Question 1,240 of 1,546
Deployment, Provisioning, and AutomationhardMultiple SelectObjective-mapped

Quick Answer

The answer is to add a step in the pipeline to register the task definition using the AWS CLI or SDK, along with ensuring the pipeline’s deploy action references the correct revision. This resolves the failure because CodePipeline’s ECS deploy action requires a registered task definition ARN before it can update the service; if the new definition isn’t registered first, the deployment has nothing to apply. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this tests your understanding of the deployment sequence in CodePipeline—specifically that task definition registration is a separate, prerequisite action from the ECS service update. A common trap is confusing ECR (which stores container images) with the task definition (which is a JSON blueprint stored in ECS), or assuming the pipeline automatically registers the definition. Remember the order: register the task definition first, then deploy—think “register before you deploy” to avoid the failure.

SOA-C02 Deployment, Provisioning, and Automation Practice Question

This SOA-C02 practice question tests your understanding of deployment, provisioning, and automation. 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 deploys microservices on Amazon ECS using Fargate. The deployment is managed by AWS CodePipeline. The administrator notices that deployments sometimes fail because the new task definition is not registered before the deployment. Which THREE steps should the administrator take to resolve this issue? (Choose THREE.)

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

Ensure that the task definition is registered in the CodePipeline build stage before the deploy stage.

The issue is that the task definition must be registered before the ECS service update. Options A, D, and E are correct. Option B is wrong because the task definition is not stored in ECR; ECR stores container images. Option C is wrong because the ECS service update is triggered by CodePipeline, not manually.

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.

  • Ensure that the task definition is registered in the CodePipeline build stage before the deploy stage.

    Why this is correct

    The build stage should register the new task definition. Without it, the deploy stage may fail.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Manually update the ECS service with the new task definition after the pipeline runs.

    Why it's wrong here

    Manual intervention defeats the purpose of automation.

  • Use the ECS deploy action in CodePipeline which automatically registers the task definition.

    Why this is correct

    The ECS deploy action can be configured to register the task definition from a file.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Add a step in the pipeline to register the task definition using the AWS CLI or SDK.

    Why this is correct

    This ensures the task definition is registered before deployment.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Store the task definition in Amazon ECR alongside the container image.

    Why it's wrong here

    ECR stores container images, not task definitions.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

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.
