Selected Answer: CD

Rolling with additional batch – Deploy the new version in batches, but first launch a new batch of instances to ensure full capacity during the deployment process. Immutable – Deploy the new version to a fresh group of instances by performing an immutable update." https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.rolling-version-deploy.html#environments-cfg-rollingdeployments-console

BD is the correct answer as the application must remain at the same level of server capacity throughout the deployment. Rolling with Additional Batch: Splits the deployments into batches but for the first batch creates new EC2 instances instead of deploying on the existing EC2 instances. Hence C is wrong

The catch is :Additionally, the application must remain at the same level of server capacity throughout the deployment" ..rolling with additional batch will increase the server capacity at some point before deleting the extras after the final deployment

However, using rolling will decrease the server capacity :/ Using rolling with additional batches can maintain same server capacity if you specify the correct batch size ;)

The problem states "no application downtime". In rolling, there will be downtime because there is not additional instance provisioned during the deployment. The correct answer is immutable and rolling with batches.

Furthermore with this statement "the application must remain at the same level of server capacity throughout the deployment", rolling will reduce the server capacity because one or more instances will be out of service because of the upgrade.
