• 正解だと思う選択肢: C

  Explanation: The rolling with additional batch deployment policy allows Elastic Beanstalk to launch additional instances in a new batch before terminating the old instances. In this case, specifying a batch size of 1 means that Elastic Beanstalk will deploy the application updates to 1 new instance at a time, ensuring that there are always at least 4 instances available during the deployment process. This method maintains application performance while minimizing the additional cost.

• The correct answer is: D. Change the deployment policy to rolling. Specify a batch size of 2.

  A rolling deployment policy will deploy the new application version to one batch of instances at a time, while the other batches continue to serve traffic. This ensures that the application always has at least four instances available during the deployment.

  Specifying a batch size of 2 means that two instances will be deployed at a time. This is the most cost-effective option because it minimizes the number of instances that are needed to maintain application performance during the deployment.

  The other options are not as cost-effective because they require more instances to be running during the deployment. Option A requires six instances, option B requires at least five instances, and option C requires at least four instances.
