AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 48

An organization delivers high-resolution, dynamic web content. Internet users access the content from a variety of platforms, including mobile, tablet and desktop.
Each platform receives a customized experience to account for the differences in viewing modes. A dedicated, automatic-scaling fleet of Amazon EC2 instances is used for each platform to server content based on path-based headers.
Which combination of services will MINIMIZE cost and MAXIMIZE performance? (Choose two.)

Answer options

• A. Amazon CloudFront with Lambda@Edge
• B. Network Load Balancer
• C. Amazon S3 static websites
• D. Amazon Route 53 with traffic flow policies
• E. Application Load Balancer

Correct answer: A, E

Explanation

The correct answer is A and E because Amazon CloudFront with Lambda@Edge allows for efficient content delivery and customization at the edge, reducing latency and costs. Application Load Balancer is suitable for managing traffic based on content and provides features like path-based routing, which is ideal for delivering tailored experiences. The other options, while useful, do not optimize cost and performance as effectively as the selected services.
