File shares (Azure Files) - Mini Project: Build & Apply

Create and Configure an Azure File Share

📖 Scenario: You are setting up a simple file sharing service in Azure for your team to store and access shared documents securely.

🎯 Goal: Build an Azure Storage Account and create a file share with specific settings using Azure CLI commands.

📋 What You'll Learn

Create an Azure Storage Account named exactly mystorageaccount1234

Create a file share named exactly teamfiles inside the storage account

Set the file share quota to exactly 100 GB

Enable the large-file-share feature on the file share

💡 Why This Matters

🌍 Real World

Azure File Shares are used by teams to store and share files securely in the cloud accessible from anywhere.

💼 Career

Knowing how to create and configure Azure File Shares is essential for cloud administrators and infrastructure engineers managing shared storage.

1

Create the Azure Storage Account

Use the Azure CLI command to create a storage account named mystorageaccount1234 in the eastus region with the Standard_LRS SKU.

Azure

# Use az storage account create command here
# Your code here

Hint

Remember to specify the resource group with --resource-group.

2

Create the Azure File Share

Use the Azure CLI command to create a file share named teamfiles inside the storage account mystorageaccount1234.

Azure

az storage account create --name mystorageaccount1234 --resource-group myResourceGroup --location eastus --sku Standard_LRS
# Use az storage share create command here
# Your code here

Hint

Use az storage share create with the --account-name parameter.

3

Set the File Share Quota

Add the --quota option to the az storage share create command to set the quota of the teamfiles share to exactly 100 GB.

Azure

# Modify the az storage share create command to add quota
az storage share create --name teamfiles --account-name mystorageaccount1234 \
# Your code here

Hint

The quota is specified in GB using the --quota flag.

4

Enable Large File Share Feature

Update the teamfiles file share to enable the large-file-share feature using the Azure CLI command with the --enable-large-file-share flag.

Azure

az storage share create --name teamfiles --account-name mystorageaccount1234 --quota 100
# Use az storage share update command to enable large file share
# Your code here

Hint

Use az storage share update with the --enable-large-file-share true option.

Practice

1. What is the primary purpose of Azure Files in cloud infrastructure?

easy

A. To create virtual networks for Azure resources

B. To provide cloud-based file shares accessible via SMB or NFS protocols

C. To manage databases in the cloud

D. To host virtual machines in Azure

Solution

1. Step 1: Understand Azure Files functionality

   Azure Files offers file shares in the cloud that can be accessed using SMB or NFS protocols, allowing easy file sharing.

2. Step 2: Compare other options

   Options A, B, and C describe other Azure services unrelated to file sharing.

3. Final Answer:

   To provide cloud-based file shares accessible via SMB or NFS protocols -> Option B

4. Quick Check:

   Azure Files = Cloud file shares [OK]

Hint: Azure Files = cloud file shares via SMB/NFS [OK]

Common Mistakes:

• Confusing Azure Files with virtual machines
• Thinking Azure Files manages databases
• Mixing Azure Files with networking services

2. Which of the following is the correct way to set a quota for an Azure file share using Azure CLI?

easy

A. az storage file set-quota --name myshare --quota 100

B. az storage share create --name myshare --quota 100 --account-name mystorage

C. az storage account set-quota --name myshare --quota 100

D. az storage share update --name myshare --quota 100 --account-name mystorage

Solution

1. Step 1: Identify the correct Azure CLI command for setting quota

   The command to set a quota on an existing Azure file share is az storage share update.

2. Step 2: Verify command parameters

   The command requires the share name, quota size, and storage account name, matching az storage share update --name myshare --quota 100 --account-name mystorage.

3. Final Answer:

   az storage share update --name myshare --quota 100 --account-name mystorage -> Option D

4. Quick Check:

   Set quota = az storage share update [OK]

Hint: Use 'az storage share update --quota' to set file share quota [OK]

Common Mistakes:

• Using 'create' command instead of 'update'
• Confusing storage account quota with share quota
• Using incorrect command names like 'file set-quota'

3. Given the following Azure CLI commands, what will be the quota size of the file share named datafiles?

az storage share create --name datafiles --quota 50 --account-name mystorage
az storage share update --name datafiles --quota 200 --account-name mystorage

medium

A. 200 GB

B. 50 GB

C. 250 GB

D. Quota not set

Solution

1. Step 1: Analyze the initial quota setting

   The file share datafiles is created with a quota of 50 GB.

2. Step 2: Analyze the quota update command

   The quota is then updated to 200 GB using the update command, which overrides the initial quota.

3. Final Answer:

   200 GB -> Option A

4. Quick Check:

   Last quota set = 200 GB [OK]

Hint: Last quota command overrides previous quota [OK]

Common Mistakes:

• Adding quotas instead of overriding
• Assuming initial quota remains unchanged
• Ignoring the update command effect

4. You run the command az storage share update --name myshare --quota 500 --account-name mystorage but receive an error. What is the most likely cause?

medium

A. The share name contains invalid characters

B. The storage account name is missing

C. The quota value exceeds the maximum allowed size for the storage account

D. The command syntax is incorrect

Solution

1. Step 1: Check quota limits for Azure file shares

   Azure file shares have maximum quota limits depending on the storage account type. Setting a quota too large causes an error.

2. Step 2: Verify other command parts

   The share name and account name appear valid and present, and the command syntax matches the correct format.

3. Final Answer:

   The quota value exceeds the maximum allowed size for the storage account -> Option C

4. Quick Check:

   Quota too large causes error [OK]

Hint: Check quota limits before setting large sizes [OK]

Common Mistakes:

• Assuming syntax error without checking quota size
• Ignoring storage account quota limits
• Mistaking missing parameters for invalid names

5. You want to share files between multiple Azure VMs securely using Azure Files. Which of the following steps should you take to ensure secure access to the file share?

hard

A. Create an Azure file share with SMB protocol and use Azure AD authentication with role-based access control

B. Create an Azure file share with public access enabled so all VMs can connect without credentials

C. Use NFS protocol without authentication to simplify access

D. Store files locally on each VM instead of using Azure Files

Solution

1. Step 1: Identify secure access methods for Azure Files

   Azure Files supports SMB with Azure AD authentication and role-based access control to secure file shares.

2. Step 2: Evaluate other options for security

   Public access (Create an Azure file share with public access enabled so all VMs can connect without credentials) is insecure, NFS without authentication (Use NFS protocol without authentication to simplify access) is insecure, and storing files locally (Store files locally on each VM instead of using Azure Files) does not share files across VMs.

3. Final Answer:

   Create an Azure file share with SMB protocol and use Azure AD authentication with role-based access control -> Option A

4. Quick Check:

   Secure Azure Files = SMB + Azure AD + RBAC [OK]

Hint: Use SMB with Azure AD and RBAC for secure file shares [OK]

Common Mistakes:

• Enabling public access for file shares
• Using NFS without authentication
• Not using centralized file sharing
