but does not directly improve website loading times for users accessing from different regions.
