Earning the Microsoft Azure Administrator (AZ-104) certification is a major milestone for IT professionals. It validates your ability to deploy, manage, and monitor Azure environments, making it one of the most highly sought-after cloud credentials in the industry. However, it is also notoriously difficult.

Many candidates walk into the testing center feeling fully prepared, only to fail by a narrow margin. Why? Because passing this exam requires more than just knowing Azure concepts; it requires understanding how Microsoft tests those concepts.

If you are wondering, what are common mistakes on the AZ-104 exam? We have synthesized data from top industry experts, recent exam takers, and certification forums to bring you the definitive list of pitfalls to avoid. Before you begin, ensure you have reviewed the AZ-104 certification requirements to verify your readiness.

Top 5 Pitfalls to Avoid

Data from recent exam-takers shows these five errors are the leading causes of failing the AZ-104.

1. The MS Learn Trap

Using the open-book feature to “learn” concepts during the test consumes critical time, ensuring you won’t finish.

2. Case Study Blindness

Treating case studies as normal questions. They are locked; if you mismanage time here, you cannot go back.

3. Neglecting Labs

Attempting to pass with theory alone. You must have hands-on experience in the Azure Portal.

4. The “No-Return” Panic

Failing to prepare mentally for the “Yes/No” series where you cannot review previous answers.

5. Under-preparing Networking

Networking is the heaviest weight in the exam. Skip it, and you likely fail.

What are Common Mistakes on The AZ-104 Exam?

By understanding these structural and technical traps, you can adjust your study plan and walk into exam day with confidence. Let’s break down each mistake in detail and explore exactly how to overcome them.

Mistake 1: The “Open Book” MS Learn Time Trap

In recent updates, Microsoft introduced the ability to access Microsoft Learn directly from the exam interface. While this sounds like an incredible lifeline, it is actually the number one reason candidates run out of time.

The Mistake:

Candidates assume that because the exam is “open book,” they do not need to memorize certain concepts. During the exam, they encounter a complex question about Azure Kubernetes Service (AKS) or Azure File Sync, and they spend 5 to 7 minutes frantically clicking through Microsoft Learn trying to teach themselves the concept on the fly.

With approximately 50 questions and 120 minutes to complete the test, you have roughly 2 to 2.5 minutes per question. If you spend 7 minutes reading documentation, you are mathematically guaranteeing you won’t finish the exam.

The Solution:

Treat Microsoft Learn strictly as a syntax and SKU dictionary, not a textbook.

• Do use it for: Checking specific Azure Virtual Machine SKUs, verifying a PowerShell cmdlet syntax (New-AzVM vs Set-AzVM), or double-checking built-in Entra ID Role-Based Access Control (RBAC) permissions.
• Don’t use it for: Trying to understand how routing tables work or learning the architecture of a hub-and-spoke network.
• Pro Tip: Practice using the search function efficiently before exam day. Always use quotation marks for multi-word searches (e.g., "Standard Load Balancer limitations") to immediately filter the exact documentation you need.

Mistake 2: Mishandling the Case Study Sections

The AZ-104 exam features at least one, sometimes two, comprehensive case studies. These scenarios present you with a fictional company, its current IT environment, its planned Azure migration, and a list of business and technical requirements.

The Mistake:

There are two massive errors candidates make here. First, they do not realize that case studies are isolated and locked. If a case study appears at the beginning of the exam, you cannot skip it and come back later. If it appears at the end, and you spent 115 minutes on the multiple-choice questions, you will have 5 minutes to read an A4-sized wall of text and answer 5-6 complex questions.

Second, candidates waste 10 minutes reading the entire background of the fictional company before looking at the questions.

The Solution:

• Reverse Engineer the Case Study: Always read the questions first. Once you know what the question is asking (e.g., “Which storage solution meets the compliance requirements for Department X?”), you can skim the massive text specifically looking for “Department X” and “Compliance.” You will find that 60% of the case study text is irrelevant fluff designed to distract you.
• Time Allocation: Consciously reserve at least 20-25 minutes of your total exam time specifically for case studies.

Mistake 3: Skipping Hands-On Labs for Pure Theory

The AZ-104 is a role-based certification. It is designed to prove that you can sit down at a desk and administer an Azure environment on day one.

The Mistake:

Many candidates read the official Microsoft documentation, watch a 10-hour video course, and assume they are ready. They memorize what a Network Security Group (NSG) is, but they have never actually provisioned one in the Azure Portal. When the exam asks a highly specific question about where to click in the portal to configure a peering connection, or how a resource lock interacts with inherited tags, theory alone will fail you.

The Solution:

Your exam preparation must be at least 50% hands-on practice.

• Utilize the free sandbox environments provided in the Microsoft Learn AZ-104 path.
• Set up a free Azure account and physically build the architectures you study.
• Deploy a Virtual Machine, configure a VNet, set up peering, and assign RBAC roles to a dummy user.
• Intentionally break your configurations (e.g., block port 3389) and try to troubleshoot why you cannot RDP into your VM. This real-world troubleshooting is exactly what the exam tests. If you are unsure of your current level, checking how many hours to study for AZ-104 can help you structure your labs.

Mistake 4: Panicking During “No-Return” Question Sets

Beyond the standard multiple-choice and case study questions, the AZ-104 features a unique question format that catches many off guard.

The Mistake:

You will be presented with a scenario and a proposed solution. The question asks, “Does this solution meet the goal? Yes or No.” Once you answer this question and click “Next,” you can never go back to it. You cannot mark it for review. Candidates often realize on the third variation of the question that they answered the first one incorrectly. This leads to panic, tilting their focus for the rest of the exam.

The Solution:

Accept that these questions are designed to test your definitive knowledge of a specific feature.

• Read the scenario carefully. Microsoft will present the exact same scenario 3 or 4 times in a row, changing only the proposed solution.
• Evaluate the solution entirely on its own merits.
• If you realize you made a mistake on a previous question, let it go immediately. The AZ-104 uses a scaled scoring system (out of 1000, where 700 is passing). You do not need to be perfect; you just need to demonstrate overall competency.

Mistake 5: Underestimating Azure Networking & Identity

The AZ-104 Exam Skills Outline clearly defines the weighting of each domain. Despite this, candidates routinely misallocate their study time.

The Mistake:

Candidates spend weeks studying basic compute (Virtual Machines) and gloss over networking because it is technically dense. Virtual networking is widely considered the hardest part of the AZ-104.

The Solution:

Front-load your studying with Entra ID (formerly Azure AD) and Virtual Networking. You must understand subnetting, how traffic flows between VNets, VPN gateways, and how NSG rules evaluate traffic. If you do not have a strong grasp of networking, you will struggle to pass, as networking concepts bleed into compute and storage scenarios.

Mistake 6: Memorizing Practice Tests Without Understanding

Taking practice exams is a vital part of exam preparation. However, how you use those practice exams dictates your success.

The Mistake:

Candidates take a practice test, score a 60%, and then retake the exact same test until they score a 95%. They aren’t learning the Azure platform; they are just memorizing that the answer to question 12 is “Standard Load Balancer.” On the actual exam, Microsoft will present a nearly identical scenario, but change one keyword (e.g., from “regional” to “global”), which completely changes the correct answer to “Azure Front Door.”

The Solution:

When utilizing mock exams and practice tests, your goal should be to understand the why. When you get a question wrong, dig into the documentation to understand why your answer was incorrect, and why the correct answer is the right choice.

Frequently Asked Questions (AZ-104 Exam)

1. How long should I study for the AZ-104?

For someone with baseline IT knowledge, a structured study plan of 4 to 8 weeks (studying 10-15 hours a week) is typically sufficient. If you are entirely new to cloud computing, consider taking the AZ-900 (Azure Fundamentals) first, and allocate 8 to 12 weeks for the AZ-104. You can review the AZ-104 certification path to see how it fits into your career growth.

2. Can I use Microsoft Learn during the AZ-104 exam?

Yes. The AZ-104 allows access to Microsoft Learn via a button in the exam interface. However, the timer does not stop while you browse. You must use it sparingly for quick syntax lookups, not deep reading.

3. What is a passing score for the AZ-104?

You need a score of 700 out of 1000 to pass. Because questions are weighted differently based on difficulty, 700 does not strictly mean 70%.

4. Are there labs in the actual AZ-104 exam?

Historically, Microsoft has rotated live hands-on labs in and out of the AZ-104. As of recent testing formats, you are more likely to see heavy case studies and scenario-based multiple-choice questions rather than a live portal environment, but you must be prepared for both.

5. Which topic is the hardest on the AZ-104?

Most candidates cite “Configure and manage virtual networking” as the most difficult domain. It requires a deep understanding of routing, IP addressing, Network Security Groups, and connectivity services like VPN Gateways and ExpressRoute.

6. Can I skip a question and come back to it?

For standard multiple-choice questions, yes, you can mark them for review and return to them at the end of the section. However, you cannot return to questions in the “Yes/No” scenario blocks, nor can you leave a Case Study section and return to it later.

7. How many questions are on the AZ-104?

The exam typically contains between 45 and 60 questions, depending on the number of case studies and unscored beta questions included in your specific test form.

8. What happens if I fail the AZ-104?

If you fail on your first attempt, you must wait 24 hours before you can retake the exam. After completing your AZ-104 certification registration, ensure you have a retake plan in place.
