問題 #309
A company has a website that is developed in PHP and is launched using AWS Elastic Beanstalk. There is a new version of the website that needs to be deployed in the Elastic Beanstalk environment. The company cannot tolerate having the website offline if an update fails. Deployments must have minimal impact and rollback as soon as possible.

• A. Rolling
• B. Immutable
• C. All at once
• D. Snapshots

答案：B

解題說明：
The Immutable deployment method is the best choice when a company requires minimal downtime and automatic rollback in case of a failure. Here's why:
* In Immutable deployments, a new set of instances is launched with the updated version. These instances are tested and validated before they replace the old instances. This ensures zero downtime and immediate rollback if the deployment fails.
* All at once (A) causes downtime because the update replaces all instances simultaneously.
* Rolling deployments (B) update a few instances at a time, but if a failure occurs midway, downtime or partial unavailability can happen.
* Snapshots (C) are not a deployment strategy in Elastic Beanstalk.
