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

Yes B is correct. Explanation: Set up a Route 53 active-passive failover configuration. Direct traffic to a static error page hosted within an Amazon S3 bucket when Route 53 health checks determine that the ALB endpoint is unhealthy. The Solutions Architect can have both the primary website and the backup static error page in a single S3 bucket. All the Solutions Architect needs to do is set up a Route 53 active-passive failover configuration which will direct the traffic to the static error page when Route 53 health check detects that the ALB endpoint is unhealthy. This configuration meets the company's needs while minimizing changes and infrastructure overhead.

Aggree with B, this design help for failover and key "minimal changes"

If you have failover, then what is the point informing the user of failure instead of redirecting to a working copy? Also, how many times would you display the error message? Failover is to provide the service

yes, you are correct. Not sure how A/P will help for static error pages.

Are you telling me that I shouldn’t spend money on that course? Cos that’s the wrong answer https://aws.amazon.com/premiumsupport/knowledge-center/fail-over-s3-r53/

I agree with Neal's answer as A because the failover takes effects immediately, not depending on DNS cache expiry on client side. A adds one more service (CloudFront), and so does B (adds S3). With A, we don't need set up failover health check as we must do with B.

I agree that in Neal Davis Practice exam, its answer is A, but almost people always choose B, that maybe comes from the states "minimizing changes and infrastructure", B option is easier to implement than A. If you chose A, you would do more things, such as creating an ALB, config it to EC2 instances, then create CF and config it to ALB, create an error page and config CF to this error page, finally config Route53 to CF. I'm not sure the cost in option A is more expensive than B or not
