Exam AZ-104 topic 3 question 18 discussion

Correct Answer: Box 1: Zone-redundant storage (ZRS) Zone-redundant storage (ZRS) replicates your data synchronously across three storage clusters in a single Region. GRS protects against Zone failure, while ZRS protects against data center failure. LRS would not remain available if a data center in the region fails. GRS and RA GRS use asynchronous replication. Box 2: StorageV2 (general purpose V2) ZRS only support GPv2. Reference: https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy-zrs

Answer describes ZRS being correct but marks GRS. From reading the description is seems like ZRS is the correct answer.

CORRECT

Given answer is correct

Correct

Is that only me cannot understand whether below from Microsoft Doc means ZRS is supported or not supported by BLOB: "ZRS is supported for all Azure Storage services through standard general-purpose v2 storage accounts, including: Azure Blob storage (hot and cool block blobs and append blobs, non-disk page blobs), Azure Files (all standard tiers: transaction optimized, hot, and cool), Azure Table storage, Azure Queue storage"

Pass the exam on 11 August 2023 with 909, Below are some of the notes that may help for Blob and file storage: A. Blob Storage: 1-Archive is supported in Blob Storage and General Purpose v2 (GPv2) accounts. Only storage accounts that are configured for LRS, GRS, or RA-GRS support moving blobs to the archive tier. 2-Import supports Azure Blob storage and Azure File storage 3 -Export supports Azure Blob storage 4-support Lifecycle management policies. Lifecycle management policies are supported for block blobs and append blobs in general-purpose v2, premium block blob, and Blob Storage accounts. 5-Object Replication supports General Purpose V2 and Premium Blob accounts. 6-Support both Azure (AD) and SAS (Shared Access Signature) token.

Yes, very likely you would - Passed the exam today, 1/May/23 - scored 930. I am still digesting the fact that 95% of the questions are from here, though it is tough to believe before you take the exam. Big thanks to our super-hero mlantonis!

1. ZRS 2. StorageV2 (general purpose V2) https://learn.microsoft.com/en-us/azure/storage/common/storage-redundancy#zone-redundant-storage Zone-redundant storage (ZRS) replicates your storage account synchronously across three Azure availability zones in the primary region. Each availability zone is a separate physical location with independent power, cooling, and networking. ZRS offers durability for storage resources of at least 99.9999999999% (12 9's) over a given year. https://learn.microsoft.com/en-us/azure/storage/common/storage-redundancy#standard-storage-accounts ZRS is supported for all Azure Storage services through standard general-purpose v2 storage accounts.

For reference, when people say the likes of "ZRS only support GPv2", this is not true (or perhaps no longer true). ZRS does support Premium Blob and Premium File Share 'in some regions', but these are not an option in the question. https://learn.microsoft.com/en-us/azure/storage/common/storage-account-overview

ZRS currently supports standard general-purpose v2, FileStorage and BlockBlobStorage storage account types
