Quick Answer
The answer is endpoints, as it is one of the six foundational pillars of Microsoft’s Zero Trust model. This model explicitly treats endpoints—such as devices, workstations, and mobile phones—as critical assets that must be continuously validated for health and compliance before granting access, enforcing least-privilege policies regardless of network location. On the Microsoft Cybersecurity Architect exam, this concept tests your understanding of the Zero Trust model components, often appearing in scenario-based questions where you must identify which pillars apply to a given security requirement. A common trap is confusing “data” with “endpoints” because both are pillars, but remember that endpoints focus on device-level control and signal evaluation, while data deals with encryption and labeling. To lock this in, use the mnemonic “I DEAN” for the six pillars: Identities, Devices (endpoints), Endpoints (redundant but helpful), Apps, Network, and Data.
This SC-100 practice question tests your understanding of design solutions that align with security best practices and priorities. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE are components of Microsoft's Zero Trust model?
Data
Protect data at rest, in transit, and in use.
Assume breach
Why wrong: A guiding principle, not a component.
Microsoft Defender for Cloud
Why wrong: A tool, not a Zero Trust component.
Identities
Verify explicitly, least privilege.
Endpoints
Devices accessing resources.

Correct answer & explanation
Data
Option A is correct because data is one of the six foundational pillars of Microsoft's Zero Trust model (identities, endpoints, data, apps, infrastructure, and network). The Zero Trust model explicitly treats data as a critical asset that must be protected regardless of location, using encryption, labeling, and Data Loss Prevention (DLP) policies to enforce least-privilege access and continuous validation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates confuse the Zero Trust guiding principles (like 'Assume breach') with the architectural components (identities, endpoints, data, apps, infrastructure, network), leading them to select 'Assume breach' as a component rather than a principle.
Detailed technical explanation
Under the hood, Microsoft's Zero Trust model maps each component to specific Azure AD Conditional Access policies, Microsoft Intune compliance rules, and Microsoft Purview sensitivity labels. For example, the 'data' component relies on Azure Information Protection (AIP) to classify and label files, with DLP policies enforced via Microsoft 365 compliance center, ensuring that access is granted only after real-time risk evaluation.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.

Same concept, more angles
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Which TWO Microsoft security solutions should be integrated to provide a comprehensive Zero Trust architecture that includes identity protection, endpoint detection, and response? (Select exactly two correct options.)
mediumWhy B: Microsoft Defender XDR (B) is correct because it provides unified endpoint detection and response (EDR) across devices, email, and identities, integrating signals from Microsoft Defender for Endpoint, Defender for Office 365, and Defender for Identity. Microsoft Entra ID (C) is correct because it delivers identity protection through Conditional Access, risk-based policies, and identity governance, forming the identity pillar of a Zero Trust architecture. Together, they cover identity protection and endpoint detection/response, two core Zero Trust components.
