AZ-104 vs AZ-103: Breaking Down the New Microsoft Azure Administrator Requirements

The transition from AZ-103 to AZ-104 represented one of the most significant updates Microsoft made to its Azure Administrator certification track in recent years. For IT professionals actively working toward Azure certification or those already holding the older credential, understanding exactly what changed, what stayed the same, and what the update means for career planning is genuinely important information that shapes how they invest their study time and professional development efforts.

Microsoft does not update its certification exams casually. When the company retires one exam and launches a replacement, it signals a meaningful shift in how the organization views the skills and knowledge that Azure administrators need in current enterprise environments. The move from AZ-103 to AZ-104 was driven by real changes in the Azure platform itself, evolution in how organizations deploy and manage Azure resources, and feedback from the industry about which competencies matter most in day-to-day Azure administration work. Understanding those drivers helps candidates appreciate not just what changed on the exam but why those changes were made.

Historical Context Behind AZ-103

The AZ-103 exam was itself the product of a prior consolidation effort. Before AZ-103 existed, candidates pursuing the Azure Administrator Associate certification had to pass two separate exams, AZ-100 and AZ-101, which together covered the full scope of Azure administration knowledge. Microsoft consolidated those two exams into the single AZ-103 exam to create a more streamlined certification path that was easier for candidates to navigate and for employers to understand.

AZ-103 launched in 2019 and quickly became one of the most popular Azure certifications available. It covered the core administrative tasks that Azure administrators perform regularly, including managing subscriptions and resources, implementing and managing storage, deploying and managing virtual machines, configuring and managing virtual networks, and managing identities using Azure Active Directory. The exam was well-regarded for its practical focus and its alignment with real administrative work rather than theoretical concepts that rarely appear in production environments. Despite its popularity and solid reputation, Microsoft recognized that the Azure platform had evolved enough since AZ-103 was designed that a meaningful update was needed to keep the certification current and relevant.

When AZ-104 Officially Launched

Microsoft released the AZ-104 exam in April 2020, and AZ-103 was retired shortly thereafter. The transition was announced with enough advance notice to allow candidates who were already deep into their AZ-103 preparation to complete their certification before the old exam disappeared, and Microsoft provided clear guidance about how existing AZ-103 holders would be treated in the new certification framework. Professionals who had already earned the Azure Administrator Associate certification through AZ-103 retained their certification and were not required to retake any exam simply because the underlying exam changed.

The timing of the AZ-104 launch was significant because it coincided with a period of rapid Azure platform development. Microsoft had been releasing new services, updating existing ones, and changing how certain Azure features were configured and managed at a pace that made the AZ-103 content feel increasingly dated in some areas. The AZ-104 update gave Microsoft the opportunity to remove exam content covering features that had changed significantly or been deprecated, add content covering newer capabilities that had become important parts of an Azure administrator’s daily toolkit, and rebalance the weighting of different topic areas to better reflect how administrators actually spend their time in current Azure environments.

Core Structural Differences Identified

One of the most immediately noticeable differences between AZ-103 and AZ-104 is the restructuring of the exam objective domains and how content is weighted across them. AZ-103 organized its content around five primary skill areas with weightings that reflected the Azure platform as it existed in 2019. AZ-104 reorganized this content into a similar but meaningfully different set of domains with updated weightings that reflect current administrative realities.

The AZ-104 domain structure covers managing Azure identities and governance, implementing and managing storage, deploying and managing Azure compute resources, configuring and managing virtual networking, and monitoring and maintaining Azure resources. While these domains bear surface similarity to what AZ-103 covered, the content within each domain and the relative emphasis given to different topics shifted in ways that matter for preparation. Governance topics received significantly expanded coverage in AZ-104 compared to AZ-103, reflecting the growing importance of Azure Policy, role-based access control, resource locks, and management groups in how organizations manage their Azure environments at scale. Monitoring also received greater emphasis, acknowledging that observability and operational awareness have become core administrative responsibilities rather than supplementary concerns.

Identity Management Topic Evolution

Identity and access management saw some of the most substantial content evolution between AZ-103 and AZ-104. In AZ-103, Azure Active Directory topics were present but did not receive the depth of coverage that has become necessary given how central Azure AD has become to virtually every aspect of Azure administration. AZ-104 expanded the identity domain significantly to reflect the reality that modern Azure administrators spend considerable time managing users, groups, roles, and access policies across complex organizational structures.

AZ-104 added deeper coverage of Azure AD concepts including hybrid identity scenarios where on-premises Active Directory is synchronized with Azure AD, multi-factor authentication configuration and management, conditional access policies, and Azure AD roles versus Azure resource roles. The exam also expanded its coverage of role-based access control, expecting candidates to understand not just the basic mechanics of assigning built-in roles but also how to design RBAC structures that meet organizational requirements for least-privilege access, how to create custom roles when built-in options are insufficient, and how to audit and review role assignments across large Azure environments with many subscriptions and resource groups.

Governance and Compliance Additions

Governance was a relatively minor topic in AZ-103 but became a substantially more significant domain in AZ-104. This shift reflects a genuine change in how Azure administration is practiced in enterprise environments. In the early days of Azure adoption, many organizations focused primarily on getting workloads running in the cloud and treated governance as a secondary concern. As Azure deployments have matured and expanded, the need for structured governance frameworks that enforce organizational policies, control costs, maintain security standards, and ensure compliance with regulatory requirements has become a primary administrative responsibility.

AZ-104 covers Azure governance tools in much greater depth than AZ-103 did. Management groups, which allow organizations to apply policies and access controls across multiple subscriptions in a hierarchical structure, receive dedicated coverage that was largely absent from AZ-103. Azure Policy, which enables administrators to define rules that Azure resources must comply with and automatically enforce or audit those rules across the environment, is covered extensively in AZ-104 with expectations that candidates understand how to create policy definitions, assign policies at different scopes, interpret compliance reports, and remediate non-compliant resources. Resource locks and tagging strategies for cost management and resource organization also appear with greater depth in AZ-104.

Virtual Machine Management Changes

Virtual machine management has been a central topic in both AZ-103 and AZ-104, but the specific content and emphasis evolved meaningfully between the two exams. AZ-103 covered virtual machine deployment, configuration, and management in ways that reflected how administrators worked with VMs in the Azure portal and through PowerShell and Azure CLI commands. AZ-104 retained this foundational coverage while adding updated content that reflects newer VM management capabilities and changed some of the specific tasks and scenarios that the exam tests.

AZ-104 places greater emphasis on Azure VM Scale Sets and how they are used to build scalable application tiers that can automatically adjust the number of VM instances based on demand or schedules. The exam also gives more attention to VM availability configurations including availability sets and availability zones, which protect applications against hardware failures and datacenter-level outages respectively. Azure Dedicated Hosts, which allow organizations to run VMs on physical servers dedicated exclusively to their use for compliance and licensing reasons, appeared in AZ-104 in a way that reflected their growing adoption in enterprise environments where regulatory requirements demand physical isolation of workloads.

Storage Configuration Topic Updates

Storage administration is another area where the content evolved noticeably from AZ-103 to AZ-104. Both exams cover Azure Storage accounts and the various storage services within them, but the specific features, configuration options, and management scenarios that are tested changed to reflect updates in the Azure Storage platform. AZ-104 candidates need to understand storage account types and their appropriate use cases, replication options and how to choose between them based on durability and availability requirements, and access control mechanisms for protecting storage data.

One area where AZ-104 deepened its storage coverage is Azure File Sync, which allows organizations to extend on-premises Windows file servers to Azure by synchronizing file shares and optionally tiering infrequently accessed files to cloud storage. This hybrid storage capability became increasingly important to organizations managing the transition from purely on-premises environments to cloud or hybrid architectures, and AZ-104 reflects that importance with more substantial coverage than AZ-103 provided. Storage lifecycle management policies, which automatically move blob data between access tiers based on age or access patterns to optimize storage costs, also received expanded attention in AZ-104 as cost optimization became a more central administrative concern.

Networking Content Refinements

Networking is one of the most technically complex areas of Azure administration and has always been a significant portion of both AZ-103 and AZ-104. The networking content in AZ-104 covers virtual networks, subnets, network security groups, application security groups, Azure DNS, VNet peering, VPN gateways, ExpressRoute, Azure Load Balancer, Application Gateway, and Azure Bastion, among other topics. While much of this content existed in AZ-103, the depth and specific scenarios tested in AZ-104 reflect the growing complexity of Azure networking in multi-region and hybrid enterprise deployments.

AZ-104 gives notable additional attention to network routing and how administrators control traffic flow between subnets, virtual networks, and on-premises networks using route tables and user-defined routes. The exam also covers network monitoring tools more thoroughly, including Network Watcher and its suite of diagnostic capabilities that help administrators troubleshoot connectivity problems and verify that traffic is flowing as intended through complex network topologies. Azure Firewall, which provides centralized network security policy enforcement, received expanded coverage in AZ-104 compared to what AZ-103 covered, reflecting its growing adoption as organizations seek more sophisticated network security controls than network security groups alone can provide.

Monitoring Domain Expansion

Monitoring and maintaining Azure resources is an area where AZ-104 made some of its most substantial additions compared to AZ-103. The AZ-103 exam touched on monitoring topics but treated them somewhat lightly relative to their actual importance in day-to-day Azure administration. AZ-104 elevated monitoring to a more prominent position in the exam content, acknowledging that keeping Azure environments healthy, performant, and cost-effective requires ongoing attention to metrics, logs, alerts, and backup configurations.

AZ-104 expects candidates to have solid working knowledge of Azure Monitor and how it collects, stores, and allows analysis of metrics and log data from Azure resources. Log Analytics workspaces, which serve as the central repository for log data in Azure Monitor, receive specific coverage including how to configure diagnostic settings to route resource logs to a workspace, how to write basic queries using the Kusto Query Language to retrieve and analyze log data, and how to create alert rules that notify administrators when specific conditions are detected. Azure Backup and Azure Site Recovery also appear in AZ-104 with the expectation that candidates understand how to configure backup policies, perform recovery operations, and set up replication for business continuity purposes.

Preparation Approach Differences

For candidates who studied for AZ-103 before its retirement and are now preparing for AZ-104, the preparation approach needs to account for the specific areas where the content evolved rather than treating the two exams as equivalent. Candidates with AZ-103 study experience can build on that foundation by focusing additional attention on the governance and policy topics that AZ-104 emphasizes more heavily, deepening their knowledge of Azure Monitor and the operational maintenance topics that received expanded coverage, and updating their understanding of any specific services or features that changed significantly between the two exam versions.

For candidates approaching AZ-104 without prior AZ-103 study experience, the preparation should be built around the current AZ-104 exam objectives published by Microsoft rather than any older study materials that were created for AZ-103. Some older study books, video courses, and practice exams were originally created for AZ-103 and may not fully reflect the AZ-104 content or the updated Azure features that the exam now covers. Using current, AZ-104-specific preparation materials ensures that your study time aligns with what will actually be tested and prevents you from spending time on deprecated content that no longer appears on the exam.

Value for Existing Certificate Holders

Professionals who earned the Azure Administrator Associate certification through AZ-103 naturally wonder what the transition to AZ-104 means for the ongoing value of their existing credential. The reassuring answer is that Microsoft handled the transition in a way that did not invalidate or diminish certifications earned through AZ-103. Professionals who passed AZ-103 and earned the Azure Administrator Associate credential retained that certification and continued to be recognized as Azure Administrator Associates without any additional exam requirements.

However, Microsoft certifications in the role-based framework do have renewal requirements. Rather than expiring entirely and requiring a full retake of the certification exam, Microsoft moved to a renewal model where certified professionals must complete a free online renewal assessment through Microsoft Learn before their certification expires to demonstrate that their knowledge remains current. This renewal process means that AZ-103 holders who want to maintain an active, current certification status need to stay engaged with the evolving Azure platform and pass the renewal assessment periodically. The renewal questions reflect current exam content rather than the specific exam version used to earn the original certification, which means AZ-103 holders effectively need to know current AZ-104 content to successfully renew their credential.

Conclusion

The evolution from AZ-103 to AZ-104 offers lessons that extend beyond the specific content differences between the two exams. It illustrates something fundamental about how cloud certifications work in an era of rapid platform development. Cloud platforms like Azure change continuously, adding new services, updating existing ones, changing how features are configured and managed, and shifting the relative importance of different administrative competencies as the platform matures and organizational adoption patterns evolve. Certifications that do not keep pace with those changes become progressively less valuable as markers of current, relevant expertise.

Microsoft’s decision to update the Azure Administrator exam reflects a commitment to keeping its certification program aligned with what Azure administrators actually need to know to do their jobs effectively in current enterprise environments. The expanded governance content in AZ-104 reflects the maturation of Azure deployments from experimental to production-critical. The deepened monitoring coverage reflects growing organizational recognition that operational visibility is not optional. The updated identity and access management content reflects how central Azure AD has become to every aspect of cloud administration. Each of these shifts in exam content mirrors a genuine shift in the Azure platform and in how organizations use it.

For professionals building careers around Azure expertise, the lesson is that certification is not a one-time achievement but an ongoing commitment to staying current with a platform that will continue to evolve throughout their careers. The transition from AZ-103 to AZ-104 was not a disruption to avoid but an opportunity to update knowledge, fill gaps, and ensure that certified expertise remains genuinely reflective of current Azure capabilities and best practices. Professionals who embrace that continuous learning mindset will find that Microsoft’s regular exam updates keep their certifications meaningful and their skills relevant in a job market that consistently rewards demonstrated, current, and verified Azure expertise with strong career opportunities and competitive compensation.

The AZ-104 exam, understood in the context of its evolution from AZ-103, represents Microsoft’s best current definition of what it means to be a competent Azure administrator. Preparing for it thoroughly, earning it, and maintaining it through regular renewal is a worthwhile professional investment that pays returns across many years of an Azure-focused career.
