Exam AZ-305 topic 4 question 21 discussion

A lot of buzzwords in the question... Video files = block blobs... decision is whether premium block blob or general purpose v2. No premium block blob was mentioned so it has to be general purpose v2. Next is highest availability possible, and general purpose v2 supports LRS, ZRS, and GRS... so go with GRS. The expressroute connects directly to the Azure network, bypassing the internet. So private endpoint.

Its Premium Page Blobs + LRS (its the only supported redundancy for PPB) + Private Endpoint Why Premium Page Blobs : If you have a PaaS service for shared media access for collaborative video editing applications, page blobs enable fast access to random locations in the media https://docs.microsoft.com/en-us/azure/storage/blobs/storage-blob-pageblob-overview?tabs=dotnet#sample-use-cases

WRONG 1. Standard general-purpose v2 2. Geo-redundant storage (GRS) 3. A private endpoint

Standard general-purpose v2 Geo-redundant storage (GRS) A private endpoint

given answer is contradictory, Premium file share do not support GRS - MS doc - https://learn.microsoft.com/en-us/azure/storage/common/storage-account-overview Premium file we when we have requirement of performance intensive storage https://learn.microsoft.com/en-us/training/modules/describe-azure-storage-services/2-accounts answer should be - Standard V2 GRS Private links

. In addition to using virtual disks for Azure IaaS VMs, page blobs also enable PaaS and DBaaS scenarios such as Azure SQL DB service, which currently uses page blobs for storing SQL data, enabling fast random read-write operations for the database. Another example would be if you have a PaaS service for shared media access for collaborative video editing applications, page blobs enable fast access to random locations in the media. It also enables fast and efficient editing and merging of the same media by multiple users. so premium page blo lRS https://learn.microsoft.com/en-us/azure/storage/common/storage-redundancy?toc=%2Fazure%2Fstorage%2Fblobs%2Ftoc.json&bc=%2Fazure%2Fstorage%2Fblobs%2Fbreadcrumb%2Ftoc.json private endpoint

V2+GRS+PE Storage account type: Standard general-purpose v2: This supports large blob storage and is optimized for large files, such as video files of up to 7 TB. Data redundancy: Geo-redundant storage (GRS): Offers the highest availability and durability by replicating data to a secondary region. Networking: A private endpoint: Ensures secure and direct connectivity to the storage account over ExpressRoute, meeting the requirement for secure upload from the on-premises network.

The maximum file size in premium file share is 4 TiB in both standard and premium editions, so NO https://learn.microsoft.com/en-us/azure/storage/files/storage-files-scale-targets The maximum file size in premium page blob is 8TiB, which is fine https://learn.microsoft.com/en-us/rest/api/storageservices/understanding-block-blobs--append-blobs--and-page-blobs The maximum blob size in standard storage account is around 190 TiB, which is fine https://learn.microsoft.com/en-us/azure/storage/blobs/scalability-targets But only standard storage redundancy is offered by GRS. For premium version it is ZRS max. So I would go for Standard General Purpose v2 which is for large files so I think it is optimized for this purpose. I think it is possible to use premium page blob but max redundancy is ZRS which does not meet the requirement of "Provides the highest possible availability" Correct me if I am wrong...

Did we ever get a final answer the description does not match the answers

Storage-optimised video files = Premium Page Blobs The highest availability that can be achieved by choosing Premium Page Blobs is LRS. However, the question only asks to use the highest availability *possible*. Correct for Private Endpoint.

The given answer is NOT correct - my take on it Box 1: Premium Page blobs https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-pageblob-overview Box2: LRS as this is the Max redundancy option available - check table below https://learn.microsoft.com/en-us/azure/storage/common/storage-redundancy Box 3: Private endpoint since we have ER and ER to be utilized

Storage account type: - Premium page blobs. This type supports large file sizes and is optimized for large video files https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blobs-introduction Data redundancy: - Geo-redundant storage (GRS). This option provides the highest availability possible by replicating data to a secondary region. https://learn.microsoft.com/en-us/azure/storage/common/storage-redundancy Networking: - A private endpoint. This ensures the files from the on-premises network are uploaded using ExpressRoute, providing a secure and direct connection to the storage account. https://learn.microsoft.com/en-us/azure/private-link/private-endpoint-overview

Premium file share limit - 100 TB (https://learn.microsoft.com/en-us/azure/storage/files/storage-files-scale-targets) ZRS is supported for premium Azure file shares through the FileStorage storage account kind. private endpoint through Express Route

Final Answer: 1. Premium File Share 2. ZRS 3. Private Link

Page Blobs, LRS, Private endpoint. these are correct options.

Got this on today's exam (March of 2024). I selected gp v2/GRS/private endpoint for this question, and passed the exam with 870. Honestly though, even after going through the the docs and the discussion, I still don't know the answer for sure... and I guess now I will also never knew. Still, I believe I might be able to lead a happy life.

Elecktrus knows it: Elecktrus 5 months, 1 week ago I don't understand all the confusion that is being created with the answers to this question. It's very simple, you just have to see the requirements that Microsoft asks for in the correct order: 1- Provides the highest availability possible --> GRS. Ok, now, what kind of storage support GRS? --> Premium Files, no; Premium Page, no; Standar V2 Gen, yes --> Standar V2 Gen support V2 Gen files up 7 TB? --> yes Ensures that storage is optimized for the large video files --> yes Well, is clear then: Box1 = Standar V2 Gen Box1 = GRS Box3 = Private Enpoind (because we must use Express Route)
