Difficulty: HardConfigure Azure Files and Azure File Sync

An organization plans to sync an on-premises folder `D:\Marketing` on a file server named `Server1` to an Azure file share named `mktg-share` using Azure File Sync. The local drive `D:` has a total capacity of 1 TB1\text{ TB} (1000 GB1000\text{ GB}). The configuration must meet the following requirements:
- Drive `D:` must always maintain at least 300 GB300\text{ GB} of free space.
- Files that have not been accessed for more than 30 days30\text{ days} must be moved to the cloud.
- The administrator who registers `Server1` must be granted the minimum necessary permissions to perform the registration.
Which two configurations should you implement? (Select two.)

  1. Create a server endpoint for `D:\Marketing` with cloud tiering enabled, a volume free space policy of 30%30\%, and a date policy of 30 days30\text{ days}.Answer
  2. B
    Create a server endpoint for `D:\Marketing` with cloud tiering enabled, a volume free space policy of 70%70\%, and a date policy of 30 days30\text{ days}.
  3. Assign the Storage Sync Service Administrator role to the user account used to register `Server1`.Answer
  4. D
    Assign the Storage Blob Data Contributor role to the user account used to register `Server1`.
  5. E
    Generate a Shared Access Signature (SAS) token for the storage account with a 30 days30\text{ days} validity period and configure it on `Server1`.

Answer

The correct configurations are to create a server endpoint for `D:\Marketing` with cloud tiering enabled, a volume free space policy of 30%30\%, and a date policy of 30 days30\text{ days}, and to assign the Storage Sync Service Administrator role to the user account used to register `Server1`.
To maintain at least 300 GB300\text{ GB} of free space on a 1000 GB1000\text{ GB} volume, the volume free space policy must be configured to 30%30\% (since 3001000×100=30%\frac{300}{1000} \times 100 = 30\%). Enabling cloud tiering with both the volume free space policy and the date policy of 30 days30\text{ days} ensures both file age and space criteria are enforced. Additionally, registering a server to a Storage Sync Service requires permissions on the sync service, for which the Storage Sync Service Administrator role provides the minimum required privileges.

Step-by-Step Solution

1
Calculate the volume free space percentage required for the volume free space policy.
The required percentage is 30%30\%.
To maintain at least 300 GB300\text{ GB} of free space on a 1000 GB1000\text{ GB} drive, the volume free space policy must be configured as 3001000×100=30%\frac{300}{1000} \times 100 = 30\%.
2
Identify the minimum required RBAC role for the administrator to register the server with the Storage Sync Service.
The Storage Sync Service Administrator role.
This role provides the minimum necessary permissions to register a server without granting excessive control plane access like Contributor or Owner on the resource group.
3
Identify the correct configurations from the options based on the calculations and role requirements.
Select the option specifying a 30%30\% volume free space policy and the option assigning the Storage Sync Service Administrator role.
These two selections satisfy all given constraints, including the date policy of 30 days30\text{ days} and minimum administrative permissions.
