A Developer Is Updating an Application Deployed on AWS Elastic

Multiple Choice

A developer is updating an application deployed on AWS Elastic Beanstalk. The new version is incompatible with the old version.

How can this be performed with the LEAST amount of downtime?

A) Use the Elastic Beanstalk All at once deployment policy to update all instances simultaneously.
B) Perform an Elastic Beanstalk Rolling with additional batch deployment.
C) Deploy the new version in a new Elastic Beanstalk environment and swap environment URLs.
D) Perform an Elastic Beanstalk Rolling deployment.
