The answer is AWS CodeDeploy, as it is the dedicated service for automating application deployments to Auto Scaling Groups (ASGs) while ensuring zero downtime. CodeDeploy integrates directly with ASGs to perform rolling updates, gradually replacing instances with the new application version so that traffic continues to flow through the Application Load Balancer without interruption. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your ability to distinguish between infrastructure management and application deployment—CloudFormation handles infrastructure, not code pushes, while OpsWorks and Elastic Beanstalk are broader platforms. A common trap is choosing CloudFormation because it can update ASGs, but it cannot deploy application code directly. Remember the memory tip: “CodeDeploy for code, CloudFormation for cloud”—if the task is pushing a new app version to running instances, CodeDeploy is the correct tool.
SOA-C02 Deployment, Provisioning, and Automation Practice Question
This SOA-C02 practice question tests your understanding of deployment, provisioning, and 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.
A company wants to deploy a new version of a web application to an Auto Scaling group of EC2 instances behind an Application Load Balancer. The deployment should be automated and must not cause downtime. Which AWS service should be used?
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 integrates with Auto Scaling groups and supports rolling updates to minimize downtime. CloudFormation can manage infrastructure but not application deployment directly. OpsWorks and Elastic Beanstalk are options but CodeDeploy is the dedicated service for application 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.
✗
AWS CloudFormation
Why it's wrong here
CloudFormation is for infrastructure provisioning, not application deployment.
✗
AWS OpsWorks
Why it's wrong here
OpsWorks is for configuration management, but CodeDeploy is more appropriate for automated deployments.
✗
AWS Elastic Beanstalk
Why it's wrong here
Elastic Beanstalk is a PaaS service, but the question specifically asks for deployment to an existing Auto Scaling group.
✓
AWS CodeDeploy
Why this is correct
CodeDeploy automates application deployments to EC2 instances, including Auto Scaling groups.

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.
