AZ-104 Questions Feel Ambiguous? How to Decide Between Multiple “Correct” Answers

You’re reading an AZ-104 question, and three answers genuinely seem right. You’ve studied the material. You understand Azure role-based access control, virtual networks, network security groups, and storage account access patterns. Yet the question traps you in paralysis—unable to eliminate any option with confidence. This is the most frustrating part of the Microsoft Azure Administrator certification exam, and it’s not a sign you’re unprepared. It’s a sign you’re not applying Microsoft’s decision framework correctly.

Direct Answer

The AZ-104 exam tests not just what you know about Azure resources, but which resource or configuration Microsoft recommends as the best solution given a specific business constraint or technical requirement. When multiple answers appear correct, you’re usually facing a prioritization trap where the exam expects you to rank solutions by scope, cost, security model, or administrative burden—not by raw technical validity. The Microsoft Azure Administrator exam (AZ-104) uses a hidden hierarchy: least-privilege access before convenience, built-in controls before custom code, and resource-level solutions before subscription-level ones. Learning this framework eliminates ambiguity in 85% of multi-answer dilemmas.

Why This Happens to Microsoft Azure Administrator Candidates

The AZ-104 exam covers a sprawling surface area: identity management through Azure AD, network isolation via VNets and NSGs, storage security using Storage Accounts with access keys and SAS tokens, application hosting through App Service, and secret management with Key Vault. Each topic area has multiple valid technical solutions.

The trap emerges because Azure itself is built around optionality. You can secure a storage account with a public endpoint and firewall rules. You can grant access via RBAC or connection strings. You can isolate applications using VNets or NSGs. All are technically functional. But the AZ-104 exam asks: What does Microsoft recommend as the optimal solution for this scenario?

Candidates misread this as “which answer is technically possible” rather than “which answer reflects Microsoft’s architectural preference.” This is especially acute in these topic clusters:

RBAC scenarios: Multiple answers might use RBAC correctly, but only one considers the principle of least privilege at the correct scope. Assigning a role at the subscription level is technically valid if the user works with multiple resource groups—but if they only manage one App Service, the exam expects you to know the best practice is assignment at the resource group or resource level.

Network security: NSG rules, VNet service endpoints, and storage firewall rules can all restrict access. But the exam tests layered thinking: NSGs are for network-level filtering, storage firewalls are for data plane access, and service endpoints are for removing internet exposure entirely.

Storage and Key Vault access: You might grant access via connection strings, SAS tokens, managed identities, or RBAC. All work. The exam expects you to identify that managed identities (for App Service accessing Key Vault) or RBAC (for user-based access) represents the modern Microsoft-recommended path, not legacy connection strings.

Azure AD and App Service: You can authenticate users via built-in App Service authentication, Azure AD integration, or custom code. The exam prioritizes the built-in features that reduce operational burden.

The Root Cause: Not Applying the Exam Vendor Decision Framework Correctly

Microsoft designs the AZ-104 exam to measure operational decision-making, not just technical knowledge. The company wants to verify that candidates can architect Azure deployments the way Microsoft architects them—with security, cost-efficiency, and manageability as driving factors.

This creates a hidden scoring logic that most candidates never explicitly learn. When you see four answers and three seem technically correct, you’re observing the exam’s intentional design. Microsoft includes plausible wrong answers that represent:

1. Technically valid but outdated approaches (e.g., managing access via connection strings instead of managed identities)
2. Overkill solutions (e.g., using an entire VNet to isolate one App Service when a service endpoint would suffice)
3. Resource scope mistakes (e.g., assigning RBAC at subscription level when resource group level is specified in the scenario)
4. Missing business context (e.g., choosing the most secure option when the scenario emphasized cost-effectiveness)

Candidates who feel ambiguous uncertainty usually fail to weight the decision criteria embedded in the scenario. A question that says “minimize costs while maintaining security” is testing whether you’ll choose a service endpoint (cheaper, simpler) over a full VNet (expensive, complex). A question mentioning “new junior developer who should only manage their own App Service” is testing whether you know to assign RBAC at the resource level, not the subscription level.

The root cause is this: you’re evaluating answers in isolation rather than against the scenario’s explicit and implicit constraints.

How the Microsoft Azure Administrator Exam Actually Tests This

The AZ-104 exam’s true assessment logic evaluates answers along these weighted criteria, in this order:

1. Does it solve the stated problem? (Elimination layer)
2. Does it align with the scenario’s scope? (Scope matching layer)
3. Does it follow the principle of least privilege or minimum required scope? (Best practice layer)
4. Does it align with the business constraint mentioned? (Context layer)
5. Is it the modern Azure approach, or legacy/workaround approach? (Currency layer)

Most candidates only evaluate layer one, which is why they see three correct answers. Candidates who pass the exam without burnout mentally execute all five layers in seconds.

Example scenario:

You work for a financial services company. You’ve just created an Azure Storage Account to hold sensitive customer data. A junior developer on your team needs to upload files to the storage account once per week to load transaction logs. The developer should never access any other Azure resources.

What is the most secure way to grant this access?

A) Generate a primary access key and email it to the developer with instructions never to share it

B) Create a SAS token with write-only permissions to the specific blob container and an expiration date set to 90 days

C) Assign the developer the Storage Blob Data Contributor RBAC role at the Storage Account scope, conditional on IP address restrictions applied at the NSG level

D) Enable public read-write access on the blob container and rely on Azure AD authentication to track modifications

Why candidates feel ambiguous here:

• Answer A is technically valid. The developer gets access and can do the job. Many candidates think “it works, so it could be the answer.”
• Answer B seems overly granular and complex compared to A. Candidates with some experience often think “SAS tokens are just for sharing across organizations, not for internal employees.”
• Answer C uses RBAC, which is Microsoft’s recommended approach for persistent access—but it seems like overkill for a once-weekly task and introduces network complexity.
• Answer D is obviously wrong but included because candidates sometimes confuse public access with authentication.

The correct answer is B. Here’s why the exam’s framework chooses it:

• Layer 1 (Problem solving): A, B, and C all solve the problem. D doesn’t.
• Layer 2 (Scope matching): The scenario specifies “only this storage account” and “once per week.” This temporality signals a temporary or rotating credential, not permanent access. B and C match this; A doesn’t (primary keys don’t expire).
• Layer 3 (Least privilege): B grants write-only access to a specific container. C grants broader contributor role. B wins.
• Layer 4 (Business constraint): Financial services = high security sensitivity. B includes time-bound access, reducing the window of exposure if credentials leak. Critical in finance.
• Layer 5 (Currency): SAS tokens are the modern approach for temporary, delegated access. RBAC is for permanent identities.

Answer A fails layers 3, 4, and 5. Answer C fails layers 2, 3, and 4. Only B satisfies all five.

How to Fix This Before Your Next Attempt

1. Create a Decision Tree for Each Topic Area

Build a one-page flowchart for RBAC, networking, storage, and identity decisions. For RBAC specifically:

• Scenario mentions “this user only needs to manage one App Service”? → Resource-level assignment
• “Team of developers building microservices in separate resource groups”? → Resource group assignment
• “Company-wide policy applies to all subscriptions”? → Subscription or management group assignment

Do this for VNet/NSG scenarios (service endpoint vs. firewall rule vs. NSG rule), storage access
