Exam AWS Certified SysOps Administrator - Associate topic 1 question 157 discussion

Exam question from Amazon's AWS Certified SysOps Administrator - Associate
Question #: 157
Topic #: 1
[All AWS Certified SysOps Administrator - Associate Questions]

A company has an existing web application that runs on two Amazon EC2 instances behind an Application Load Balancer (ALB) across two Availability Zones. The application uses an Amazon RDS Multi-AZ DB Instance. Amazon Route 53 record sets route requests for dynamic content to the load balancer and requests for static content to an Amazon S3 bucket. Site visitors are reporting extremely long loading times.

Which actions should be taken to improve the performance of the website? (Choose two.)

  • A. Add Amazon CloudFront caching for static content.
  • B. Change the load balancer listener from HTTPS to TCP.
  • C. Enable Amazon Route 53 latency-based routing.
  • D. Implement Amazon EC2 Auto Scaling for the web servers.
  • E. Move the static content from Amazon S3 to the web servers.

AD: A is obvious D If servers are working to total capacity the ASG will help to increase the performance, If is a latency issue C will not work because both are in the same region

A D /// C is wrong as it mentioned that ( (ALB) across two Availability Zones ) JUST 1 region !!! what is the point in C, Route 53 latency routing if it all goes to one region anyway ?

Add Amazon CloudFront caching for static content. Implement Amazon EC2 Auto Scaling for the web servers. Not Enable Amazon Route 53 latency-based routing.: “To use latency-based routing, you create latency records for your resources in multiple AWS Regions.” https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-policy-latency.html

True A. Add Amazon CloudFront caching for static content. (For S3) Wrong B. Change the load balancer listener from HTTPS to TCP. (ALB not supported TCP. NLB supported TCP and has extreme perfermance) Wrong C. Enable Amazon Route 53 latency-based routing. (Application is in one region. Dont need latency) True D. Implement Amazon EC2 Auto Scaling for the web servers. (Auto Scailing can control app perfermance by scale out and scale in) Wrong E. Move the static content from Amazon S3 to the web servers.

ans: AC A. Add Amazon CloudFront caching for static content. -YES B. Change the load balancer listener from HTTPS to TCP. - doesn't make any sense C. Enable Amazon Route 53 latency-based routing. - YES D. Implement Amazon EC2 Auto Scaling for the web servers. - This won't help with loading E. Move the static content from Amazon S3 to the web servers. - no, cloudfront caching going to solve this problem
