An organization uses Azure File Sync to synchronize local file shares from an on-premises … — Microsoft Azure Administrator (AZ-104)

An organization uses Azure File Sync to synchronize local file shares from an on-premises server named Server1 to Azure. Server1 has a single volume E: with a total capacity of $2\text{ TB}$ ( $2,000\text{ GB}$ ). The volume contains $200\text{ GB}$ of local, non-sync data that cannot be tiered.

The administrator configures two server endpoints on volume E: as follows:
- The folder E:\\DepartmentA ( $800\text{ GB}$ of files, with only $50\text{ GB}$ of files older than $30\text{ days}$ ) is added to SyncGroup1. The cloud tiering volume free space policy is set to $15\%$ and the date policy is set to $30\text{ days}$ .
- The folder E:\\DepartmentB ( $600\text{ GB}$ of files, with only $50\text{ GB}$ of files older than $14\text{ days}$ ) is added to SyncGroup2. The cloud tiering volume free space policy is set to $35\%$ and the date policy is set to $14\text{ days}$ .

What will be the final amount of free space on volume E: after the initial synchronization and cloud tiering processes complete?

A
$500\text{ GB}$
B
$300\text{ GB}$
$700\text{ GB}$ Answer
D
$900\text{ GB}$

Answer

The correct answer is

700\text{ GB}

because the effective volume free space target of

35\%

on the

2,000\text{ GB}

volume must be satisfied, which requires maintaining

700\text{ GB}

of free space. Since date-based tiering only frees up space to

500\text{ GB}

, the volume free space policy overrides the date constraint to tier more files until the

700\text{ GB}

target is met.

The correct option is the one stating that the final free space is

700\text{ GB}

. When multiple server endpoints reside on the same volume, the effective volume free space policy is the maximum value configured among all server endpoints on that volume, which is

35\%

. For a

2,000\text{ GB}

volume, this translates to maintaining a minimum of

700\text{ GB}

of free space. Although evaluating the individual date policies first tiers

100\text{ GB}

of data, leaving the volume with

500\text{ GB}

of free space, this is still less than the

700\text{ GB}

target. Because the volume free space policy takes precedence over the date-based policy, Azure File Sync will override the date constraints and tier an additional

200\text{ GB}

of the coldest files across both server endpoints to achieve the required

700\text{ GB}

of free space.

Step-by-Step Solution

Determine the effective volume free space policy for volume E:.

The effective policy is

35\%

When multiple server endpoints reside on the same volume, Azure File Sync applies the maximum of the configured volume free space policies on that volume (

\\max(15\%, 35\%) = 35\%

Calculate the target volume free space to be maintained on volume E:.

Target free space is

700\text{ GB}

The total capacity of volume E: is

2,000\text{ GB}

. The target free space is calculated as

35\% \\times 2,000\text{ GB} = 700\text{ GB}

Calculate the initial free space on volume E: and apply the date-based tiering policies.

Free space after date-based tiering is

500\text{ GB}

Initial used space is

200\text{ GB} \\text{ (non-sync)} + 800\text{ GB} \\text{ (Endpoint A)} + 600\text{ GB} \\text{ (Endpoint B)} = 1,600\text{ GB}

, leaving

400\text{ GB}

free. Applying the date policies tiers

50\text{ GB}

from Endpoint A and

50\text{ GB}

from Endpoint B, totaling

100\text{ GB}

tiered, which increases the free space to

500\text{ GB}

Determine the final cloud tiering action based on policy precedence.

Final free space is

700\text{ GB}

Since the free space of

500\text{ GB}

is less than the target of

700\text{ GB}

, the volume free space policy takes precedence. The system overrides the date policy constraints and tiers an additional

200\text{ GB}

of the coldest files across both endpoints to achieve the required

700\text{ GB}

of free space.
