You want to make a copy of a production Linux virtual machine in the US-Central region. You want to manage and replace the copy easily if there are changes on the production virtual machine. You will deploy the copy as a new instance in a different project in the US-East region.
What steps must you take?
To replicate a production Linux virtual machine to another region and project within Google Cloud Platform, creating a snapshot of the root disk and then generating an image file in Google Cloud Storage is the best approach. This way, the image can be accessed and used to create a new VM instance in a different project and region. Directly using snapshots may not be straightforward across different projects and regions.
D is correct. A and B are talking about appending the file system to a new VM, not setting it at the root in a new VM set. Option C is not offered within the GCP because the image must be on the GCP platform to run the gcloud of Google Console instructions to create a VM with the image.
D is ok
you are incorrect. It is D
Why Not B. https://cloud.google.com/compute/docs/instances/create-start-instance#createsnapshot This clearly tells we can use snapshot to create a VM instance, and only need a custom image if we need to create many instances. Here we are creating only one.
You can't use the snapshot created by another project
According to the documentation we can now https://cloud.google.com/compute/docs/disks/create-snapshots
I think the question has 2 different answers now as Google improve the snapshot function. Quoted from the link: 'You can create snapshots from disks even while they are attached to running instances. Snapshots are global resources, so you can use them to restore data to a new disk or instance within the same project. You can also share snapshots across projects.'
B would have been the answer in the current context. But as I read carefully, it doesnt mention the step of sharing snapshot across projects. It directly expects to use the snapshot. Hence D may be the right answer!
Only if its in the same zone: https://cloud.google.com/compute/docs/disks/create-snapshots#sharing_snapshots "Note: The disk must be in the same zone as the instance." But this is not the case here, we have: Different zones and different project hence, you must use a bucket.
https://cloud.google.com/compute/docs/instances/copy-vm-between-projects#zonal-boot-disk
https://cloud.google.com/compute/docs/instances/copy-vm-between-projects you have to create Image from Snapshot and share it to the destination project.
Currently , It is possible to create VM from snapshot within same project, different project or even different organisation. so answer B is more straight forward.

B is the right one as of 01/2023
B is incorrect as it doesnt create an image uses the snapshot and hence D is the only corret option
https://cloud.google.com/compute/docs/instances/copy-vm-between-projects
B isn't correct because you have to create a disk first. You cannot create a VM from a snapshot directly. gcloud compute disks create DISK_NAME \ --source-snapshot SNAPSHOT_NAME \ --project SOURCE_PROJECT_ID \ --zone ZONE
D is the right answer, B would be a good answer if mentioned to share the snapshot with other project
D is correct
D is the correct answer
B is the correct answer, We can create VM from snapshot across zones and regions, please read through the link, https://cloud.google.com/compute/docs/instances/moving-instance-across-zones#moving-an-instance-manually
D seems better, but B actually works too.
B is the correct answer and It is straight forward.
No, B is not correct, try your answer in GCP. Yo will not see your snapshot, because in different regions you don't have visibility of snapshots, that's why we need to move it to Cloud Storage first.
B is correct
We neet to move from one region o another, so we need snapshot of the root disk and send it to Cloud Storage. In the scenario of using in the same region, it is better tu use instance image, not snapshots of root disk.
