AWS Certified SysOps Administrator – Associate (legacy) — Question 26

A SysOps Administrator is required to monitor free space on Amazon EBS volumes attached to Microsoft Windows-based Amazon EC2 instances within a company's account. The Administrator must be alerted to potential issues.
What should the Administrator do to receive email alerts before low storage space affects EC2 instance performance?

Answer options

• A. Use built-in Amazon CloudWatch metrics, and configure CloudWatch alarms and an Amazon SNS topic for email notifications
• B. Use AWS CloudTrail logs and configure the trail to send notifications to an Amazon SNS topic
• C. Use the Amazon CloudWatch agent to send disk space metrics, then set up CloudWatch alarms using an Amazon SNS topic
• D. Use AWS Trusted Advisor and enable email notification alerts for EC2 disk space

Correct answer: A

Explanation

Option A is correct because it directly utilizes Amazon CloudWatch metrics to monitor EBS volume space and sets up alarms to notify the Administrator via Amazon SNS. Option B is incorrect as AWS CloudTrail logs provide a different type of monitoring focused on API usage, not disk space. Option C is not the best choice here because while it involves using the CloudWatch agent, the built-in metrics from CloudWatch are sufficient for this requirement. Option D does not provide real-time monitoring and alerts, making it less effective for addressing low storage issues.
