Which solution will meet these requirements?
Add the instance to an EC2 Auto Scaling group with the minimum, maximum, and desired capacity set to 1.
Add the instance to an EC2 Auto Scaling group with a lifecycle hook to detach the EBS volume when the EC2 instance shuts down or terminates.
Create an Amazon CloudWatch alarm for the StatusCheckFailed System metric and select the EC2 action to recover the instance.
Create an Amazon CloudWatch alarm for the StatusCheckFailed Instance metric and select the EC2 action to reboot the instance.
Explanations:
While adding the instance to an EC2 Auto Scaling group with a capacity of 1 can help with high availability, it does not directly address quick recovery or minimizing data loss in the event of network or power issues. Auto Scaling is more useful for scaling out and handling traffic fluctuations rather than recovery from instance failures.
Adding the instance to an EC2 Auto Scaling group with a lifecycle hook to detach the EBS volume does not ensure quick recovery from connectivity issues or power failures. This method is more focused on managing EBS volume attachments rather than providing a recovery mechanism for instance-level failures.
Creating an Amazon CloudWatch alarm for the StatusCheckFailed System metric and selecting the EC2 action to recover the instance allows for automated recovery of the instance when it fails due to underlying hardware issues or system impairments. This option directly addresses the requirement for quick recovery with minimal data loss.
While creating an Amazon CloudWatch alarm for the StatusCheckFailed Instance metric and selecting the EC2 action to reboot the instance can help in some failure scenarios, it does not provide a guaranteed recovery from network issues or power failures. Rebooting may not resolve all types of failures, and recovery could take longer compared to the recovery action in option C.
