- Azure Key Vault and encryption basics
AZ-900 Preparation Details
Time Required: 2-4 weeks for complete beginners
You can compress this into 10 days if you work full-time on it. Conversely, studying part-time over 6 weeks is reasonable for someone juggling work and family.
Study Approach:
- Watch Microsoft Learn modules (free, official)
- Review practice questions on azureprep.com
- Complete Azure fundamentals learning paths
- Skip hands-on labs (not required for AZ-900)
Why People Underestimate This Exam:
Despite being "fundamentals," AZ-900 surprises many test-takers with specificity. It's not enough to know "Azure has storage services." You need to understand when to use Blob Storage versus Azure Files versus Managed Disks. The exam tests comprehension, not just vocabulary.
Pass Rate Reality: Most people with disciplined preparation pass on the first attempt. The 70-75% industry pass rate reflects people who cram 3 days before testing.
The AZ-900 Value Proposition
AZ-900 provides legitimate value in specific situations:
- Career changers from non-technical roles: If you're transitioning from sales, HR, or management into cloud roles, AZ-900 establishes credibility and foundational understanding.
- Project managers and business analysts: These roles benefit from understanding what Azure can do, even without hands-on administration.
- Learning pathway preparation: Starting with AZ-900 before AZ-104 creates a gentler learning curve.
- Employer requirements: Some organizations require AZ-900 certification for hiring or promotions.
However, AZ-900 holds minimal weight in hiring decisions for technical roles. Technical hiring managers want to see AZ-104 or higher certifications that prove practical skills.
Understanding AZ-104: Azure Administrator
AZ-104 certifies practical Azure administration skills. This is where the career trajectory changes. AZ-104 directly impacts hiring prospects, salary negotiations, and job responsibilities.

AZ-104 Preparation Details
Time Required: 6-12 weeks for people with Azure exposure
This timeline assumes you're working full-time while studying. With dedicated study time, 4 weeks is achievable if you have infrastructure background.
Study Approach:
- Complete Microsoft Learn Administrator learning path (free, official)
- Practice hands-on labs in Azure portal (Microsoft Learn labs are free)
- Use azureprep.com practice tests repeatedly (aim for 80%+ scores)
- Deploy actual resources in Azure (free tier or low-cost subscriptions)
- Study real-world scenarios and architecture decisions
Why Hands-On Labs Are Critical:
Unlike AZ-900, you cannot pass AZ-104 on theory alone. The exam expects you to understand how services interact. Creating VMs, configuring NSGs, setting up storage accounts, and implementing backups solidifies this knowledge in ways videos and flashcards cannot.
Pass Rate Reality: The 55-65% pass rate reflects the exam's practical difficulty. People who watch videos but skip hands-on labs typically fail. Those who deploy actual resources and practice troubleshooting pass consistently.
The AZ-104 Career Impact
Passing AZ-104 creates measurable career benefits:
- Hiring: Azure Administrator positions require or strongly prefer this certification. LinkedIn data shows 8,000+ open positions specifically seeking AZ-104 certified professionals.
- Salary: Azure certified administrators earn 5-15% more than their non-certified counterparts, depending on geography and experience.
- Promotion: Internal promotions to cloud infrastructure roles often require this certification.
- Skills: You gain practical abilities directly applicable to job responsibilities immediately.
Who Should Start with AZ-900
Take AZ-900 first if you fit any of these profiles:
Completely New to Cloud Computing
You've never worked with AWS, Google Cloud, or Azure. You don't understand concepts like availability zones, managed services, or scaling. AZ-900 builds this vocabulary and mental model before tackling Azure specifics.
Non-Technical Background Entering Cloud Field
You're transitioning from sales, finance, operations, or other non-technical roles into cloud-adjacent positions. AZ-900 establishes credibility and provides context for more technical discussions.
Business Roles (Managers, Architects, Product Owners)
You need cloud literacy without deep technical implementation knowledge. AZ-900 covers what you need to understand business impact, cost analysis, and technology decisions.
Company Mandates AZ-900 First
Some organizations require junior team members to complete AZ-900 before tackling AZ-104. This policy ensures consistent foundational knowledge across teams.
Learning Preference: Gradual Progression
You learn best through gradual advancement. Jumping straight to AZ-104 feels overwhelming. Starting with AZ-900 builds confidence and creates momentum.
Who Should Skip AZ-900 and Go Straight to AZ-104
You can skip AZ-900 entirely if you meet these criteria:
Experienced Infrastructure Administrator
You manage on-premises servers, networks, storage, and security daily. The concepts translate directly to Azure. AZ-900 feels tediously basic. Your time is better spent learning Azure-specific implementations.
AWS or Google Cloud Certified
You understand cloud architecture, service models, and deployment options. You only need to learn Azure's approach and naming conventions. AZ-900 covers material you already know.
Professional with Cloud Experience
You've deployed resources in Azure as part of your job. You understand subscriptions, resource groups, VMs, and networking. You need to formalize this knowledge through AZ-104, not start from scratch with AZ-900.
Strong IT Foundation (Network+, Security+, MCSA)
CompTIA or Microsoft certifications prove foundational understanding. You're ready for AZ-104 technical depth immediately.
Significant Self-Study in Azure
You've completed Microsoft Learn modules on Azure services, deployed labs, and studied architecture. You don't need AZ-900 review. Move directly to AZ-104 to earn recognition for your skills.
The key factor: if you already understand cloud concepts, skip AZ-900 and invest those weeks into AZ-104 mastery.
The Typical Azure Certification Path
Most Azure professionals follow this progression:
Stage 1: AZ-900 (Optional - Skip if Experienced)
Foundation level. 2-4 weeks prep. Covers cloud concepts and Azure basics.
Stage 2: AZ-104 (Administrator)
Intermediate level. 6-12 weeks prep. Covers hands-on administration and practical skills. This is where careers accelerate.
Stage 3: AZ-305 (Solutions Architect)
Advanced level. 10-16 weeks prep. Requires AZ-104 knowledge. Covers architecture, design, and large-scale implementation decisions.
This three-tier structure makes sense because each builds on previous knowledge. However, the pathway isn't mandatory. Some people focus on specialty paths:
Security Path: AZ-104 > AZ-500 (Security Engineer)
Developer Path: AZ-204 (Developer Associate) skips administrator concepts
Data Path: AZ-104 > AZ-305 > DP-203 (Azure Data Engineer, Associate)
The most common path for career advancement remains: AZ-104 > AZ-305 > DP-203.
Can You Actually Skip AZ-900? The Reality
Yes, absolutely. Many experienced administrators skip AZ-900 and go directly to AZ-104 without difficulty. Here's what happens:
What You Miss (If You Skip):
- Structured review of cloud service model definitions
- Formal overview of Azure's global infrastructure
- Compliance and governance frameworks overview
Why This Doesn't Matter for Experienced Admins:
You learn these concepts through practical use. When you're configuring VNets and NSGs in AZ-104 labs, you understand the infrastructure. When you're implementing RBAC, you grasp governance. You pick up what AZ-900 teaches through context in AZ-104.
The Catch:
Some specific AZ-104 exam questions reference concepts emphasized in AZ-900 (like shared responsibility models or cloud deployment types). However, these questions comprise only 5-10% of the exam. Your hands-on experience compensates.
The Honest Assessment:
Skipping AZ-900 saves 2-4 weeks but requires either substantial existing Azure experience or willingness to pick up foundational concepts during AZ-104 prep. It's not impossible, but it's harder. The decision depends on your current knowledge depth.
