You are about to perform a major software upgrade on a critical Compute Engine instance. You want to ensure you can quickly revert to the current state if the upgrade fails.
What should you do FIRST?
Answer options:
A.
Create a custom image from the instance.
B.
Take a snapshot of the instance's persistent disk.
C.
Export the disk to a Cloud Storage bucket.
D.
Enable auto-healing on the instance.
How to approach this question
Identify the standard backup mechanism for Compute Engine disks.
Full Answer
B.Take a snapshot of the instance's persistent disk.✓ Correct
A persistent disk snapshot is a point-in-time backup of the data on your disk. Taking a snapshot before a risky operation (like an OS upgrade) is a best practice. If something goes wrong, you can create a new disk from the snapshot and attach it to the VM, effectively rolling back the changes.
Common mistakes
Confusing Images and Snapshots. Images are for deployment (bootstrapping new VMs); Snapshots are for backup and recovery.
