What should the SysOps Administrator do first to resolve this issue?
Reboot the EC2 instance so it can be launched on a new host.
Stop and then start the EC2 instance so that it can be launched on a new host.
Terminate the EC2 instance and relaunch it.
View the AWS CloudTrail log to investigate what changed on the EC2 instance.
Explanations:
Rebooting the EC2 instance does not necessarily resolve the system check failures, as it will not change the host.
Stopping and then starting the EC2 instance will launch it on a new physical host, which can resolve system check failures caused by underlying hardware issues.
Terminating the EC2 instance and relaunching it is unnecessary if the issue can be resolved by stopping and starting the instance. This would lead to data loss if no backups exist.
Viewing AWS CloudTrail logs helps with investigation but will not immediately resolve the system check failure. Troubleshooting through stopping and starting the instance should be the first step.
I plot that the answer is:
Stop and then start the EC2 instance so that it can be launched on a new host.
I evaluate that the answer is:
Stop and then start the EC2 instance so that it can be launched on a new host.
