Exam AZ-800 topic 5 question 6 discussion

AS007 , you are wrong if you have data onprem in other server, why you will pay to Azure to get you data again? and that will take forever From: https://techcommunity.microsoft.com/t5/storage-at-microsoft/introduction-to-data-deduplication-in-windows-server-2012/ba-p/424257 3) Portability: A volume that is under deduplication control is an atomic unit. You can back up the volume and restore it to another server. You can rip it out of one Windows 2012 server and move it to another. Everything that is required to access your data is located on the drive. All of the deduplication settings are maintained on the volume and will be picked up by the deduplication filter when the volume is mounted. The only thing that is not retained on the volume are the schedule settings that are part of the task-scheduler engine. If you move the volume to a server that is not running the Data Deduplication feature, you will only be able to access the files that have not been deduplicated.

A. Create a storage pool. - Makes no sense B. Restore files from Azure Backup. - Data back up still dedup, so not only cost but one more step to add the role on new server C. Install the File Server Resource Manager server role. - makes no sense D. Install the Data Deduplication server role. - correct

D. Install the Data Deduplication server role.

To swiftly access all the files on Disk2 after connecting it to Server2, you should install the Data Deduplication server role. Here’s why: Data Deduplication: Disk2 is already configured for deduplication on Server1. When you move Disk2 to Server2, the deduplication settings are retained. The deduplication filter recognizes the volume as an atomic unit, including all deduplication settings. You’ll be able to access the deduplicated files directly without unpacking the entire data. No additional efforts are required

FYI this is a question straight from the MeasureUp practice exam. The correct answer is B - sorry to all you D'ers out there!

"'Atomic units' mean that all of the deduplication information about a given volume is kept on that volume, so it can be moved without injury to another system that supports deduplication. If you move it to a system that doesn't have deduplication, you'll only be able to see the nondeduplicated files. The best rule is not to move a deduplicated volume unless it's to another Windows Server 2012 machine."

If you already have Server2 and the disk is connected to it, installing the Data Deduplication role could potentially help you save storage space on the disk by eliminating duplicate data. However, it won't necessarily speed up the process of accessing the files immediately, as the deduplication process may take some time, especially if it's a large dataset. On the other hand, restoring files from Azure Backup is a quicker way to access and recover the files from the backup without needing to perform deduplication or additional data processing. This is especially important when your goal is rapid data recovery after a server failure. So, while installing the Data Deduplication role may be beneficial for storage efficiency in the long term, if your primary concern is quick access to the files on the disk, restoring files from Azure Backup is the more suitable and faster option.

B is correct

It's restore from Azure Backup. Reason: Yup can't use Disk 2 on other mechine if you don't de-dupicate it first on Server 1, and since it failed it won't be much of a use.

"Disk2 is configured for deduplication" D is the answer

B, because you want it as quickly as possible.

B. Restore files from Azure Backup. This will restore the files on Disk2 that were protected by Azure Backup, and will ensure that you can access all the files on Disk2 as quickly as possible. Option D, installing the Data Deduplication server role, may not be the best solution because the deduplication process can take a significant amount of time and resources to complete. Additionally, the deduplication metadata may not be accessible if the disk is connected to a different server and the data deduplication feature is not installed on that server.

is te fastest way to get you data back.

Since it says restore as quickly as possible, the fastest way would be to attach the disk to server 2 and enable dedup to be able to work with the files imo. Azure backup will work but wont be the quickest assuming its a reasonable size file share.

Key piece of info or assumption, server failed not the disk. If that's the case then no data lost and no back restore required. But then data is dedup so you need role which can ensure that you can read

You should restore the files from Azure Backup on Server B. Azure Backup is used to back up files and folders and recover from Azure. You can restore the data using the restore feature of Azure Backup. You can select the latest restore point and mount the data on Server B. This meets the goal because you can restore the data on Disk A and provide access to the domain users group. You should not install the Data Deduplication role on Server B. Data Deduplication is used to reduce the impact of redundancies on storage costs. Disk A has deduplication enabled. You need to disable the deduplication for Disk A before mounting on Server B to access the data. Since Server A is not booting up. you cannot disable the deduplication feature for Disk A. Hence, installing the Deduplication role on Server B would not help and this would not meet the goal.

"Disk2 is configured for deduplication." + "you can access all the files on Disk2 as quickly as possible.". This rules out Azure Backup, because it does not fulfill the "quick as possible" condition. Install the Data Dedup role on the server and the disk is up and running almost instantly.
