Exam question from Amazon's AWS Certified SysOps Administrator - Associate

Question #: 476
Topic #: 1

[All AWS Certified SysOps Administrator - Associate Questions]

A company runs a single-page web application on AWS. The application uses Amazon CloudFront to deliver static content from an Amazon S3 bucket origin. The application also uses an Amazon Elastic Kubernetes Service (Amazon EKS) cluster to serve API calls.

Users sometimes report that the website is not operational, even when monitoring shows that the index page is reachable and that the EKS cluster is healthy. A SysOps administrator must implement additional monitoring that can detect when the website is not operational before users report the problem.

Which solution will meet these requirements?

A. Create an Amazon CloudWatch Synthetics heartbeat monitor canary that points to the fully qualified domain name (FQDN) of the website.
B. Create an Amazon CloudWatch Synthetics API canary that monitors the availability of API endpoints from the EKS cluster.
C. Create an Amazon CloudWatch RUM app monitor that points to the fully qualified domain name (FQDN) of the website. Configure the app monitor to collect performance telemetry and JavaScript errors.
D. Create an Amazon CloudWatch RUM app monitor that uses the API endpoints from the EKS cluster.

Selected Answer: A

I would say better is A. It checks end to end, not only API calls.

Answer is B and chatGPT agrees: Answer is B and chatGPT agrees: to detect when the website is not operational before users report the problem, the SysOps administrator should implement synthetic monitoring. Create a CloudWatch Synthetics Canary: Amazon CloudWatch Synthetics allows you to create canaries, which are scripts that run on a scheduled basis to simulate user interactions with the web application. The canaries can check if both the index page (served from S3) and API endpoints (served from EKS) are reachable and functioning as expected.

it is A>>Amazon CloudWatch Synthetics allows you to create canaries to monitor your endpoints and APIs. A heartbeat monitor canary is like a scheduled task that automatically performs health checks at specified intervals. By creating a canary that points to the FQDN of the website, you can test the entire front-end application stack, including content delivery through Amazon CloudFront and the static content hosting on Amazon S3. While monitoring the API endpoints is important for ensuring that the application's backend is functioning correctly, it does not provide a complete picture of the user experience. Since the reported issue is that the website is not operational, it suggests that the problem may not be with the backend alone but could include the front end and the interaction between the front end and the backend.
