You have to create several preemptible Linux virtual machine instances using Google Compute Engine. You want to properly shut down your application before the virtual machines are preempted. What should you do?
A. Create a shutdown script registered as a xinetd service in Linux and configure an Operations Suite (formerly Stackdriver) endpoint check to call the service.
B. Create a shutdown script, registered as a xinetd service in Linux, and use the gcloud compute instances add-metadata command to specify the service URL as the value for a new metadata entry with the key shutdown-script-url
C. Create a shutdown script named k99.shutdown in the /etc/rc.6.d/ directory.
D. Create a shutdown script and use it as the value for a new metadata entry with the key shutdown-script in the Cloud Platform Console when you create the new virtual machine instance.
Correct Answer: D
Running Shutdown Scripts: Create and run shutdown scripts that execute commands right before an instance is terminated or restarted, on a best-effort basis. This is useful if you rely on automated scripts to start up and shut down instances, allowing instances time to clean up or perform tasks, such as exporting logs or syncing with other systems. https://cloud.google.com/compute/docs/shutdownscript
To setup Shutdown Scripts, go to the GCP console and follow the steps:
Compute Engine -> VM instance -> Create Instance -> (Expand) Management, disks, networking, SSH keys
Enter the key “shutdown-script” and the proper value.
