  1. Which Azure Storage redundancy option keeps three copies of data within a single physical location in the primary region?

    Answer: Locally redundant storage (LRS)

    LRS replicates data three times within a single data center in the primary region.

  2. Which storage redundancy option synchronously replicates data across three availability zones in the primary region?

    Answer: ZRS

    Zone-redundant storage (ZRS) copies data across three availability zones within the primary region.

  3. What is the primary benefit of geo-redundant storage (GRS) over LRS?

    Answer: Protection against a regional outage

    GRS copies data to a secondary region, protecting against a full regional outage.

  4. Which Azure Storage service is best suited for storing large amounts of unstructured data such as images and videos?

    Answer: Azure Blob Storage

    Azure Blob Storage is optimized for storing massive amounts of unstructured object data.

  5. Which access tier in Azure Blob Storage offers the lowest storage cost but the highest access cost and latency?

    Answer: Archive tier

    The Archive tier has the lowest storage cost but data must be rehydrated before access.

  6. Which Azure storage service provides fully managed file shares accessible via the SMB protocol?

    Answer: Azure Files

    Azure Files offers managed cloud file shares accessible through SMB and NFS.

  7. What does read-access geo-redundant storage (RA-GRS) add compared to standard GRS?

    Answer: Read access to the secondary region

    RA-GRS allows read access to data in the secondary region even when the primary is available.
