Q4 — AWS DVA-C02 Ch.2
Question 4 of 100 | ← Chapter 2
A developer wants to test a new version of an application in a test environment using AWS Elastic Beanstalk. Which deployment policy results in the fastest deployment?
- A. Immutable
- B. Rolling
- C. Rolling with additional batch
- D. All at once ✓
Correct Answer: D. All at once
Explanation
Option D (All at once) is the fastest deployment strategy. In an 'All at once' deployment, all instances in the environment are updated simultaneously, making the new application version available almost immediately. While this may cause brief downtime during the update, it is the quickest method for testing new versions. In contrast, Immutable, Rolling, and Rolling with additional batch strategies update instances incrementally, resulting in longer overall deployment durations—especially undesirable when speed is prioritized for testing.
