Question 26
In the europe-central2-a zone, your team has an application server running on Compute Engine. What should you do to ensure high availability and replicate this server to europe-central2-b zone in as few steps as possible?
-
A
You should create a snapshot from the disk and then create a disk from this snapshot in the
europe-central2-bzone. Finally, create a new virtual machine with that disk. -
B
You should use
gcloudtool to copy the drive to theeurope-central2-bzone and then create a new virtual machine with this disk. -
C
You should create a snapshot from the disk and then create a disk from this snapshot in the
europe-central2-azone, move this disk toeurope-central2-band finally create a new virtual machine with that disk. -
D
You should use
gcloudtool to copy the drive to theeurope-central2-azone, move this disk toeurope-central2-band finally create a new virtual machine with this disk.
Reveal correct answer
Correct answer: A
A.
Creating a snapshot of the disk is the quickest and easiest way to replicate an application server running on Compute Engine from one zone to another. A snapshot is a point-in-time copy of a disk that can be used to create a new disk in another zone or region. By creating a snapshot of the disk and then creating a new disk in the europe-central2-b zone, you can ensure that the data is replicated in as few steps as possible.
B.
It suggests using the gcloud tool to copy the drive to the europe-central2-b zone and then creating a new virtual machine with this disk. This option is not as efficient as creating a snapshot because it requires copying the entire drive, which may take longer and consume more resources.
C.
It suggests creating a disk from the snapshot in the same zone, moving the disk to the europe-central2-b zone and then creating a new virtual machine with that disk. This option adds an extra step of moving the disk to the new zone, which is not necessary since a disk can be created directly in the desired zone from the snapshot.
D.
It suggests using the gcloud tool to copy the drive to the europe-central2-a zone, moving the disk to europe-central2-b and then creating a new virtual machine with that disk. This option is also not as efficient as creating a snapshot since it involves an additional step of moving the disk between zones.
