  1. What is the purpose of Azure Blob Storage versioning?

    Answer: Tracks and stores every previous version of a blob automatically

    Blob versioning automatically saves the state of a blob every time it is modified, allowing you to restore or access any previous version.

  2. Which Azure Storage redundancy option provides read access to a secondary region in the event of primary region unavailability?

    Answer: RA-GRS

    Read-access geo-redundant storage (RA-GRS) replicates data to a secondary region and provides a secondary read endpoint that is always accessible.

  3. What is the correct way to copy a large number of blobs between storage accounts efficiently using command-line tools?

    Answer: Use AzCopy with the copy command and service-to-service transfer

    AzCopy supports server-side service-to-service transfers for blobs, copying data between storage accounts without passing through the client machine.

  4. Which class in the Azure Storage SDK for .NET is used to interact with a specific blob container?

    Answer: BlobContainerClient

    BlobContainerClient represents a specific container and provides methods for listing blobs, creating blobs, and managing container properties.

  5. What is the purpose of the ETag header returned in Azure Blob Storage responses?

    Answer: Enables optimistic concurrency by representing the current blob version

    The ETag is a version identifier for a blob; you can supply it in If-Match conditions to perform optimistic concurrency updates only if the blob hasn't changed.

  6. Which Azure Storage feature enables automatic failover of a storage account to the secondary region without manual intervention?

    Answer: Microsoft-managed failover (automatic) available with GRS/RA-GRS during outages

    Microsoft-managed automatic failover can trigger for GRS/RA-GRS accounts during severe regional outages where Microsoft determines failover is necessary.
