Question 1,104 of 1,750
Automate Lambda Deployment with CodePipeline on CodeCommit Push
This DOP-C02 practice question tests your understanding of sdlc automation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 developer wants to automatically deploy a new version of an AWS Lambda function whenever code is pushed to a specific branch in AWS CodeCommit. Which combination of services should be used?
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 CodeCommit, Amazon EventBridge, AWS CodePipeline
Option A is correct because AWS CodePipeline can be configured with a source stage that uses AWS CodeCommit as the source provider, and an Amazon EventBridge rule can detect push events to a specific branch in CodeCommit. When a push occurs, EventBridge triggers the pipeline execution, which then deploys the new Lambda function version automatically. This combination provides a fully managed, event-driven CI/CD pipeline for Lambda deployments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✓
AWS CodeCommit, Amazon EventBridge, AWS CodePipeline
Why this is correct
EventBridge can detect CodeCommit push events and trigger CodePipeline.

- ✗
AWS CodeCommit, Amazon S3, AWS Lambda
Why it's wrong here
S3 is not necessary for this workflow.
- ✗
AWS CodeCommit, AWS CodeBuild
Why it's wrong here
CodeBuild alone does not deploy Lambda functions automatically.
- ✗
AWS CodeCommit, Amazon CloudWatch Logs
Why it's wrong here
CloudWatch Logs only stores logs.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think a direct Lambda trigger from CodeCommit (via S3 or CloudWatch Logs) is sufficient, but they overlook the need for a pipeline service like CodePipeline to manage the deployment workflow and handle versioning, rollbacks, and approvals.
Detailed technical explanation
How to think about this question
Under the hood, EventBridge uses a rule with a pattern matching the 'ReferenceType' as 'branch' and 'referenceName' as the specific branch (e.g., 'main') on CodeCommit repository events. The pipeline's source stage polls or receives the event, then passes the commit ID to subsequent stages, which can include a deployment action using AWS Lambda or AWS CloudFormation to update the function code. This event-driven approach avoids polling and reduces latency compared to periodic checks.
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 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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A team wants to automatically deploy a new version of a Lambda function when code is pushed to a CodeCommit repository. Which AWS service should orchestrate this workflow?
easy- A.AWS CodeDeploy
- B.AWS CodeBuild
- ✓ C.AWS CodePipeline
- D.AWS CloudFormation
Why C: AWS CodePipeline is the correct service because it is a fully managed continuous delivery service that orchestrates the entire release process, including source code changes from CodeCommit, building with CodeBuild, and deploying to Lambda. It can automatically trigger a pipeline execution when a new commit is pushed to a CodeCommit repository, enabling automated deployment of the Lambda function.
