The answer is a three-step pipeline: a source stage with CodeCommit, a build stage with CodeBuild to build the Docker image and push it to Amazon ECR, and a deploy stage with ECS. This sequence is correct because CodePipeline orchestrates the continuous delivery of containerized applications by pulling source code, compiling it into a Docker image stored in ECR, and then updating the ECS service with a new task definition that references that image. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this question tests your understanding of native AWS services for container CI/CD, often appearing as a scenario where you must distinguish between ECS and EC2 deployment targets. A common trap is selecting CodeDeploy for the deploy stage, but CodeDeploy is designed for EC2/on-premises or Lambda, not ECS—ECS uses its own deploy action. Another trap is thinking Lambda is needed to trigger the deployment, but ECS handles that natively. Memory tip: think "Source, Build, Push, Deploy" or simply "Commit, Build, ECR, ECS."
DOP-C02 SDLC Automation Practice Question
This DOP-C02 practice question tests your understanding of sdlc automation. 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.
Which THREE steps are required to set up a continuous deployment pipeline using AWS CodePipeline that deploys a Docker-based application to Amazon ECS? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a source stage that uses AWS CodeCommit as the source provider
Options A, C, and D are correct. A source stage with CodeCommit stores the code; a build stage with CodeBuild builds and pushes the Docker image to ECR; a deploy stage with ECS deploys the new task definition. Option B is wrong because CodeDeploy is for EC2/on-premises, not ECS. Option E is wrong because Lambda is not used for ECS deployment.
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.
✗
Create a deploy stage that uses AWS CodeDeploy to deploy to Amazon ECS
Why it's wrong here
CodeDeploy is not the primary deploy method for ECS; ECS deploy provider is used.
✓
Create a source stage that uses AWS CodeCommit as the source provider
Why this is correct
CodeCommit is the source for the application code and Dockerfile.

✓
Create a deploy stage that uses Amazon ECS as the deploy provider with an imagedefinitions.json file
Why this is correct
ECS deploy provider updates the service with the new image.

✗
Create an invoke stage that uses AWS Lambda to update the ECS service
Why it's wrong here
Lambda is not needed; ECS deploy provider handles this.
✓
Create a build stage that uses AWS CodeBuild to build a Docker image and push it to Amazon ECR
Why this is correct
CodeBuild builds the image and pushes to ECR.

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.
