• Chose A1

  Option A creates a completely separate environment with the newer Node.js version, deploys the new code there, and allows for testing without affecting the production environment. Once verified, you simply swap the URLs

• Chose C1

  A) Eliminated - This solution meets the requirement of zero downtime but may have additional resource and cost overhead. B) Eliminated - All-at-once deployment means that all instances are updated at the same time, which would result in downtime during the deployment. C) Correct - Immutable updates ensure that new EC2 instances are created, and only healthy instances will serve traffic. The old EC2 instances are not affected until the new instances are confirmed to be healthy and live. D) Eliminated - Rolling deployments help ensure that some EC2 instances are always running the old code and serving traffic while others are being updated.

  Option A is Correct not C: By cloning the production environment to a different platform version, you create a separate environment where you can safely deploy and test the new application code and platform version without affecting the live production environment.• Option C (Immutable update): While immutable updates ensure zero downtime by deploying to new instances, they do not address the need to update the Elastic Beanstalk platform version. Additionally, this approach can be more resource-intensive and costly.
