AWS Certified SysOps Administrator – Associate — Question 178

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: C

Explanation

The correct answer is C because the Amazon CloudWatch agent can provide detailed disk space metrics from the Windows instances, allowing for precise monitoring and alerting. Option A is incorrect as it doesn't mention the CloudWatch agent, which is necessary for detailed metrics. Option B is wrong because CloudTrail is not designed for monitoring resource usage like disk space. Option D is also incorrect since AWS Trusted Advisor does not provide real-time monitoring and alerting for EBS volume space.
