AWS Certified Developer – Associate (DVA-C02) — Question 124

A developer wants to use AWS Elastic Beanstalk to test a new version of an application in a test environment.

Which deployment method offers the FASTEST deployment?

Answer options

• A. Immutable
• B. Rolling
• C. Rolling with additional batch
• D. All at once

Correct answer: D

Explanation

The 'All at once' deployment method is the fastest because it updates all instances simultaneously, minimizing downtime. In contrast, the other methods, like Immutable and Rolling, involve phased updates, which take longer to complete as they ensure stability and minimize risk during the deployment process.
