An application serves dynamic, personalized content to users globally. The content cannot be cached. Users in Asia report high latency when accessing the application hosted in us-east-1. How can the architect improve network performance for these users?
Answer options:
A.
Use Amazon CloudFront with caching disabled.
B.
Use AWS Global Accelerator to route traffic over the AWS global network to the ALB in us-east-1.
C.
Deploy read replicas in Asia.
D.
Use Route 53 Latency-based routing.
How to approach this question
Identify the service designed to accelerate dynamic, non-cacheable traffic.
Full Answer
B.Use AWS Global Accelerator to route traffic over the AWS global network to the ALB in us-east-1.✓ Correct
Use AWS Global Accelerator to route traffic over the AWS global network to the ALB in us-east-1.
AWS Global Accelerator improves performance for dynamic applications by routing traffic over the AWS global network instead of the public internet, reducing packet loss and latency.
Common mistakes
Choosing CloudFront for strictly non-cacheable, dynamic traffic (though CloudFront can do dynamic routing, GA is purpose-built for this).
