The configuration process begins within an Azure Storage Account, where administrators must select the appropriate performance tier—Standard (HDD-based) for general workloads or Premium (SSD-based) for high-IOPS applications—and define the replication strategy (LRS, ZRS, or GRS) for data durability.
A critical aspect of configuration is managing access tiers. Administrators switch between Transaction Optimized, Hot, and Cool tiers to align storage costs with data access patterns. Security configuration is paramount; this includes setting up identity-based authentication using Azure Active Directory Domain Services (Azure AD DS) or on-premises Active Directory. This integration allows the enforcement of granular Windows NTFS Access Control Lists (ACLs) for permission management, moving beyond simple Storage Account Key access.
For hybrid infrastructure, the scope extends to configuring Azure File Sync. Administrators deploy the Storage Sync Agent on on-premises Windows Servers and define Sync Groups in the Azure Portal. This configuration enables 'cloud tiering,' where frequently accessed data remains cached locally for low-latency performance, while older data is moved to the cloud to free up local space.
Finally, operational configuration includes enabling Soft Delete to recover from accidental deletions, scheduling Snapshots for backup resilience, and implementing Private Endpoints to ensure traffic between clients and the file share remains on the secure Microsoft backbone network rather than the public internet.
Comprehensive Guide: Configuring and Managing Azure File Shares for AZ-104
Why it is Important Azure File Shares are a cornerstone of the 'Implement and Manage Storage' objective in the AZ-104 exam. In enterprise environments, organizations are constanty looking to 'lift and shift' legacy applications to the cloud without rewriting code. Because Azure Files offers fully managed file shares accessible via the industry-standard SMB and NFS protocols, it is the go-to solution for replacing on-premises file servers, sharing data across virtual machines, and managing hybrid cloud storage via Azure File Sync.
What it is Azure Files is a fully managed cloud file system. Unlike blob storage (which is object storage designed for massive amounts of unstructured data), Azure Files provides a hierarchical file system (folders and files) that can be mounted concurrently by cloud or on-premises deployments of Windows, Linux, and macOS. It removes the need to manage file server VMs and infrastructure, operating strictly as a PaaS (Platform as a Service) offering within an Azure Storage Account.
How it works To implement Azure Files, you must understand the following architecture: 1. Storage Account: File shares reside inside a storage account. You must choose between Standard (GPv2) or Premium based on IOPS and latency requirements. 2. Protocols: SMB (Server Message Block): Standard for Windows and compatible with Linux/macOS. Uses port 445. NFS (Network File System): Used primarily by Linux clients. Requires a Premium storage account and only works via Private Endpoint or Public Endpoint with specific VNet restrictions. 3. Access Tiers: Premium: High performance using SSDs. Transaction Optimized: Heavy workloads, high transaction rates. Hot: General purpose file sharing. Cool: Archive data, rarely accessed. 4. Authentication: Access can be granted via the Storage Account Key (admin access) or Identity-based authentication (Azure Active Directory / Entra ID, or on-prem AD DS).
How to Answer Questions regarding Configure Azure File shares When facing scenario-based questions in the exam, follow this logic flow: 1. Identify the OS: If the scenario mentions Linux specifically requiring POSIX compliance, lean toward NFS shares. If it involves Windows or mixed environments, SMB is the answer. 2. Check the Connectivity: If a question describes a failure to mount a drive from on-premises, the answer is almost always related to ISP blocking Port 445 (SMB). 3. Analyze Access Requirements: If the question asks to secure access using individual user permissions (ACLs), you must select identity-based authentication (AD DS integration), as Storage Keys provide full admin access only. 4. Latency vs. Cost: If the scenario demands single-digit millisecond latency, you must configure a Premium FileShare.
Exam Tips: Answering Questions on Configure Azure File shares Tip 1: Snapshot Behavior Remember that file share snapshots are read-only copies of the share at a point in time. If a question asks how to recover a single corrupted file, you can copy it from a previous snapshot. If an administrator deletes the Share itself, the snapshots are also deleted (unless a lock or soft-delete is enabled).
Tip 2: Azure File Sync Many questions link File Shares to Azure File Sync. Know the components: Storage Sync Service: The top-level resource. Sync Group: Defines the topology. Registered Server: The on-prem server. Cloud Endpoint: The Azure File Share. Server Endpoint: The folder on the on-prem server. Cloud Tiering is a keyword. If the exam asks how to free up space on an on-prem server while keeping all data available in the cloud, Enable Cloud Tiering is the answer.
Tip 3: PowerShell Cmdlets Familiarize yourself with basic cmdlets. New-AzStorageShare is used to create the share. Get-AzStorageShare retrieves details. Questions may present a script and ask what is missing to mount the drive—usually ensuring the storage context or credentials are passed correctly.
Tip 4: Network Security Be aware that by default, storage accounts accept traffic from all networks. Exam questions often require you to configure the 'Firewalls and virtual networks' settings to 'Selected networks' or configure a Private Endpoint to secure the file share.
