SC-100 Microsoft Entra ID Protection Practice Question

This SC-100 practice question tests your understanding of design security operations, identity, and compliance capabilities. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: microsoft Entra ID Protection. 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.

You are a security architect for a global financial services company that uses Microsoft 365 E5 and Azure. The company has 50,000 users across 10 regions. The security team needs to detect and respond to identity-based threats in real-time, automate remediation for compromised accounts, and meet regulatory requirements for audit logging. The following requirements must be met: (1) Detect risky sign-ins and user anomalies, (2) Automatically block sign-ins when risk level is high, (3) Provide a centralized dashboard for security analysts to investigate incidents, (4) Retain logs for at least one year for compliance, (5) Minimize false positives by using machine learning. You have the following services available: Microsoft Entra ID P2, Microsoft Sentinel, Microsoft Defender for Identity, Microsoft Purview, and Microsoft Intune. Which combination of services should you use to meet all requirements?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "least"

    Why it matters: You want the option with minimum overhead, fewest steps, or lowest impact — not the most feature-rich or comprehensive answer.

  • Clue: "minimum / minimize"

    Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Microsoft Entra ID Protection (P2) and Microsoft Sentinel

Option B is correct because Microsoft Entra ID Protection (included in P2 license) detects risky sign-ins and user anomalies, and can automatically block high-risk sign-ins via conditional access policies. Microsoft Sentinel ingests logs from Entra ID and other sources, provides a centralized SIEM dashboard for investigation, supports long-term log retention (up to two years) for compliance, and uses machine learning to reduce false positives. Option A is wrong because Microsoft Intune is for mobile device and app management, not identity threat detection, and Defender for Cloud focuses on cloud workload protection. Option C is wrong because Defender for Identity is designed for on-premises Active Directory, not cloud-only identity, and Purview is for data governance. Option D is wrong because Purview is for data governance, not identity threat detection; Sentinel alone cannot provide the risk-based conditional access controls that Entra ID Protection offers.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Microsoft Intune and Microsoft Defender for Cloud

    Why it's wrong here

    Intune is for device management; Defender for Cloud is for cloud workload protection, not identity.

  • Microsoft Entra ID Protection (P2) and Microsoft Sentinel

    Why this is correct

    Entra ID Protection detects risks and blocks high-risk sign-ins; Sentinel provides centralized SIEM with long-term retention.

    Clue confirmation

    The clue words "least", "minimum / minimize" in the question point toward this answer.

    Related concept

    Microsoft Entra ID Protection

  • Microsoft Defender for Identity and Microsoft Purview

    Why it's wrong here

    Defender for Identity is for on-premises AD; Purview is for data governance.

  • Microsoft Purview and Microsoft Sentinel

    Why it's wrong here

    Purview does not detect identity threats; Sentinel alone lacks identity threat detection.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Candidates often confuse Microsoft Defender for Identity (on-premises AD) with Entra ID Protection (cloud identity). The question specifies a cloud-only environment with Microsoft 365 and Azure, so Defender for Identity is not suitable.

Detailed technical explanation

How to think about this question

Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

  • False Positive Reduction

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

Microsoft Entra ID Protection

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.
