This article provides a comprehensive deep dive into the key skills measured in the AZ-104 exam, breaking down each domain to give you a clear roadmap for what you need to know to succeed.

Manage Azure Identities and Governance (15-20%)

Before you can build anything in Azure, you must first establish a secure and well-governed foundation. This domain is all about identity, access, and control—ensuring the right people have the right access to the right resources, and that organizational standards are enforced across the board.

Key Competencies:

Azure Active Directory (Azure AD): This is the heart of identity management in Azure. As an administrator, you'll need to be proficient in managing users, groups, and device identities within Azure AD. This includes creating and configuring user accounts, managing group memberships for streamlined permissions, and integrating on-premises Active Directory with Azure AD using Azure AD Connect.
Role-Based Access Control (RBAC): The principle of least privilege is paramount in the cloud. RBAC is Azure's mechanism for enforcing this. You must understand how to assign built-in roles like Owner, Contributor, and Reader at different scopes (management groups, subscriptions, resource groups, and individual resources). You should also know when and how to create custom RBAC roles to meet specific security requirements.
Subscription and Governance Management: Effective administration involves more than just technical tasks; it requires strong governance. This includes managing Azure subscriptions, implementing cost management practices by analyzing usage and setting budgets, and organizing resources logically using a hierarchy of management groups, subscriptions, and resource groups.
Azure Policy: To ensure compliance and consistency, administrators use Azure Policy. You’ll need to know how to create and assign policies to enforce rules, such as restricting which regions resources can be deployed to, enforcing specific VM SKUs, or ensuring all resources have necessary tags for cost tracking.

Implement and Manage Storage (15-20%)

Data is the lifeblood of any modern application, and how you store it is critical for performance, security, and cost-effectiveness. This domain covers the wide array of storage solutions Azure offers and how to manage them efficiently.

Key Competencies:

Storage Accounts: The fundamental building block for Azure Storage. You must understand how to create and configure storage accounts, including the differences between account types (like General-purpose v2 and BlockBlobStorage) and performance tiers (Standard vs. Premium). Replication strategies—such as Locally-Redundant Storage (LRS), Geo-Redundant Storage (GRS), and Zone-Redundant Storage (ZRS)—are also crucial concepts for ensuring data durability and availability.
Azure Blob Storage: This service is optimized for storing massive amounts of unstructured data, such as images, documents, and videos. A key skill is managing data lifecycle policies to automatically move blobs between access tiers (Hot, Cool, and Archive) to optimize costs.
Azure Files: For applications that require a shared file system, Azure Files provides fully managed file shares accessible via the industry-standard Server Message Block (SMB) protocol. You’ll need to know how to create an Azure File share, map it to a Windows or Linux VM, and configure access permissions.
Storage Security: Securing data at rest and in transit is non-negotiable. You must be able to manage access keys, create and use Shared Access Signatures (SAS) tokens for delegated access, and configure network access to storage accounts using firewalls and virtual network service endpoints.

Deploy and Manage Azure Compute Resources (20-25%)

This is the core of infrastructure-as-a-service (IaaS) and platform-as-a-service (PaaS). The compute domain focuses on the virtual machines, containers, and web apps that run your workloads. As an administrator, your job is to deploy, configure, and maintain these resources to ensure they are available, scalable, and performant.

Key Competencies:

Virtual Machines (VMs): The workhorse of Azure compute. You will be tested on your ability to create and configure both Windows and Linux VMs. This includes choosing the right VM size, configuring networking and storage, and understanding high-availability options like Availability Sets and Availability Zones. You also need to know how to automate VM deployments using Azure Resource Manager (ARM) templates and manage VM scalability with Virtual Machine Scale Sets.
Containers: While deep Kubernetes expertise is reserved for other certifications, an Azure Administrator should have a foundational understanding of containers. You'll need to know how to deploy a simple containerized application using Azure Container Instances (ACI), which offers a serverless way to run containers without managing underlying infrastructure.
Azure App Service: For hosting web applications and APIs, Azure App Service provides a powerful PaaS solution. Your responsibilities include creating App Service Plans (which define the underlying compute resources), deploying a web app, configuring deployment slots for blue-green deployments, and setting up custom domains and SSL certificates.

Configure and Manage Virtual Networking (25-30%)

Often considered the most challenging and heavily weighted domain of the AZ-104 exam, virtual networking is the glue that connects and secures all of your Azure resources. A deep understanding of networking principles is essential for any successful Azure Administrator.

Key Competencies:

Virtual Networks (VNets) and Subnets: You must be an expert in creating and configuring VNets, planning IP address spaces, and segmenting the network into subnets for organization and security.
Network Security: Securing traffic flow is critical. This involves implementing Network Security Groups (NSGs) to filter inbound and outbound traffic to and from Azure resources. You should be comfortable creating rules based on protocol, port, and source/destination IP addresses.
Azure DNS: Administrators are responsible for managing public and private DNS zones within Azure. This includes creating A records, CNAMEs, and other DNS records to resolve domain names to your services.
Connectivity: You’ll need to know how to connect VNets using VNet peering and how to establish hybrid connectivity between your on-premises network and Azure using VPN Gateways.
Traffic Management: To build resilient and scalable applications, you need to manage how traffic is distributed. This involves implementing and configuring Azure Load Balancer for distributing traffic within a VNet and Azure Application Gateway for advanced Layer 7 load balancing for web traffic.

Monitor and Back Up Azure Resources (10-15%)

Deploying resources is only half the battle. A proactive administrator must continuously monitor the health and performance of the environment and ensure that a robust backup and recovery plan is in place to protect against data loss and outages.

Key Competencies:

Azure Monitor: This is Azure’s unified monitoring solution. You need to know how to collect and analyze metrics and logs from various Azure resources. A key skill is creating alerts that trigger notifications or automated actions (via Action Groups) when performance thresholds are crossed or specific events occur.
Log Analytics: To perform deep troubleshooting and analysis, you'll use a Log Analytics workspace. This requires a basic understanding of the Kusto Query Language (KQL) to query the collected log data and gain insights into application performance and security events.
Azure Backup: Protecting your data is critical. You must be able to implement backup and recovery solutions using the Azure Backup service. This includes creating a Recovery Services Vault, defining backup policies, and performing restore operations for VMs, Azure Files, and on-premises workloads.
