Topic 1 Question 46
You have an outage in your Compute Engine managed instance group: all instances keep restarting after 5 seconds. You have a health check configured, but autoscaling is disabled. Your colleague, who is a Linux expert, offered to look into the issue. You need to make sure that he can access the VMs. What should you do?
Grant your colleague the IAM role of project Viewer
Perform a rolling restart on the instance group
Disable the health check for the instance group. Add his SSH key to the project-wide SSH Keys
Disable autoscaling for the instance group. Add his SSH key to the project-wide SSH Keys

C, is the correct answer. As per the requirement linux expert would need access to VM to troubleshoot the issue. With health check enabled, old VM will be terminated as soon as health-check fails for the VM and new VM will be auto-created. So, this situation will prevent linux expert to troubleshoot the issue. Had it been the case that stack-drover logging is enabled and the expert just want to view the logs from the Cloud-logs than role to project-viewer could help. But it is specifically mentioned that expert will login into VM to troubleshoot the issue and not looking at the cloud Logs. So, Option-C is the correct answer.
