Question 347 of 1,750
Troubleshoot Failed Deployments
This DOP-C02 practice question tests your understanding of incident and event response. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: aWS CloudTrail. 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 DevOps engineer is troubleshooting a failed deployment. The engineer needs to identify the root cause. Which TWO AWS services can provide information about the deployment events and errors? (Choose two.)

Correct answer & explanation
✓
AWS CloudTrail
AWS CloudTrail records API calls made in your account, including deployment actions such as those from CodeDeploy, CloudFormation, or Elastic Beanstalk. It provides event history for troubleshooting failed deployments by showing who made what call and when. AWS Config tracks configuration changes to AWS resources, including deployment-related changes. It can show the state of resources before and after a deployment, helping identify misconfigurations that caused the failure. The other options are incorrect: AWS Trusted Advisor offers best-practice checks and cost optimization recommendations, not deployment event logging. AWS Service Catalog manages approved IT services and product portfolios, not deployment events. Amazon Inspector is a vulnerability assessment service for security, not deployment troubleshooting.

Key takeaway
AWS CloudTrail
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
