The answer is that the environment is configured to use a launch template, and the AMI was not updated in the launch template. Elastic Beanstalk relies on either a launch configuration or a launch template to define instance properties; when a launch template is in use, updating the AMI in the environment’s configuration settings does not automatically propagate to the template, so new instances continue using the old AMI. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your understanding of how Elastic Beanstalk decouples environment configuration from the underlying compute resources—a common trap is assuming that changing the environment’s AMI setting alone is sufficient, when in fact you must explicitly edit the launch template’s AMI ID. Remember the tip: “Template trumps config”—if a launch template is attached, always check the template itself for the AMI, not the environment’s general settings.
SOA-C02 Deployment, Provisioning, and Automation Practice Question
This SOA-C02 practice question tests your understanding of deployment, provisioning, and automation. 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.
A company is using AWS Elastic Beanstalk to deploy a web application. The application uses a custom Amazon Machine Image (AMI) that must be updated periodically. The SysOps administrator creates a new AMI and updates the Elastic Beanstalk environment's configuration. However, new instances are still launched with the old AMI. What is the most likely cause?

Correct answer & explanation
✓
The environment is configured to use a launch template, and the AMI was not updated in the launch template.
Elastic Beanstalk uses a launch configuration or launch template. If the environment is configured to use a launch template, updating the AMI in the environment configuration may not update the template. The environment's platform version is separate from the AMI. The old AMI might not be deregistered, but that doesn't cause new instances to use it. Immutable updates are not relevant.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The environment is configured to use a launch template, and the AMI was not updated in the launch template.
Why this is correct
If using a launch template, the AMI must be updated in the template itself.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The environment is using an immutable update policy.
Why it's wrong here
Immutable updates replace instances but still use the configuration's AMI.
✗
The environment's platform version is pinned to an older version.
Why it's wrong here
Platform version is different from custom AMI.
✗
The old AMI was not deregistered.
Why it's wrong here
Deregistering does not affect instances already launched; the configuration still points to the old AMI.

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.
