Answer: Disable the health check for the instance group. Add his SSH key to the project-wide SSH Keys
The correct answer is C: 'Disable the health check for the instance group. Add his SSH key to the project-wide SSH Keys.' Since the instances are restarting every 5 seconds, the health check might be failing and causing the instances to restart. Disabling the health check will prevent managed instance group from automatically recreating the instances, giving your colleague stable access to troubleshoot. Adding his SSH key to the project-wide SSH Keys will allow him to SSH into the instances and investigate the issue directly.
