How difficult is the AZ-104 exam?

Honest verdict: AZ-104 is a legitimately demanding exam — the hardest of Microsoft's mainstream associate-level certifications for most candidates, and a completely different proposition from AZ-900. It does not ask whether you know what Azure services are called; it asks whether you can administer them. People who treat it as a reading exam fail it. People who have spent real time in an Azure tenant, or who deliberately build that time in a lab, find it challenging but fair.

The verdict up front

Microsoft scores AZ-104 on a 100–1,000 scale with 700 required to pass, and the questions are predominantly scenario-based: a situation is described, and you must choose the action an Azure administrator would actually take. Many items involve the portal, Azure CLI, or PowerShell context — screenshots, command choices, configuration sequences — so the exam quietly assumes tooling fluency. Add case studies with multiple linked questions, and you have an exam that measures working competence rather than familiarity.

The simplest way to feel its weight is the comparison everyone makes: AZ-900 teaches you the vocabulary of Azure — what a resource group is, what a service does. AZ-104 assumes that vocabulary on the first line of every question and then asks you to configure, secure, troubleshoot, and monitor the thing. It is the classic jump from vocabulary to operations, and it catches out a steady stream of candidates who passed AZ-900 easily and expected more of the same.

What actually makes AZ-104 hard

Breadth across five operational areas. The exam spans identity and governance (Microsoft Entra ID, RBAC, subscriptions, policies), storage, compute (VMs, containers, App Service), virtual networking, and monitoring and backup. Each area is examined at working depth. Networking and identity in particular reward candidates who have actually built VNets, NSGs, and role assignments rather than read summaries of them.

Hands-on assumption. Many questions are effectively asking "have you done this?" in disguise. The difference between the almost-right option and the right one is often a step in a procedure, a prerequisite, or a limitation you only learn by doing — such as which setting lives where, or what must exist before a feature can be enabled. Candidates also ask whether AZ-104 includes live labs or performance-based tasks — worth settling before you decide how to practise.

Case studies and item variety. Beyond case studies, expect drag-and-drop sequences, hotspot-style items, and questions where the same scenario continues across several screens. These formats reward methodical reading; rushing the scenario text is a common and expensive mistake.

Depth without warning. A topic that sounds simple — backups, say — is examined down to retention behaviour, vault configuration, and recovery details. The syllabus looks like five headings; the exam treats each heading as a job.

Where candidates actually lose the marks

Failed AZ-104 attempts tend to fail at predictable seams. Identity and access is the first: RBAC scope inheritance, the difference between Microsoft Entra roles and Azure roles, and conditional access behaviour are examined in combinations that punish anyone who has only read definitions. Networking is the second — NSG rule evaluation order, VNet peering behaviour, DNS, and load balancing choices inside scenarios where two answers both "work" but only one meets the stated constraint. Backup and monitoring form the quiet third seam: candidates deprioritise them as minor topics, then meet detailed questions on vault configuration, retention, and alert behaviour that they cannot reason out from first principles.

There is also a mechanical factor. Case study sections in Microsoft exams are typically presented as their own sections, and once you leave a section you cannot return to it — so the time you spend inside a case study has to be decisive. Candidates who treat the opening case study casually, expecting to revisit it later, discover the structure the expensive way. The same applies to sequencing items: an order that is almost right scores the same as one that is entirely wrong.

How it compares to neighbouring certifications

Within Microsoft's ladder it sits clearly above AZ-900 (fundamentals) and is generally considered a heavier lift than the more focused associate exams, because its surface area is so wide — AZ-500, for example, goes deeper on security but across a narrower field. Administrators arriving from AWS often compare it to the SysOps/associate tier: similar working level, but AZ-104 leans harder on identity and governance than many expect. The expert-level AZ-305 is a design exam and a different skill; AZ-104's difficulty is operational, not architectural.

Who finds it hard, and who finds it manageable

• Working Azure administrators with six months or more of tenant time usually find it manageable — their main work is filling the areas their job never touches.
• On-premises sysadmins moving to cloud have the concepts but must rebuild them in Azure's model; identity and networking mappings are where they stumble.
• Certification-first learners with no tenant experience find this one of the hardest associate exams anywhere, because so much of it is disguised experience.
• AZ-900 holders should expect a step change, not a sequel — the overlap is vocabulary, not level.

Preparation that actually moves the needle

Lab time is the single biggest variable. Use a free or sandbox tenant and perform the syllabus as tasks: create and scope RBAC assignments, build and peer VNets, configure backup and restore, deploy and troubleshoot. Read errors, break things, fix them. Pair that with scenario-style questions scored by domain, so you can see whether storage or networking is your real weakness, and practise reading case studies slowly and completely.

As a planning heuristic rather than a guarantee: administrators already working in Azure often prepare in four to eight weeks of focused part-time study, while candidates building cloud experience from scratch should plan on several months, most of it in the portal rather than in a book. Timed, domain-scored practice — including the free practice tests on Study4Pass — is most useful after lab work, when it can measure operational readiness instead of just recognition. Before you book, it also pays to check how much the AZ-104 exam costs and which languages it runs in and to keep an eye on the AZ-104 roadmap and any retirement plans and the AZ-104 retake policy if the first attempt does not go to plan.
