The correct answer is to use AWS CodePipeline, AWS CodeBuild, and HashiCorp Packer together. CodePipeline serves as the orchestration layer, automatically triggering the pipeline whenever changes are pushed to the Git repository. CodeBuild then runs the required tests and builds the platform AMI, while Packer, executed within a CodeBuild project, creates the custom AMI that defines the new Elastic Beanstalk platform version. This combination directly addresses the need to automate custom platform version creation, as Packer is the tool specifically designed to build machine images, and CodeBuild provides the compute environment to run it. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of how to extend Elastic Beanstalk’s managed platform lifecycle with custom AMI pipelines, often tripping candidates who mistakenly choose CodeDeploy (which deploys applications, not platforms) or CloudFormation (which manages infrastructure, not image creation). Remember the key distinction: Packer builds the platform image, CodeBuild runs the build, and CodePipeline ties it all together.
DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 with a custom platform. The DevOps team wants to automate the creation of a new platform version whenever changes are pushed to a Git repository. The pipeline should run tests, build the platform, and then update the Elastic Beanstalk environment to use the new platform version. Which services should be used together to achieve this? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS CodeBuild
Options A, C, and D are correct. A: CodePipeline orchestrates the pipeline. C: CodeBuild can run tests and build the platform AMI. D: Packer (through CodeBuild) can create a custom AMI for the platform. Option B is wrong because CodeDeploy is for deploying applications, not for creating platform versions. Option E is wrong because CloudFormation is not directly used to create a custom platform; Packer and CodeBuild handle that.
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.
