Exam AZ-103 topic 2 question 14 discussion

given answer is correct

Except that Blob Storage doesn't support page blobs (which aren't excluded). I used the pricing calculator and couldn't see a different in price between blogstorage and v2. Since v2 is the "recommended option" that's probably the right answer (https://azure.microsoft.com/en-us/pricing/details/storage/blobs/)

Correct

V2 and GRS. reason- V2 support the storage types needed in the question and GRS provide geo redundancy. so that provide fault tolerance during region failure.

why standard-GRS and not RA-GRS. don't they speak about minimizing cost?

"General-purpose v2 accounts deliver the lowest per-gigabyte capacity prices for Azure Storage, as well as industry-competitive transaction prices." as per https://docs.microsoft.com/en-us/azure/storage/common/storage-account-overview Since a requirement is to minimize cost, GPv2 takes the cake. So GPV2 and Standard_GRS are my answers.

Answer is right , BlobStorage accounts – This is a legacy storage account. Use General-purpose v2 account as much as possible. General-purpose v2 accounts – This is recommended for most scenarios. This storage account type provides the blob, file , queue and table service.

We recommend you use GPv2 instead of Blob storage accounts for tiering. GPv2 support all the features that Blob storage accounts support plus a lot more. Pricing between Blob storage and GPv2 is almost identical, but some new features and price cuts will only be available on GPv2 accounts.

This answer is correct.

This is right based on this https://docs.microsoft.com/en-us/azure/storage/common/storage-account-overview

Should I use Blob storage or GPv2 accounts if I want to tier my data? We recommend you use GPv2 instead of Blob storage accounts for tiering. GPv2 support all the features that Blob storage accounts support plus a lot more. Pricing between Blob storage and GPv2 is almost identical, but some new features and price cuts will only be available on GPv2 accounts. GPv1 accounts don't support tiering. Pricing structure between GPv1 and GPv2 accounts is different and customers should carefully evaluate both before deciding to use GPv2 accounts. You can easily convert an existing Blob storage or GPv1 account to GPv2 through a simple one-click process. For more information, see Azure storage account overview.

Cost for Blob and Storage V2 is the same (actually Storage V2 transaction/operations price is higher). The answer should be BlobStorage, which meets all three critiera of the question - i.e., 1) Minimizes cost, 2) Supports Hot, cool, archive blob tiers //note the hint 3) provides fault tolerance (both blob and storage V2 support GRS)
