Exam AZ-104 topic 3 question 15 discussion

This is one of those ridiculous questions that would imply we should memorize the 50 different combinations of storage type, replication type, versus live migration support. Useless info to keep in your head, why would they test for this. The support rules around live migration support are horrendous. Bleh.

Answer is correct. It is storage2. The key to the answer in this question is "Live migration" - You can do Live migration to ZRS from LRS or GRS only. - Also this only applies on General Purpose v2 storage.

Tip BlobStorage do not support Zone-Redundant Storage (ZRS) as a replication option.

B is correct Live Migration = Storage V2 + LRS or GRS

To identify which storage account can be converted to Zone-redundant storage (ZRS) replication by requesting a live migration from Azure support, you should identify the following: The storage account that you want to convert to ZRS replication, in this case, Storage2. Provide justification or reasons for the conversion, such as the need for higher resilience and redundancy across availability zones within an Azure region. Confirm that the storage account meets the prerequisites for ZRS replication, such as being a StorageV2 account and currently configured with Locally-redundant storage (LRS) replication. By providing this information and justification to Azure support, you can request a live migration of Storage2 to Zone-redundant storage (ZRS) replication. Azure support will assess the request based on the provided details and perform the necessary actions to convert the storage account to ZRS replication.

B is correct

Horrible question , currently how solutions architect professional in AWS , Azure is too horrible in question of certification the question only need memorized a lot of combinations exactly steps , why ? no have idea

This question appeared in latest exam in September 2023. The correct answer is , Live migration can be done to ZRS from LRS if the type is General purpose V2.

Storage 2 https://www.youtube.com/watch?v=-0LvU_g4Ksk&list=PLlKA5U_Yqgof3H0YWhzvarFixW9QLTr4S&index=64

storage1 -> NO, because the “(Standard) general purpose v1” does not support ZRS … I’ve put “Standard” in parenthesis because the documentation I’ve found do not mention about *premium* general purpose v1, but since it is not specified I suppose the same limitations apply to it. storage2 -> YES : the migration from LRS to ZRS is supported, and excluding the other options only this one remains. storage3 -> NO : the conversion from “…from GRS/RA-GRS” requires “Switch to LRS first”. storage4 -> NO: the “BlobStorage” kind, is a “Legacy blob storage” that does not support ZRS.

Agree with B Answer looks correct; https://learn.microsoft.com/en-us/azure/storage/common/redundancy-migration?tabs=portal

Since ZRS is only supported by StorageV2 only B and C would apply. Live migration is not possible for RA-GRS (option C). Option B remains.

Exactly same question was on todays exam. (7th April 2023)

I took Exam of Azure- 104 at 27/2/2023 I score 920 points out of 1000 points. This was on it and my answer was: B

B- storage2 - ZRS Supports the following Storage Account Types: Standard GPv2 Accounts Premium File Share Accounts Premium Block Blob Accounts - Conversion is just supported for GPv2 and Premium File Share storage accounts (Not for Blob Accounts). - Convertion from GRS/RA-GRS to ZRS, Switch to LRS first (Directly from RA-GRS is not possible). According to these info; - Storage1 is GPv1 so NO - Storage3 is RA-GRS so NO - Storage4 is BlobStorage so NO Source: https://learn.microsoft.com/en-us/azure/storage/common/redundancy-migration?tabs=portal

On my 2nd test

B) "storage2" ZRS Supports the following Storage Account Types: - Standard General-purpuse v2 Accounts - Premium File Share Accounts - Premium Block Blob Accounts Reference: https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy#zone-redundant-storage
