Deployment, Provisioning, and Automation →mediumMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is to create a blue/green deployment by configuring CodeDeploy to launch new instances and shift traffic after validation. This approach achieves zero downtime because the old environment (blue) continues serving traffic through the Application Load Balancer while the new environment (green) is fully provisioned and health-checked, ensuring no capacity is reduced or disrupted during the transition. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this scenario tests your understanding of deployment strategies under the “Deploying with AWS Services” domain, where a common trap is confusing in-place deployments with blue/green—in-place updates can cause downtime by replacing instances one at a time. A key memory tip is to think “blue stays live until green is given the green light,” reinforcing that traffic shifts only after validation.

SOA-C02 Deployment, Provisioning, and Automation Practice Question

This SOA-C02 practice question tests your understanding of deployment, provisioning, and 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 company uses AWS CodeDeploy to deploy a new version of an application to EC2 instances in an Auto Scaling group behind an Application Load Balancer. The company requires zero downtime during the deployment. Which deployment configuration 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

✓

Create a blue/green deployment by configuring CodeDeploy to launch new instances and shift traffic after validation.

Option D is correct because a blue/green deployment with CodeDeploy, where new instances are launched and traffic is shifted only after validation, ensures zero downtime by keeping the old environment (blue) fully serving traffic until the new environment (green) is verified healthy. This approach avoids any in-place updates that could temporarily reduce capacity or cause service disruption, meeting the requirement for zero downtime during 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.

  • ✗

    CodeDeployDefault.AllAtOnce

    Why it's wrong here

    Incorrect. AllAtOnce updates all instances simultaneously, causing downtime if the new version fails.

  • ✗

    CodeDeployDefault.OneAtATime

    Why it's wrong here

    Incorrect. While it reduces risk, it does not inherently provide zero downtime; the ALB still routes traffic to instances being updated unless connection draining is configured.

  • ✗

    CodeDeployDefault.EC2/OnPremises: BlueGreenDeployment

    Why it's wrong here

    Incorrect. This is not a standard deployment configuration name; CodeDeploy blue/green uses a separate deployment style configuration.

  • ✓

    Create a blue/green deployment by configuring CodeDeploy to launch new instances and shift traffic after validation.

    Why this is correct

    Correct. Blue/green deployment with CodeDeploy allows routing traffic to new instances and cutting over after validation, ensuring zero downtime.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse the predefined deployment configurations (like AllAtOnce or OneAtATime) with the blue/green deployment method, not realizing that blue/green is a separate deployment type configured in the deployment group settings, not a predefined configuration name.

Detailed technical explanation

How to think about this question

In a blue/green deployment with CodeDeploy, the deployment group is configured to launch new instances in a separate Auto Scaling group (green) behind the same Application Load Balancer, and traffic is shifted using the ALB's target group routing rules—either immediately or gradually via a canary or linear traffic shift. The old instances (blue) remain active until the deployment is complete and can be terminated or kept for rollback, ensuring zero downtime because the ALB only routes traffic to healthy targets in the green environment after validation. This contrasts with in-place deployments where the same instances are updated, which can cause a temporary reduction in capacity or failed health checks if the deployment hooks (e.g., BeforeInstall, AfterInstall) require a service restart.

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.
