I think the proposed answer is correct. App1: Storage1 and storage3 only App2: Storage1 and storage4 only Note: Storage2, StorageV2 with Premium Performance does NOT exist https://docs.microsoft.com/en-ca/azure/storage/common/storage-account-overview?toc=/azure/storage/blobs/toc.json#types-of-storage-accounts

App1: "Lifecycle management policies are supported for block blobs and append blobs in general-purpose v2, premium block blob, and Blob Storage accounts." from https://docs.microsoft.com/en-us/azure/storage/blobs/lifecycle-management-overview so answer is 1 and 3 (2 does not exist. go ahead, try to create one :)

While this is true, the only available option within a Lifecycle Management Policy for a premium block blob is to Delete the blob. Therefore Premium Block blobs don't have any access tiers (same as other premium storage accounts)

It's another annoying question designed to confuse you / trip you up. As other have mentioned, premium is only supported in the individual tiers, not GP v2

If you create a premium pageblob and in the portal generate an export template the ARM type is StandardV2 and the SKU.tier is Premium. In the configuration blade for the premium pageblob you can choose Hot or Cool storage tiers.

Storage2, StorageV2 with premium performance is the same as Premium Page Blobs according to this reference: https://www.ais.com/how-to-choose-the-right-kind-of-azure-storage-account/

This anwswer in the website looks wrong to me, look below the reason I say that. https://learn.microsoft.com/en-us/answers/questions/1289726/life-cycle-management-and-access-tiers "This feature is available for Blob storage (standard) accounts, GPv2 (general-purpose v2) accounts, and block blob storage accounts (premium). With lifecycle management policies, you can transition blobs between the hot, cool, and archive tiers within these supported storage accounts."

Lifecycle Management Policies: Lifecycle management policies allow you to define rules that automatically move or delete blobs based on their age or other criteria. This feature is available for Blob storage (standard) accounts, GPv2 (general-purpose v2) accounts, and block blob storage accounts (premium). With lifecycle management policies, you can transition blobs between the hot, cool, and archive tiers within these supported storage accounts.

Storage1 (Standard storage v2) can have both blobs with tiers and file shares Storage2 (Premium storage v2) does not exist. When toy select premium you have to select Block blobs, File shares, or page blobs. If you select Block blobs you will find out that there are no tiers. Because premium storage should be fast. Having a Cool access tier does not have any sense here. Storage3 (Standard BlobStorage) is technically a reference to 1 of the services in Standard Storage v2 (BlobStorage), there are other services like TableService, File Service, and Queue Service. This one can have tiers for blobs as it is the same thing as Standard Storage v2. Storage4 (Premium FileStorage) is the file storage by definition. It does not have blob storage features like life cycles and tiers.

Proposed answers are correct. - Only the Standard type/kind storage accounts support lifecycle management - Only the StorageV2 Standard offers "File shares" ("File shares" is not an option on a StorageV2 Premium) & of course the FileStorage type/kind.

It is true, I just created a StorageV2 (general purpose v2) Premium storage account in my lab & it only provides for "Containers". That's it.

Given answer is correct: App1 can use Storage 1 and 3 App2 can use Storage 1 and 4 *But* given explanation for App2 is wrong. Also, question may be outdated, since Azure uses Kind not Type. Explanation: According to this (see below), file shares are available via *both* Premium/File Shares and Standard general purpose version 2. Since Storage 1 is Type(Kind) StorageV2 and standard Tier, then App2 can use it for a file share. Since Storage 2 doesnt exist, (there is no StorageV2 Premium) then answer is not relevant. Since Storage 3 is Type(Kind) BlobStorage, then it is not suitable (see below) Since Storage 4 is Type(Kind)File Storage and Premium Tier then App2 can use it for a file share.

The provisioned model is only available for *premium* file shares, which are file shares deployed in the FileStorage storage account kind. The pay-as-you-go model is only available for standard file shares, which are file shares deployed in the *general purpose version 2* (GPv2) storage account kind."

It said in the comment box 2: Storage1 and storage4 only Azure File shares requires Premium accounts. Only Storage1 and storage4 are premium. But storage 1 is Standard so I think it should be Storage 4 only for Box 2.

I thought the same, but NFS is premium, Azure file share is on both: https://learn.microsoft.com/en-us/azure/storage/files/storage-how-to-create-file-share?tabs=azure-portal#:~:text=What%20are%20the%20performance%20requirements%20for%20your%20Azure%20file%20share%3F%0AAzure%20Files%20offers%20standard%20file%20shares%20which%20are%20hosted%20on%20hard%20disk%2Dbased%20(HDD%2Dbased)%20hardware%2C%20and%20premium%20file%20shares%2C%20which%20are%20hosted%20on%20solid%2Dstate%20disk%2Dbased%20(SSD%2Dbased)%20hardware.

https://learn.microsoft.com/en-us/azure/storage/files/storage-files-planning#management-concepts There are two main types of storage accounts you will use for Azure Files deployments: - General purpose version 2 (GPv2) storage accounts: GPv2 storage accounts allow you to deploy Azure file shares on standard/hard disk-based (HDD-based) hardware. In addition to storing Azure file shares, GPv2 storage accounts can store other storage resources such as blob containers, queues, or tables. - FileStorage storage accounts: FileStorage storage accounts allow you to deploy Azure file shares on premium/solid-state disk-based (SSD-based) hardware. FileStorage accounts can only be used to store Azure file shares; no other storage resources (blob containers, queues, tables, etc.) can be deployed in a FileStorage account. Only FileStorage accounts can deploy both SMB and NFS file shares.

So, the right is, App1 can be use 1, 2 and 3, because all of them can have a blobo to usa lifecycle, and app2 can use storage 1,2, and 4, because we can create Azure Files Share on both!
