- A
Use the Elastic Beanstalk console to deploy the previous application version.
Use the Elastic Beanstalk console or CLI to deploy a previous application version directly; this is the fastest method as it does not require additional environments or recreating resources.
- B
Swap environment URLs with a different environment that runs the previous version.
Why wrong: Swapping URLs with a different environment is not guaranteed to be faster because it requires another environment to exist and DNS propagation takes time; also, it may not be set up.
- C
Terminate the environment and create a new one with the previous version.
Why wrong: Terminating and recreating the environment is the slowest option, as it involves waiting for resources to be destroyed and re-provisioned, and it loses custom environment configurations.
- D
Redeploy the same application version to the environment.
Why wrong: Redeploying the same application version does not roll back; it simply reapplies the same problematic version, so it will not resolve the issue.
DOP-C02 Elastic Beanstalk rollback Practice Question
This DOP-C02 practice question tests your understanding of incident and event response. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: elastic Beanstalk rollback. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses AWS Elastic Beanstalk for its web application. After a deployment, the environment health changes to 'Severe' and the application becomes unresponsive. The DevOps team needs to quickly revert to the previous working version. What is the FASTEST way to achieve this?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use the Elastic Beanstalk console to deploy the previous application version.
Option A is correct because Elastic Beanstalk supports rolling back to a previous application version through the console or CLI, which is the fastest way to revert. Option B is wrong because swapping URLs requires an existing environment already running the previous version, and setting that up is slower. Option C is wrong because terminating and recreating the environment takes longer and loses configuration and data. Option D is wrong because redeploying the same version does not change anything and won't fix the issue.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Candidates may think swapping URLs is fastest, but it requires a second environment to exist and DNS propagation, making it slower than a direct version rollback.
Detailed technical explanation
How to think about this question
Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.
KKey Concepts to Remember

TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
