- A
AWS Elastic Beanstalk
Why wrong: Elastic Beanstalk is for container-based or web apps, not serverless Lambda.
- B
AWS CodeDeploy
CodeDeploy supports Lambda canary/linear deployments and automatic rollback based on CloudWatch alarms.
- C
AWS CloudFormation with a change set
Why wrong: CloudFormation can update stack but does not support canary deployments or alarm-based rollback for Lambda.
- D
AWS CodePipeline
Why wrong: CodePipeline orchestrates stages but does not handle canary deployment or alarm-based rollback directly.

DVA-C02 Deployment Practice Question
This DVA-C02 practice question tests your understanding of deployment. 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 company wants to deploy a serverless application using AWS Lambda and API Gateway. The deployment process must support automatic rollbacks if the new version fails CloudWatch alarms. Which AWS service should be used to orchestrate this deployment?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS CodeDeploy
AWS CodeDeploy is the correct choice because it natively supports deployment strategies like canary, linear, and all-at-once, and can be configured with CloudWatch alarms to automatically trigger rollbacks when a new version fails. This makes it ideal for serverless applications using Lambda and API Gateway, where you need safe, automated deployments with health-check-driven rollback capabilities.
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.
- ✗
AWS Elastic Beanstalk
Why it's wrong here
Elastic Beanstalk is for container-based or web apps, not serverless Lambda.
- ✓
AWS CodeDeploy
Why this is correct
CodeDeploy supports Lambda canary/linear deployments and automatic rollback based on CloudWatch alarms.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
AWS CloudFormation with a change set
Why it's wrong here
CloudFormation can update stack but does not support canary deployments or alarm-based rollback for Lambda.
- ✗
AWS CodePipeline
Why it's wrong here
CodePipeline orchestrates stages but does not handle canary deployment or alarm-based rollback directly.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse CodePipeline (which orchestrates the overall pipeline) with CodeDeploy (which handles the actual deployment and rollback logic), leading them to select CodePipeline even though it lacks native automatic rollback based on CloudWatch alarms.
Detailed technical explanation
How to think about this question
AWS CodeDeploy supports Lambda deployments through its 'DeploymentConfig' parameter, which allows you to specify canary or linear traffic shifting percentages and intervals. When you associate a CloudWatch alarm with the deployment group, CodeDeploy monitors the alarm state during the deployment; if the alarm enters ALARM state, CodeDeploy automatically initiates a rollback to the previous version, stopping further traffic shifting. This is critical in production scenarios where a faulty Lambda function could degrade API performance or cause errors, and you need immediate, automated recovery without manual intervention.
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.
TExam Day Tips
- 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.
