Topic 1 Question 66
Your application is running on Compute Engine and is showing sustained failures for a small number of requests. You have narrowed the cause down to a single Compute Engine instance, but the instance is unresponsive to SSH. What should you do next?
Reboot the machine.
Enable and check the serial port output.
Delete the machine and create a new one.
Take a snapshot of the disk and attach it to a new machine.

Difficult to choose because either B(https://cloud.google.com/compute/docs/troubleshooting/troubleshooting-ssh#debug_with_serial_console) or D(https://cloud.google.com/compute/docs/troubleshooting/troubleshooting-ssh#inspect_vm) is recommended by google. I'd stay with B.
👍 4donchick2020/12/21Option-B is most suitable: In a real world I will try this and even if doesn't work then I will try Option-D which will help me to troubleshoot in details.
👍 4StelSen2021/02/19I would take B as the answer
"What should you do next?"
SSH is port 22 so it makes sense to check for the port
