SAA-C03 Question 256
Select 4An organization operates a global e-commerce platform and wants to deliver low-latency content to its users around the world. They also want to ensure compute services can dynamically scale close to the end users to handle localized workloads. Which combination of AWS services and infrastructure features should the organization use to achieve this?
- A
Amazon CloudFront with edge locations
- B
AWS Global Accelerator
- C
AWS Outposts
- D
AWS Lambda@Edge
- E
Amazon Route 53 Geolocation Routing
- F
Amazon EC2 Auto Scaling in a single AWS Region
Show answer and explanation
Correct answers: A, B, D, E
Explanation
To address global latency and scalability challenges, organizations should leverage AWS global infrastructure and edge services. Amazon CloudFront and AWS Global Accelerator optimize content delivery and traffic routing, while AWS Lambda@Edge enables compute at the edge for dynamic workloads. Amazon Route 53 Geolocation Routing helps direct users to the closest resources. These services collectively ensure low latency and high performance for a global application. AWS Outposts and EC2 Auto Scaling in a single Region are not designed for global distribution or edge computing.
- A. Correct.
Amazon CloudFront uses a network of globally distributed edge locations to cache and deliver content with low latency, making it an essential service for improving user experience for global platforms.
- B. Correct.
AWS Global Accelerator improves the availability and performance of applications by routing traffic to optimal endpoints using the AWS global network, reducing latency for global users.
- C. Incorrect.
AWS Outposts is a fully managed service that extends AWS infrastructure to on-premises environments. While useful for hybrid workloads, it does not help with global edge computing or latency reduction.
- D. Correct.
AWS Lambda@Edge allows you to run serverless functions at AWS edge locations, enabling you to execute logic closer to end users and reduce latency for dynamic content.
- E. Correct.
Amazon Route 53 Geolocation Routing directs traffic based on the location of users, which is helpful in directing users to the closest Region or endpoint, reducing latency.
- F. Incorrect.
Amazon EC2 Auto Scaling in a single AWS Region only scales compute capacity within that Region, which does not address global latency challenges for distributed users.
