You have a Recovery Services vault named RSV1. RSV1 has a backup policy that retains instant snapshots for five days and daily backup for 14 days.
RSV1 performs daily backups of VM1. VM1 hosts a static website that was updated eight days ago.
You need to recover VM1 to a point eight days ago. The solution must minimize downtime.
What should you do first?
To minimize downtime, you should first restore VM1 by using the Create new restore configuration option. This creates a new VM from the backup taken eight days ago without affecting the currently running VM. Once the new VM is up and running, you can test it to ensure it meets your requirements. Once confirmed, you can then switch over to the new VM, which results in minimal disruption to the current live environment. This approach avoids taking the existing VM offline during the restoration process, thereby minimizing downtime as required.
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/
NOT Option D, "Restore VM1 by using the Create new restore configuration option," may not be the best option because it creates a new virtual machine, which means you will have to recreate the virtual machine's configuration and re-provision resources. This can result in longer downtime and more complex configurations. In contrast, the Replace existing restore configuration option allows you to restore the virtual machine to a specific point in time while preserving the existing virtual machine configuration and resources. This minimizes downtime and eliminates the need to recreate the virtual machine's configuration, making it a more efficient solution for recovery.
I think option D is correct - Even if it takes longer to create new VM the question only asks to "minimize downtime". Creating a new VM lets you to not touch the production website while still enables you to restore from backup and test the website independently. Once you are satisfied, it would be a simple switch that result in close to 0 downtime.
What resources need to be re provisioned ? maybe changing IP addresses after switching off the old VM .. ... right ? All other configuration will be preserved on the new restored VM
J'ai passé mon examen le 24/02/2023 avec une réussite de 810 points. Je vous conseille de faire tous les exercices, car il y a 70% de questions d'examen ici.
You have to speak in English here.
No creo
it's pretty clear what he's said: he passed with a 810 score and 70% of exam questions matched the ones in this site
while i know that most of the questions are from the site, these random bot posts leave a bad taste in my mouth. no person would complete the exam, then come back to literally the 500th question of the dump and post about their results. that's what the initial landing page is for.

They said they passed their exam 24 Feb 2023 with a score of 810. They advise you do all the exercises because this makes about 70% of the questions of the exam.
B: let me explain why. Some folks are saying that D is better because that means the App is still running, while we create a new instance (and I assume then you would swap slots or however you plan on doing it). But let's suppose that the App you have is creating orders. And its creating them wrong. What was the point of keeping it up, just so you can keep making bad orders, which you still need to fix. I dunno, maybe fixing bad orders (if even possible) is better than losing any orders because you are done 100% for some period of time. I still think B as yes you are down, but not for that long and it doesn't say avoid doing bad things by leaving the app up, or any other things than minimize downtime and I still feel B does it better, with less ramifications to whatever the issue WAS that made you decide to take it down in the first place
I see your points but it is not apt to make assumptions that the App is creating wrong orders. The questions explicitly asks for a solution that will minimize downtime. This is an indication that the App is in active operation. D makes more sense as the time taken to create new restore configuration does not affect the App. And once the new config is up and ready, swapping the slots offers less downtime to [B] ie Restore VM1 by using the Replace existing restore configuration option. I will stick with D
The assumption about orders was just an example. Nobody restores a website or any after, after an update, unless they realize something was wrong and they just figured it out.. So take the app down, otherwise the scenario makes no sense (well thats sort of standard for many of the questions anyway lol)
it's one of the problems with MS exams, that we need to start involving philosophy to try and figure out the correct answer. For me, the fact that the app was somehow surviving for 8 days and only then it was noticed or decision was made to revert it indicates that it is still alive and working in a reduced capacity, so they don't want to kill it for a long time, just the minimum amount of time to revert the changes. On the other hand, you could say that maby the service was dead for the entire 8 days while the support team was working around the clock to revive it (because lets say the update is mandatory and required for compliance) and now they have given up and because of all the missed SLAs and opportunities the management wants it back up pronto. my kneejerk reaction would be to restore in place - B, because that's the least administrative effort. but if we want the least downtime it would be D, because switch between two VMs would be really fast. So personally i'm sticking with D
B. Restore VM1 by using the Replace existing restore configuration option - This option would restore the VM backup over the existing VM. This means it would replace the current VM with the backup version from eight days ago. However, if there's any problem during the restore process, the VM could remain in an inconsistent state. 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. The best approach in terms of minimizing downtime and ensuring a safe restoration process would be to: D. Restore VM1 by using the Create new restore configuration option.
I will go with B as if we need to restore that means something already not working (so downtime clock already started) and replacing disk looks faster than restore somewhere else playing with it
B. The question did mention: "VM1 hosts a static website" A static website is like a text file, one should not (almost) cause any harm to another. So no point to wait full restore and should be almost no risk to restore it directly.
B. Restore VM1 by using the Replace existing restore configuration option. Here's why this option is the best choice: Deallocating VM1 (Option A) would stop the virtual machine, causing downtime, which is not aligned with the goal of minimizing downtime. Deleting VM1 (Option C) would permanently remove the virtual machine, and you would lose all your data and configurations. This is not a suitable option if you want to retain your VM with the data up to eight days ago. Restoring VM1 by using the "Create new restore configuration" (Option D) would create a new virtual machine, which may lead to additional downtime, and you might need to reconfigure it to match the original VM's settings.
In this scenario, where you need to recover VM1 to a point eight days ago while minimizing downtime, the appropriate action would be to choose the "Replace existing" option. Here's why: Recovery Point: The requirement is to recover VM1 to a point eight days ago. Since the daily backups retain data for 14 days, there should be a backup available from around eight days ago. Minimize Downtime: Choosing the "Replace existing" option ensures that the restored VM1 will replace the current VM1 instance, minimizing downtime. This option replaces the entire VM with the backup version, including its disks, configuration, and data. It's typically faster than creating a new VM and copying data back. Therefore, the first step would be to initiate the restore operation and choose the "Replace existing" option to restore VM1 to the desired point in time while minimizing downtime.
Faster for you does not automatically mean less downtime. Option D is correct: even if you spend a full week fiddling with the settings, and in-place restore would take just five minutes, downtime for simply entering a new ip address in your load balancer (for example) would be much less.
D is correct
Creating new restore configuration will no minimize downtime.
Given the necessity to minimize downtime, restoring VM1 using the "Create new" restore configuration option (Option D) is the more prudent first step. This way, a new VM is created from the eight-day-old backup, and once it's confirmed that the restoration is successful and the static website is as expected, the DNS or load balancer settings can be updated to point to the new VM, thus achieving a minimized downtime. https://learn.microsoft.com/en-us/azure/backup/backup-azure-arm-restore-vms

B is a better option than D because minimizing downtime is the priority.
D is correct
just think on less downtime, on B more downtime is expected, so answer is D, no matters what is going wrong here.
D. Is the option with the least downtime.
D minimizes downtime & risk.
