The answer is Microsoft Entra Internet Access, Conditional Access, and Intune compliance. These three components form the foundation of a Zero Trust network architecture because they enforce the core principle of "never trust, always verify" at the identity, device, and network layers. Entra Internet Access acts as a secure internet breakout, replacing traditional VPNs by applying granular access policies directly to cloud traffic, while Conditional Access evaluates user and session risk in real time, and Intune compliance ensures only healthy, policy-adherent devices can connect. On the Microsoft Cybersecurity Architect exam, this question tests your ability to distinguish between modern Zero Trust controls and legacy perimeter solutions—a common trap is selecting VPN or Azure AD Application Proxy, which are outdated for this architecture. Remember the mnemonic "ICE": Internet Access, Conditional Access, and Endpoint compliance (Intune) are the three pillars that melt the old perimeter model.
SC-100 Design security solutions for infrastructure Practice Question
This SC-100 practice question tests your understanding of design security solutions for infrastructure. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 components are required to implement a Zero Trust network architecture using Microsoft Entra Internet Access (formerly Microsoft 365 Network Connectivity)?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Conditional Access policies
Options A, B, and D are correct because Entra Internet Access, Conditional Access, and Intune compliance are core Zero Trust components. Option C is wrong because VPN is traditional perimeter security. Option E is wrong because Azure AD Application Proxy (now Entra Application Proxy) is for legacy app publishing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Conditional Access policies
Why this is correct
Enforces access controls based on user, device, and location.

✗
Azure AD Application Proxy
Why it's wrong here
Application Proxy is for remote access to on-premises apps, not a Zero Trust component for internet access.
✗
Site-to-site VPN
Why it's wrong here
VPN is a legacy perimeter technology, not Zero Trust.
✓
Microsoft Intune device compliance policies
Why this is correct
Ensures devices meet security requirements before access.

Microsoft Entra Internet Access (Microsoft Global Secure Access)
Why this is correct
Provides secure internet access with traffic forwarding.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.

Variation 1. Which THREE components are required to implement a zero-trust network architecture in Azure using Microsoft security solutions?
hard
A.Microsoft Sentinel
B.Azure Bastion
✓ C.Microsoft Defender for Cloud Apps
✓ D.Microsoft Entra ID Conditional Access
✓ E.Azure Policy
Why C: Azure AD Conditional Access enforces access policies. Microsoft Defender for Cloud Apps provides cloud access security broker (CASB) functionality. Azure Policy ensures compliance. Azure Bastion is for secure connectivity. Microsoft Sentinel is for SIEM, not a core zero-trust component.
