[All AZ-304 Questions]

HOTSPOT -
You have an on-premises file server that stores 2 TB of data files.
You plan to move the data files to Azure Blob storage in the Central Europe region.
You need to recommend a storage account type to store the data files and a replication solution for the storage account. The solution must meet the following requirements:
✑ Be available if a single Azure datacenter fails.
✑ Support storage tiers.
✑ Minimize cost.
What should you recommend? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Suggested Answer:
Box 1: Blob storage -
Blob storage supports storage tiers
Note: Azure offers three storage tiers to store data in blob storage: Hot Access tier, Cool Access tier, and Archive tier. These tiers target data at different stages of its lifecycle and offer cost-effective storage options for different use cases.
Box 2: Zone-redundant storage (ZRS)
Data in an Azure Storage account is always replicated three times in the primary region. Azure Storage offers two options for how your data is replicated in the primary region:
✑ Zone-redundant storage (ZRS) copies your data synchronously across three Azure availability zones in the primary region.
✑ Locally redundant storage (LRS) copies your data synchronously three times within a single physical location in the primary region. LRS is the least expensive replication option, but is not recommended for applications requiring high availability.

i am fine with V2, but second one should be GRS because of single data center fails. one region could have 2 or more DC, if only one fails, your data is still safe if it is GRS. considering min cost....

To minimise cost use standard not premium. GPv2 is recommended as a default by MS ZRS is cheapest option that supports a data centre failure

Answer : Storage V2 and ZRS. ZRS is pretty obvious. But why you should choose Storage V2 rather than Blob storage ? Because if you deploy a storage account and want only Blod, then you need to select a premium storage. Premium Blobs are more expansive than the Blobs you have in your Storage V2. Question says : minimize the cost. So you can't choose Blob Storage (premium) or worse (legacy blob storage......). You can't choose Storage V1 since they don't support access tiers.

Supported storage account types The following table shows which redundancy options are supported by each type of storage account. For information for storage account types, see Storage account overview. SUPPORTED STORAGE ACCOUNT TYPES LRS ZRS GRS/RA-GRS GZRS/RA-GZRS General-purpose v21 General-purpose v1 Premium block blob1 Legacy blob Premium file shares General-purpose v21 Premium block blobs1 Premium file shares General-purpose v21 General-purpose v1 Legacy blob General-purpose v21

I think storage V2 is the correct answer as I think that is what Microsoft is pushing us to use in the future. I heard the other storage types will be phased out eventually.

"What should you recommend?" I assume by "Blob" the option is actually Standard Blob storage (legacy), which should never be recommended. In any case, it doesnt support LRS. Described as "legacy blob" in the table here: https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy

Hi Guys, look at the question itself: "You plan to move the data files to Azure Blob storage in the Central Europe region", it has highlighted that data will move to BLOB Storage, so the question here is narrowed to that is the Storage V2 under BLOB Storage?

https://docs.microsoft.com/en-us/azure/storage/common/storage-account-overview#types-of-storage-accounts Data must be available if a single Azure datacenter fails. It means the storage account must support ZRS replication. Also, solution should support storage tiers. Only General-purpose V2 supports ZRS and storage tiers. Account type is V2 and replication is ZRS

syu31svc is just saying that you need both for the solution, Blob does support storage tiers but doesn't support zone replication: "Data must be available if a single Azure datacenter fails. It means the storage account must support ZRS replication."
