Exam AZ-104 topic 6 question 23 discussion

I think its D. the B options needs you to shutdown the VM first, causing downtime. We must minimize downtime. Ref: https://petri.com/restore-an-azure-virtual-machines-disks-from-backup/

B. Restore VM1 by using the Replace existing restore configuration option.

🔸 “Replace existing” option will stop and deallocate the VM, and then replace the existing disks with the selected recovery point. Downtime will occur, but it is minimal. Preferred for production workloads where resource names, networking, and integrations must remain the same. https://learn.microsoft.com/en-us/azure/backup/backup-azure-arm-restore-vms#replace-existing-disks

If we focus which one is more direct approach to meet the requirements. Choice D and B sounds good thought. But, choice B does have more potential when it comes to reduce the downtime shortage.

Just to clarify: Option D (Restore VM by using the Create new restore configuration option) does not require you to deallocate or power off the existing VM, because it creates a new VM instance from the recovery point. However, while this avoids any impact to the original VM, it does not minimize downtime. You would still have to reconfigure DNS or update connections so that users start using the new VM, which takes additional time. In contrast, Option B (Restore VM by using the Replace existing option) does require you to deallocate the VM first, but it restores the disks in place, so when the VM starts back up, everything is exactly as before. This process minimizes downtime because you don't need to update any references or configurations. That’s why B is the correct answer if the priority is minimizing downtime.

Minimizing Downtime: This is the key requirement. The correct answer is D. Restore VM1 by using the Create new restore configuration option. A. Deallocate VM1: This would shut down VM1, immediately causing downtime. This is not minimizing downtime as the first step. B. Restore VM1 by using the Replace existing restore configuration option: This option replaces the disks of the existing VM1 with the disks from the chosen restore point. This requires the VM to be running to take an initial snapshot, then it replaces the disks, which will cause downtime for the existing VM while the disk replacement occurs. If the VM is running a website, this means the website will be down.

I agree that D should be correct, but Microsoft has a similar question on their practice exam and the answer they provide is to overwrite the VM :-( So unfortunately, I have to vote for B as I think this is the answer that Microsoft wants.

Replace existing restore configuration: This option restores the backup directly onto the original VM, preserving its network settings and configurations. Create new restore configuration: This option creates a new VM from the backup, requiring additional steps to update network settings, DNS, and other configurations to resume production service.

CORRECT IS D

Should be D. Restore VM1 by using the Create new restore configuration option - This option allows you to restore the VM to a new instance without affecting the current running VM. Once the restoration is successful, you can redirect traffic or swap the VMs to ensure minimal downtime. This approach provides a safer way to verify the restored VM before making it live.

Let's break this down. Since RSV1 retains daily backups for 14 days, you have a backup from eight days ago. To minimize downtime, you should avoid deleting or deallocating VM1 first. The correct initial step to recover VM1 to a point eight days ago would be: D. Restore VM1 by using the Create new restore configuration option. This way, you can restore VM1 to the desired state without affecting the existing VM's configuration.

Less downtime on new

D. Restore VM1 by using the Create new restore configuration option. This option allows you to keep the existing VM running while restoring a new instance, minimizing downtime for your static website.

The correct answer is D. Restore VM1 by using the Create new restore configuration option. To minimize downtime, you should restore VM1 to a new configuration, rather than replacing the existing one. This approach allows you to keep the current VM1 running while restoring the earlier version. Here's why the other options are not the best fit: A. Deallocating VM1 would shut it down, causing downtime. B. Replacing the existing restore configuration would overwrite the current VM1, also causing downtime. C. Deleting VM1 would result in data loss and is not a suitable option for recovery. By choosing option D, you can restore VM1 to a point eight days ago without interrupting the current VM1, minimizing downtime.

D, since we must minimize downtime
