A company has deployed a fleet of Amazon EC2 web servers for the upcoming release of a new product.The SysOps Administrator needs to test the AmazonCloudWatch notification settings for this deployment to ensure that a notification is sent using Amazon SNS if the CPU utilization of an EC2 instance exceeds 70%.

How should the Administrator accomplish this?

Use the set-alarm-state command in AWS CloudTrail to invoke the Amazon SNS notification

Use CloudWatch custom metrics to set the alarm state in AWS CloudTrail and enable Amazon SNS notifications

Use EC2 instance metadata to manually set the CPU utilization to 75% and invoke the alarm state

Use the set-alarm-state command in the AWS CLI for CloudWatch

Explanations:

Theset-alarm-statecommand is not part of AWS CloudTrail. CloudTrail records API calls and does not manage alarm states directly.

CloudWatch custom metrics are not needed for this scenario, and CloudTrail does not set the alarm state. Custom metrics and CloudTrail are unrelated in this context.

Manually setting the CPU utilization through EC2 instance metadata is not a practical approach to test CloudWatch alarms and will not trigger an alarm directly.

Theset-alarm-statecommand in the AWS CLI can be used to simulate an alarm state for testing purposes. This is the correct method to test the CloudWatch alarm and SNS notification.
