The answer is to use AWS CodePipeline with a build stage in CodeBuild and a deploy stage that uses the ECS deploy provider. This is correct because CodePipeline’s native ECS deploy action directly updates the ECS service with a new task definition, eliminating manual intervention and following infrastructure-as-code best practices. The build stage compiles each microservice’s Dockerfile, pushes the image to Amazon ECR, and outputs the new image URI, which CodePipeline automatically injects into the task definition before deployment. On the DVA-C02 exam, this scenario tests your understanding of fully automated CI/CD pipelines for containerized workloads, where the common trap is overcomplicating the deploy stage with CodeDeploy when Fargate does not require it—CodeDeploy is only needed for blue/green deployments or canary traffic shifting. Remember the memory tip: “Pipeline to ECS, no CodeDeploy unless you need to sway.”
DVA-C02 Deployment Practice Question
This DVA-C02 practice question tests your understanding of deployment. 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 development team wants to automate the deployment of a microservices application on Amazon ECS with Fargate. The team uses AWS CodePipeline for CI/CD. Each microservice has its own source repository and Dockerfile. The team wants to build Docker images, push them to Amazon ECR, and deploy them to ECS. Which approach minimizes manual effort and follows best practices?

Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS CodePipeline with a build stage in CodeBuild and a deploy stage that uses the ECS deploy provider.
Option D is correct because CodePipeline can directly integrate with ECS using deploy actions that update the ECS service with new task definitions. Option A is wrong because it adds unnecessary manual steps. Option B is wrong because it is not a best practice to bypass CI/CD. Option C is wrong because it adds extra complexity with CodeDeploy when not needed for Fargate.
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.
✗
Use AWS CodeDeploy to deploy to ECS with a blue/green deployment.
Why it's wrong here
CodeDeploy is not needed for Fargate; ECS native deployment works.
✗
Use AWS CloudFormation to create the infrastructure and manually trigger updates.
Why it's wrong here
Manual triggers are not automated.
✓
Use AWS CodePipeline with a build stage in CodeBuild and a deploy stage that uses the ECS deploy provider.
Why this is correct
CodePipeline natively supports ECS deployment.

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

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.

Variation 1. A team is deploying a containerized application on Amazon ECS using Fargate. The application requires high availability and must be deployed across multiple Availability Zones. The team wants to automate the deployment process using AWS CodePipeline. What is the most efficient way to update the ECS service with a new task definition?
medium
✓ A.Use the ECS deploy action in CodePipeline with the 'Immediate' deployment option to update the service.
B.Use an AWS Lambda function that calls the ECS UpdateService API with the new task definition.
C.Use the AWS Management Console to update the ECS service with the new task definition.
D.Use AWS CloudFormation to update the ECS service by updating the stack with the new task definition.
Why A: Option D is correct because CodePipeline can use the ECS deploy action with the 'Immediate' deployment option to update the ECS service to use the new task definition without downtime. Option A is wrong because manually updating the service is not automated. Option B is wrong because using CloudFormation to update the stack is possible but less efficient for frequent updates. Option C is wrong because Lambda updating the service requires custom code and is more complex.
