A company provisioned an Amazon FSx for Windows File Server with tight storage capacity and created an SNS topic subscribed to a SysOps administrator's email. The administrator must receive an email alert when available free space on the file system falls below 100 GB. Which combination of actions will fulfill this requirement? (Choose two.)

To monitor and alert on Amazon FSx for Windows File Server free space, CloudWatch is the appropriate service. The FreeStorageCapacity metric for FSx for Windows File Server is available in CloudWatch. Therefore, creating a CloudWatch alarm that triggers when this metric falls below 100 GB (100,000,000,000 bytes) is the correct first step. CloudWatch alarms can directly publish notifications to an Amazon SNS topic when they transition to an ALARM state. This eliminates the need for an intermediate service like AWS Lambda or Amazon EventBridge for this specific alerting scenario. EventBridge is not designed to directly monitor CloudWatch metrics for threshold breaches; its primary use is for event-driven architectures based on events from AWS services or custom applications.
