- A
A model that trusts all traffic within the corporate network boundary
Why wrong: Trusting internal network traffic is the traditional 'castle and moat' model — Zero Trust is the opposite approach.
- B
A model that verifies every access request regardless of network location
Zero Trust verifies identity, device health, and access context for every request, never trusting implicitly based on network location.
- C
A model that uses no security controls to maximize productivity
Why wrong: Zero Trust uses extensive security controls; 'zero' refers to implicit trust, not security controls.
- D
A model that allows only Microsoft-approved applications on Azure
Why wrong: Zero Trust is about continuous verification of identity and access, not restricting to Microsoft applications.
Quick Answer
The correct answer is a model that verifies every access request regardless of network location. This is because the zero trust security model operates on the principle of 'never trust, always verify,' meaning it treats every access attempt as a potential threat, requiring authentication, authorization, and encryption for each request—whether the user is inside the corporate network or connecting remotely. On the Microsoft Azure Fundamentals AZ-900 exam, this concept tests your understanding of modern security architecture, often appearing in questions that contrast zero trust with traditional perimeter-based security. A common trap is assuming that being on a corporate network implies trust, but zero trust eliminates that assumption entirely. Azure supports zero trust through services like Microsoft Entra ID for conditional access, Azure Policy for compliance enforcement, and Microsoft Defender for Cloud for continuous monitoring. Memory tip: think of zero trust as a bouncer who checks ID at every door, not just the front entrance.

Correct answer & explanation
A model that verifies every access request regardless of network location
The zero trust security model operates on the principle of 'never trust, always verify,' meaning every access request is authenticated, authorized, and encrypted regardless of the user's location or network. Azure supports zero trust through services like Azure Active Directory (now Microsoft Entra ID) for conditional access policies, Azure Policy for enforcing compliance, and Azure Security Center for continuous monitoring and threat detection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse zero trust with the traditional 'trust but verify' model (Option A) or assume it means no security at all (Option C), when in fact zero trust enforces strict verification for every request regardless of network location.
Detailed technical explanation
How to think about this question
Under the hood, zero trust relies on micro-segmentation, least-privilege access, and continuous validation of tokens (e.g., OAuth 2.0, SAML) rather than static network perimeters. In Azure, this is implemented via Azure AD Conditional Access policies that evaluate signals like user risk, device compliance, and location in real-time before granting access. A real-world scenario is a remote employee accessing a sensitive database—zero trust would require MFA and device health checks even if the employee is on a corporate VPN.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
