DOP-C02 Question 335
Select 3Your company runs a critical application on AWS, and your DevOps team is responsible for ensuring high availability and quick response to incidents. Recently, a regional outage occurred, and your team was unaware of the issue until customers reported problems. To improve incident awareness and response, which combination of AWS services and configurations should you implement to detect and address regional outages proactively?
- A
Set up an EventBridge rule to capture AWS Health 'Service Event' notifications and route them to a Slack channel using an SNS topic.
- B
Enable AWS Systems Manager OpsCenter and configure it to automatically create operational items for AWS Health events.
- C
Use CloudWatch custom metrics to monitor AWS regional service health dashboards.
- D
Subscribe to Personal Health Dashboard notifications through an SNS topic for proactive alerts about service disruptions.
- E
Create a CloudWatch alarm based on the CPU utilization of EC2 instances to monitor service health.
Show answer and explanation
Correct answers: A, B, D
Explanation
To proactively detect and address regional outages, you need tools that monitor AWS service health and provide real-time notifications. Using EventBridge with AWS Health notifications, Systems Manager OpsCenter for operational item tracking, and Personal Health Dashboard notifications ensures that your team is informed of service disruptions and can respond promptly. Monitoring EC2 CPU utilization or relying on custom CloudWatch metrics alone will not provide the necessary visibility into AWS service-level health.
- A. Correct.
Correct: Setting up an EventBridge rule to capture AWS Health 'Service Event' notifications allows your team to receive real-time notifications about service disruptions, which can be routed to communication tools like Slack.
- B. Correct.
Correct: AWS Systems Manager OpsCenter can automatically generate operational items for AWS Health events, making it easier to track and manage issues effectively.
- C. Incorrect.
Incorrect: CloudWatch custom metrics cannot monitor AWS regional service health dashboards directly. AWS Health and Personal Health Dashboard are better suited for this purpose.
- D. Correct.
Correct: Subscribing to Personal Health Dashboard notifications via an SNS topic provides proactive alerts about service disruptions specific to your account and workloads.
- E. Incorrect.
Incorrect: While CloudWatch alarms on EC2 CPU utilization can provide insights into application-specific issues, they do not provide comprehensive awareness of AWS regional outages or service disruptions.
