Question

Difficulty: MediumConfigure Azure Files and Azure File Sync

Your company has an on-premises Windows Server named FileServer-West1 that has a single volume E: with a total capacity of 2 TB (2,000 GB). You implement Azure File Sync to synchronize volume E: with an Azure file share.

You need to configure Azure File Sync cloud tiering to meet the following requirements:
* A minimum of 400 GB of free space must always be maintained on volume E:.
* Files that have not been accessed or modified within the last 14 days must be cached in the cloud, provided the volume free space target is not compromised.

How should you configure the cloud tiering settings on the server endpoint?

  1. Enable cloud tiering, set the Volume Free Space policy to 20%, and enable the Date policy set to 14 days.Answer
  2. B
    Enable cloud tiering, set the Volume Free Space policy to 400 GB, and enable the Date policy set to 14 days.
  3. C
    Configure an Azure Blob Storage Lifecycle Management policy on the destination storage account to tier files to the Cool tier after 14 days of inactivity.
  4. D
    Enable cloud tiering on the server endpoint, assign the Storage File Data Privileged Reader role to the registered server, and generate a SAS token with a 14-day expiration.

Answer

Enable cloud tiering, set the Volume Free Space policy to 20%, and enable the Date policy set to 14 days.
The correct configuration requires enabling cloud tiering on the server endpoint, setting the Volume Free Space policy to 20% (since 400 GB is 20% of the 2 TB volume capacity), and enabling the Date policy set to 14 days. When both policies are enabled, the Volume Free Space policy takes precedence to ensure that the specified local volume free space is maintained.

Step-by-Step Solution

1
Calculate the required Volume Free Space percentage.
The target free space is 400 GB out of a total volume capacity of 2 TB (2,000 GB). The percentage is calculated as follows:
400 GB2000 GB×100%=20%\frac{400\text{ GB}}{2000\text{ GB}} \times 100\% = 20\%
Note that Azure File Sync cloud tiering requires specifying the free space as a percentage.
Azure File Sync cloud tiering's Volume Free Space policy is defined as a percentage from 0% to 100% of the volume's total capacity.
2
Determine the configuration of the Date policy.
The Date policy must be enabled and set to 14 days.
This policy tiers files that have not been accessed or modified within the specified number of days to the cloud, as long as the Volume Free Space policy threshold is not violated.
3
Configure the server endpoint settings.
Apply the cloud tiering configuration directly to the server endpoint.
Azure File Sync cloud tiering policies are configured at the server endpoint level within the Storage Sync Service.
