[All AWS Certified DevOps Engineer - Professional DOP-C02 Questions]

A company has a fleet of Amazon EC2 instances that run Linux in a single AWS account. The company is using an AWS Systems Manager Automation task across the EC2 instances.

During the most recent patch cycle, several EC2 instances went into an error state because of insufficient available disk space. A DevOps engineer needs to ensure that the EC2 instances have sufficient available disk space during the patching process in the future.

Which combination of steps will meet these requirements? (Choose two.)

A. Ensure that the Amazon CloudWatch agent is installed on all EC2 instances.
B. Create a cron job that is installed on each EC2 instance to periodically delete temporary files.
C. Create an Amazon CloudWatch log group for the EC2 instances. Configure a cron job that is installed on each EC2 instance to write the available disk space to a CloudWatch log stream for the relevant EC2 instance.
D. Create an Amazon CloudWatch alarm to monitor available disk space on all EC2 instances. Add the alarm as a safety control to the Systems Manager Automation task.
E. Create an AWS Lambda function to periodically check for sufficient available disk space on all EC2 instances by evaluating each EC2 instance's respective Amazon CloudWatch log stream.

A. Ensure that the Amazon CloudWatch agent is installed on all EC2 instances. The Amazon CloudWatch agent can collect system-level metrics, including disk space usage, and send them to Amazon CloudWatch. This will allow you to monitor the available disk space on each EC2 instance. D. Create an Amazon CloudWatch alarm to monitor available disk space on all EC2 instances. Add the alarm as a safety control to the Systems Manager Automation task. By setting up a CloudWatch alarm to monitor the available disk space, you can trigger actions or notifications when the disk space falls below a certain threshold. Adding this alarm as a safety control to the Systems Manager Automation task ensures that the patching process will only proceed if there is sufficient available disk space.
