Correct answer: Check the AWS Personal Health Dashboard for scheduled events that affect the instances..
Why this is the answer
The AWS Personal Health Dashboard (PHD) is specifically designed to provide personalized information about AWS service health and scheduled events that can affect your resources, including EC2 instances. Checking the PHD directly addresses the need to identify instances impacted by upcoming AWS hardware maintenance with minimal administrative effort, as AWS populates this information automatically. Installing and operating a third-party monitoring tool would require significant setup and ongoing management, and it wouldn't directly provide AWS's internal maintenance schedule. Opening the AWS console to check failed system status checks only shows current issues, not future scheduled maintenance. Continuously watching CloudTrail for StopInstances API calls would only show instances being stopped during maintenance, not upcoming maintenance events.
