Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 299 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C02
Question #: 299
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A company serves a multilingual website from a fleet of Amazon EC2 instances behind an Application Load Balancer (ALB). This architecture is currently running in the us-west-1 Region but is exhibiting high request latency for users located in other parts of the world.
The website needs to serve requests quickly and efficiently regardless of a user's location. However, the company does not want to recreate the existing architecture across multiple Regions.
How should a solutions architect accomplish this?

  • A. Replace the existing architecture with a website served from an Amazon S3 bucket. Configure an Amazon CloudFront distribution with the S3 bucket as the origin.
  • B. Configure an Amazon CloudFront distribution with the ALB as the origin. Set the cache behavior settings to only cache based on the Accept-Language request header.
  • C. Set up Amazon API Gateway with the ALB as an integration. Configure API Gateway to use an HTTP integration type. Set up an API Gateway stage to enable the API cache.
  • D. Launch an EC2 instance in each additional Region and configure NGINX to act as a cache server for that Region. Put all the instances plus the ALB behind an Amazon Route 53 record set with a geolocation routing policy.

B https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/header-caching.html Configuring caching based on the language of the viewer: If you want CloudFront to cache different versions of your objects based on the language specified in the request, configure CloudFront to forward the Accept-Language header to your origin.

Also we do not know if the website has dynamic content or not. Putting it in S3 means that we have assumed that the website is static.

B. https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/header-caching.html#header-caching-web-language: "If you want CloudFront to cache different versions of your objects based on the language specified in the request, configure CloudFront to forward the Accept-Language header to your origin." A is out because they did not say its a Static website. D is out because of the keyword 'does not want to duplicate the present infrastructure across numerous regions'

TIE BREAKER .. COMBO!!!! Answer is B. Caching is key along with NOT needing to restructure the current cloud architecture from instances to S3. The auto-scaling will work fine.

Also, the didn't say it's a static website to host on S3. That's why B is the answer.
