AZ-305 Question 217
Select 2Your organization needs to migrate 80 TB of unstructured data from an on-premises file share to Azure. The on-premises site has relatively low internet bandwidth, and you want to minimize the transfer time and keep the data synchronized until the final cutover. Which two approaches should you recommend to address these requirements?
- A
Use Azure Data Box for the initial bulk data transfer and then perform incremental syncs
- B
Implement Azure File Sync to keep on-premises data synchronized with an Azure file share before final cutover
- C
Run Azure Migrate to replicate the unstructured data to Azure
- D
Implement Azure Site Recovery (ASR) to synchronize file share data into Azure
Show answer and explanation
Correct answers: A, B
Explanation
In scenarios involving large volumes of unstructured data and limited network bandwidth, combining Azure Data Box for the initial seeding with Azure File Sync for ongoing synchronization is a common best practice. Azure Data Box addresses the challenge of moving data rapidly by physically transporting drives to an Azure datacenter, while Azure File Sync efficiently replicates and updates any changed data. Azure Migrate and Azure Site Recovery do not provide the appropriate capabilities for large-scale unstructured file share migrations. Refer to Microsoft’s documentation on Azure Data Box (https://learn.microsoft.com/azure/databox) and Azure File Sync (https://learn.microsoft.com/azure/storage/file-sync/file-sync-introduction) for detailed best practices.
- A. Correct.
Azure Data Box is a secure, large-capacity data transfer solution that allows you to physically ship data to an Azure region, mitigating limited connectivity. After the initial bulk transfer, you can do incremental syncs to keep the data updated until cutover. This solution is well suited for multi-terabyte migrations with constrained bandwidth.
- B. Correct.
Azure File Sync can be used to continually synchronize on-premises file data with Azure Files, ensuring that any subsequent changes after the initial transfer are captured and replicated. This approach helps maintain a local cache on-premises while storing historical and inactive data in the cloud, reducing on-premises storage costs.
- C. Incorrect.
Azure Migrate primarily focuses on discovering, assessing, and migrating servers, VMs, and databases. It is not optimized for large-scale, unstructured data migrations from file shares, making it less appropriate for this scenario.
- D. Incorrect.
Azure Site Recovery (ASR) is designed to replicate virtual machines, not unstructured file shares. It focuses on business continuity and disaster recovery rather than bulk unstructured data migration.
