Exam AZ-301 topic 6 question 4 discussion

Sorry but what a kind of nasty question is this??? - GRS is not an option: GRS is not an option because, the files in failover region are only accessible in case of failover of the primary region. - File Sync is not an option because: Azure File Sync can be used only for Shared File but not blob storage - DFS => Distributed File Sytem, is this an Azure Service? I dont think so. - RA-GRS: This is for desaster recovery not for productive application usage. In addition to that you are not able to select the "secondary region". The secondary region so called "paired region" is fixed and defined by microsoft. I do not think that I need to know every paired region for a selected region. In this case, east region is realy the paired region for the west region. See list of paired region here: https://docs.microsoft.com/en-us/azure/best-practices-availability-paired-regions

Given answer is correct, As data needs to be read either of the locations.

Ignore my previous comment , it is blob not file share !! , so correct would be RA-GRS as grs will not be readable in the secondary region

why not Azure file sync , users will have access to the nearest server and update the data once on the other server it will be synced

C. read-access geo-redundant storage (RA-GRS)

May be options given are not added exactly which question had in real exam. Because none of the options justify the given scenario. GRS and RA-GRS are disaster recovery options, comes into the picture when a failover occurs. Requesting admin to recheck the options.

given answer is correct.

Solution should be. "C. read-access geo-redundant storage (RA-GRS)" But there was confusion because the secondary region is not allowed to be mentioned while creating an SA with RA-GRS. I tried to create an SA with RA-GRS in East US and now it shows secondary as West US. But if the same question comes up with different region, I would be confused. Did not find any documentation mentioning secondary region for each primary region.

Ensure that the users receive files from the same region as the web app that they access. So it means that RA-GRS is correct answer as the data must be accessible in the second region too.

To Test-Taker: 'updated' is correct (not 'uploaded'). '• Ensure that the files only need to be updated once ' means data is updated only in Primary Region (as it is the only Region when we can Write data). All RA-GRS Replicas are Read-Only and we can't update data in there

FYI, in the requirements of the question, "updated" is supposed to be "uploaded"

Given answer is right

This is a typical scenario for DFS. DFS enables you to synchronize files to different locations (which is the case), and each webapp can map the shared folder in the same region, which is the requested requirenment. Also, when a file is uploaded, this file will be synchronized to the other path of the DFS, which is another requirement, that the file need to be uploaded once.

Did the question change? The requirements read as "✑ Ensure that the users receive files from the same region as the web app that they access." I don't see where it reads that users need to be able to access/read the data from the secondary region. So on that basis I think the answer is GRS.

Since it states that they use Blob Storage to Deliver files, we have to assume that the users are only reading (downloading) the files, and it states that they have to be able to do that from both regions, therefore, RA-GRS is the only option, as it allows Read from both locations.

The solution is to use Azure file sync. The web app will write/read from the storage account in the same region and the azure file sync will replicate the data to the other region.

Requirement mentions Ensure that the users receive files from the same region as the web app that they access. So the answer should be GRS.
