Question

Difficulty: MediumConfigure Azure Files and Azure File Sync

Your company has an on-premises file server named Server1 that contains a 1000 GB1000\text{ GB} volume D:. You deploy Azure File Sync and configure a sync group containing an Azure file share cloud endpoint and a server endpoint targeting the `D:\Data` folder.

You need to configure the cloud tiering settings to meet the following requirements:
- Maintain a minimum of 200 GB200\text{ GB} of free space on volume D:.
- Cache files locally if they have been accessed within the last 14 days14\text{ days}, unless the volume free space constraint requires additional tiering.

Which configuration should you specify, and which policy will take precedence?

  1. A
    Volume Free Space policy set to 80%80\% and Date policy set to 14 days14\text{ days}; the Date policy takes precedence.
  2. B
    Volume Free Space policy set to 20%20\% and Date policy set to 14 days14\text{ days}; the Date policy takes precedence.
  3. Volume Free Space policy set to 20%20\% and Date policy set to 14 days14\text{ days}; the Volume Free Space policy takes precedence.Answer
  4. D
    Volume Free Space policy set to 80%80\% and Date policy set to 14 days14\text{ days}; the Volume Free Space policy takes precedence.

Answer

Volume Free Space policy set to 20%20\% and Date policy set to 14 days14\text{ days}; the Volume Free Space policy takes precedence.
To maintain 200 GB200\text{ GB} of free space on a 1000 GB1000\text{ GB} volume, you must set the Volume Free Space policy to 20%20\%. Setting the Date policy to 14 days14\text{ days} ensures that files not accessed within this window are tiered first. In the event of a conflict, the Volume Free Space policy takes precedence to protect the local volume from running out of space.

Step-by-Step Solution

1
Calculate the percentage required for the Volume Free Space policy.
The required free space is 200 GB200\text{ GB} out of a total volume capacity of 1000 GB1000\text{ GB}, which is 20%20\% (200 GB/1000 GB=20%200\text{ GB} / 1000\text{ GB} = 20\%).
The Volume Free Space policy specifies the percentage of capacity that must remain free on the local volume.
2
Identify the Date policy configuration.
The Date policy is set to 14 days14\text{ days}.
This guarantees that files accessed within the last 14 days14\text{ days} remain locally cached under normal circumstances.
3
Determine the precedence rules between the two policies.
The Volume Free Space policy takes precedence.
Under Azure File Sync rules, if both policies are enabled, the Volume Free Space policy always overrides the Date policy to prevent the local disk from running out of space.
