- A
Delete the environment and recreate it with the new AMI.
Why wrong: Deleting the environment causes downtime.
- B
Build a new AMI using a tool like Packer and store it in EC2 Image Builder.
Packer or Image Builder can create updated AMIs.
- C
Use Elastic Beanstalk's immutable update policy to replace instances with new ones.
Immutable updates ensure zero downtime.
- D
Update the Elastic Beanstalk environment configuration to use the new AMI ID.
Updating the configuration triggers a deployment.
- E
Terminate all existing instances and allow Auto Scaling to launch new ones with the new AMI.
Why wrong: This would cause downtime.
Question 1,124 of 1,750
Automate AMI Update in Elastic Beanstalk with Zero Downtime
This DOP-C02 practice question tests your understanding of configuration management and iac. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.
An organization uses AWS Elastic Beanstalk to manage a production web application. The application uses a custom AMI that needs to be updated periodically. The team wants to automate the process of updating the AMI and deploying it to the environment with zero downtime. Which THREE steps should the team include in the automation? (Choose THREE.)

Correct answer & explanation
✓
Build a new AMI using a tool like Packer and store it in EC2 Image Builder.
To automate AMI updates with zero downtime, the team should: (1) Build a new AMI using a tool like Packer and store it in EC2 Image Builder for versioning (Option B). (2) Update the Elastic Beanstalk environment configuration to reference the new AMI ID (Option D). (3) Use Elastic Beanstalk's immutable update policy, which creates new instances with the new AMI and then swaps them with old instances, ensuring zero downtime (Option C). Options A and E are incorrect because deleting/recreating the environment or terminating instances without a controlled deployment strategy would cause downtime. Immutable updates provide a safer mechanism.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
