Question 52 of 100 | ← Chapter 2

A developer wants to use AWS Elastic Beanstalk to test a new application version in a test environment. Which deployment strategy is the fastest?

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

Correct Answer: D. All at once

Explanation

The fastest deployment method is Option D: All at once. Explanation: All at once deployment: This method deploys the new version to all instances simultaneously. It is the fastest because it updates all instances in a single step, minimizing deployment time. However, it may result in temporary application unavailability while all instances are updated. Immutable deployment: Creates a new set of instances for the new version and switches traffic after testing. Though it enables zero-downtime deployments, it generally takes longer than All at once. Rolling deployment: Gradually deploys the new version across batches of instances, ensuring availability during each phase. While more robust, it takes longer than All at once. Rolling with additional batches: A hybrid approach deploying to subsets of instances sequentially. It balances speed and safety but is still slower than All at once. Therefore, for rapid testing of a new version in a test environment, All at once (Option D) is the most appropriate choice. 【Lantern Certification provided by: swufelp1999】
