Q72 — AWS DOP-C02 Ch.1

Question 72 of 100 | ← Chapter 1

A company’s developers rely on system administrators from a third-party IT services firm to perform maintenance tasks. The company operates several Amazon EC2 instances requiring restart after AWS Health notifications during scheduled maintenance windows. The DevOps engineer must implement an automated remediation solution using Amazon EventBridge to respond to planned maintenance notifications.

• A. Configure AWS Health as the event source. Specify event types indicating planned instance termination and retirement. Target an AWS Systems Manager Automation runbook to restart the EC2 instances. ✓
• B. Configure Amazon Systems Manager as the event source. Specify event types indicating maintenance windows. Target an AWS Systems Manager Automation runbook to restart the EC2 instances.
• C. Configure AWS Health as the event source. Specify event types indicating planned instance termination and retirement. Target a newly created AWS Lambda function that registers an SSM Maintenance Window task to restart the EC2 instances.
• D. Configure Amazon EC2 as the event source. Specify event types representing instance state notifications. Target a newly created AWS Lambda function that registers an SSM Maintenance Window task to restart the EC2 instances.

Correct Answer: A. Configure AWS Health as the event source. Specify event types indicating planned instance termination and retirement. Target an AWS Systems Manager Automation runbook to restart the EC2 instances.

Explanation

AWS Health is the authoritative service for publishing planned maintenance events (e.g., EC2 instance retirement). Option A correctly sets AWS Health as the event source, selects relevant event types (planned termination/retirement), and directly targets an SSM Automation runbook — enabling immediate, reliable remediation without intermediate components. Option C adds unnecessary complexity with Lambda and SSM Maintenance Windows. Options B and D use incorrect event sources: Systems Manager does not emit maintenance notifications, and EC2 instance state events are unrelated to AWS-scheduled maintenance. Therefore, Option A is correct.
