The answer is to add the `elasticbeanstalk:CreateApplicationVersion` and `elasticbeanstalk:DeleteApplicationVersion` permissions to the CodePipeline service role. This is correct because the 403 error explicitly indicates that the pipeline’s IAM role lacks the authorization to call `CreateApplicationVersion`, which is a required API action when CodePipeline deploys a new application version to Elastic Beanstalk. The pipeline role must have permissions for both creating and cleaning up application versions, as the deploy stage needs to register the zip artifact before updating the environment. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of how CodePipeline interacts with Elastic Beanstalk through service roles, and a common trap is confusing the pipeline role with the Elastic Beanstalk service role—the pipeline role handles the API calls, not the environment’s role. A helpful memory tip is “Pipeline pushes, Beanstalk receives—the pipeline role needs create and delete sleeves.”
DOP-C02 SDLC Automation Practice Question
This DOP-C02 practice question tests your understanding of sdlc automation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 startup is using AWS CodePipeline to deploy a Python web application to AWS Elastic Beanstalk. The pipeline has a source stage (CodeCommit), a build stage (CodeBuild), and a deploy stage (Elastic Beanstalk). The build stage runs unit tests and creates a deployable zip file. The deploy stage uses the Elastic Beanstalk deploy provider. Recently, the deploy stage started failing with the error: 'The API call 'elasticbeanstalk:CreateApplicationVersion' failed with status 403.' The CodePipeline service role has the following permissions: 'elasticbeanstalk:DescribeApplications', 'elasticbeanstalk:DescribeEnvironments', 'elasticbeanstalk:UpdateEnvironment'. What should the DevOps engineer do to resolve the issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Add the 'elasticbeanstalk:CreateApplicationVersion' and 'elasticbeanstalk:DeleteApplicationVersion' permissions to the CodePipeline service role
Option A is correct because the error indicates the pipeline role lacks permission to create an application version, which is necessary for deployment. Adding elasticbeanstalk:CreateApplicationVersion and related actions will resolve the issue. Option B is wrong because the Elastic Beanstalk service role is for the environment, not the pipeline. Option C is wrong because the pipeline does not need S3 permissions for Elastic Beanstalk deployment. Option D is wrong because the error is about permissions, not environment configuration.
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.
✗
Change the deploy provider to use CodeDeploy instead of Elastic Beanstalk
Why it's wrong here
Changing the provider is not necessary; fixing permissions is simpler.
✗
Add 's3:PutObject' permission to the CodePipeline service role to allow it to upload the zip file to S3
Why it's wrong here
CodePipeline uses S3 implicitly, but the error is about CreateApplicationVersion.
✓
Add the 'elasticbeanstalk:CreateApplicationVersion' and 'elasticbeanstalk:DeleteApplicationVersion' permissions to the CodePipeline service role
Why this is correct
These permissions are required to create new application versions.

✗
Update the Elastic Beanstalk environment's service role to allow CodePipeline to deploy
Why it's wrong here
The environment role does not affect the pipeline's permissions.
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.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
