Microsoft Certified: Azure Developer Associate (AZ-204)Develop for Azure storageMedium
A company is migrating an on-premises application that stores configuration files and shared log files on a network file share. The application requires a file system interface (SMB/NFS) and needs to be accessible from multiple Azure Virtual Machines simultaneously. The solution must also provide built-in redundancy within a single Azure region.
- AAzure Queue Storage
- BAzure Blob Storage
- CAzure Files with Zone-Redundant Storage (ZRS)
- DAzure Table Storage
Show answer & explanationAnswer & explanation
Correct answer: C. Azure Files with Zone-Redundant Storage (ZRS)
Azure Files provides managed file shares that can be accessed via SMB or NFS protocols, making it suitable for lift-and-shift scenarios from on-premises network file shares. Zone-Redundant Storage (ZRS) ensures data redundancy across different availability zones within a single Azure region, meeting the requirement for built-in redundancy.
Why the other options are wrong
- A. Azure Queue Storage is for message queuing, not file storage.
- B. Azure Blob Storage is object storage, not a file system with SMB/NFS access.
- D. Azure Table Storage is a NoSQL key-value store, not a file system.
Azure Files with ZRS
Azure Files offers fully managed file shares in the cloud, accessible via standard SMB and NFS protocols. Zone-Redundant Storage (ZRS) ensures data is synchronously replicated across three Azure availability zones in the primary region, providing high availability.
- Provides SMB/NFS file shares.
- Accessible from multiple VMs simultaneously.
- ZRS offers redundancy within a single region across availability zones.
Memory trick: Azure Files is for familiar File Shares, ZRS for Zone Safety.
