What should the 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 an instance restarts it on the same host, which won’t resolve system check failures that often require a new host.
Stopping and then starting the instance relaunches it on a new host, which often resolves underlying hardware or networking issues causing failures.
Terminating the instance would resolve the issue but would also delete the instance, leading to potential data loss and extra setup work.
AWS CloudTrail tracks API calls but does not provide information on system health or host-level issues, making it unhelpful for resolving this issue.
If memory serves me right, the answer is:
Stop and then start the EC2 instance so that it can be launched on a new host.
I sort that the answer is:
Stop and then start the EC2 instance so that it can be launched on a new host.
