The answer is that a deployment group is a collection of deployment targets for an application, and it can target an Auto Scaling group to enable automatic deployments to new instances. This is correct because a deployment group defines the environment—such as EC2 instances, Lambda functions, or on-premises servers—where a revision is deployed, and when linked to an Auto Scaling group, CodeDeploy automatically deploys to every instance launched by that group, including those added during scale-out events. On the AWS Certified Developer Associate DVA-C02 exam, this concept tests your understanding of how CodeDeploy integrates with Auto Scaling to maintain consistent application versions across a dynamic fleet; a common trap is confusing a deployment group with a deployment configuration (which controls traffic routing and failure thresholds). Remember the mnemonic “Group for Targets, Config for Rules” to keep the distinction clear.
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.
Which TWO statements are true about AWS CodeDeploy deployment groups? (Choose two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A deployment group can use an Auto Scaling group as its target.
Option B is correct because AWS CodeDeploy deployment groups can target an Auto Scaling group, enabling automatic deployment to all instances in the group and integration with scaling events. This allows CodeDeploy to automatically deploy revisions to new instances launched by the Auto Scaling group, ensuring consistent application versions across the fleet.
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.
✗
A deployment group can only target a single EC2 instance.
Why it's wrong here
It can target multiple instances, Auto Scaling groups, etc.
✓
A deployment group can use an Auto Scaling group as its target.
Why this is correct
Auto Scaling groups are common targets.
Related concept
Read the scenario before looking for a memorised answer.
✗
A deployment group can be shared across multiple CodeDeploy applications.
Why it's wrong here
Each deployment group belongs to one application.
✓
A deployment group is a collection of deployment targets for an application.
Why this is correct
It defines where the application will be deployed.
Related concept
Read the scenario before looking for a memorised answer.
✗
A deployment group cannot be associated with a load balancer.
Why it's wrong here
It can be associated with a load balancer for traffic routing.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse deployment groups with being application-specific and think they can be shared across applications, or they incorrectly assume that deployment groups are limited to single instances or cannot integrate with load balancers.
Detailed technical explanation
How to think about this question
Under the hood, a deployment group defines the deployment configuration (e.g., AllAtOnce, HalfAtATime, or custom), the service role ARN, and optional triggers. When associated with an Auto Scaling group, CodeDeploy uses lifecycle hooks (e.g., AfterLaunch) to automatically deploy the latest revision to newly launched instances, ensuring zero-downtime scaling. In a real-world scenario, this is critical for maintaining consistent application versions during scale-out events in production environments.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
