Microsoft SC-900 - Microsoft Security Compliance and Identity Fundamentals

In Microsoft’s SCI materials, the Solutions catalog is described as part of the Microsoft Purview experience: “The Microsoft Purview compliance portal is the home for solutions to manage your organization’s data security and compliance needs.” Within this portal, Microsoft states that “the Solutions catalog provides a single place to discover, learn about, and set up Microsoft Purview solutions.” The catalog organizes capabilities across compliance domains, for example “Information Protection, Data Lifecycle Management, Data Loss Prevention, Insider Risk Management, eDiscovery, Audit, and Compliance Manager,” and from the catalog “administrators can open setup guides and configuration wizards for each solution.” This positioning makes the Purview compliance portal the correct portal when you are asked where the solution catalog lives.

By comparison, the Microsoft 365 admin center focuses on tenant administration and licensing, the Microsoft 365 Defender portal consolidates threat protection and security operations, and the Microsoft 365 Apps admin center targets Office app management and servicing. None of these are identified as the home of the Purview Solutions catalog. Therefore, the portal that contains the solution catalog is the Microsoft Purview compliance portal.

Microsoft 365 Endpoint Data Loss Prevention (Endpoint DLP) extends DLP controls directly to supported desktops. Microsoft states: “Endpoint DLP extends the activity monitoring and protection capabilities of DLP to Windows 10 (and later) devices.” The platform coverage is explicitly broadened to Apple desktops: “Endpoint DLP for macOS enables the same set of DLP capabilities on macOS devices (supported versions) so you can monitor and protect sensitive items across Windows and Mac endpoints.” At the same time, Microsoft clarifies the mobile scope: “Endpoint DLP is supported on Windows and macOS devices.” This means Android is not a supported operating system for Endpoint DLP (mobile data protection on Android uses different controls such as app protection policies via Microsoft Intune and conditional access). Therefore, the correct pairing of operating systems for Endpoint DLP support is Windows 10 and newer, and macOS—not Android. This aligns with Microsoft’s Endpoint DLP platform support guidance and the intended desktop-focused endpoint protections for activities such as file copy, print, upload, and removable media interactions.

Microsoft’s SCI learning content describes the Microsoft 365 Defender portal as a unified security operations experience that surfaces security posture and active threats on a card-based dashboard. In the overview of the portal, Microsoft explains that the home page “presents key security information in dashboard cards,” and that among these cards are summaries that highlight risky entities such as “Users at risk” and “Devices at risk.” These cards provide quick, actionable visibility for analysts by aggregating detections and exposure data across Microsoft Defender services (for identities and endpoints). The guidance emphasizes that the portal “correlates signals across identities, endpoints, email, and applications” and that security teams can use the dashboard cards to pivot directly into incidents and investigations from “Users at risk” or “Devices at risk” to take containment or remediation actions.

By contrast, Compliance Score is part of Microsoft Purview Compliance Manager, not the Microsoft 365 Defender portal; Service Health and User Management are functions of the Microsoft 365 admin center. Therefore, the cards you’ll find on the Microsoft 365 Defender portal that match the choices provided are Users at risk and Devices at risk.

The recommended way to enable and use Azure AD Multi-Factor Authentication is with Conditional Access policies. Conditional Access lets you create and define policies that react to sign-in events and that request additional actions before a user is granted access to an application or service.

Azure AD Identity Protection (now part of Microsoft Entra ID) is the Microsoft service that “automates the detection and remediation of identity-based risks.” It continuously evaluates user risk and sign-in risk using signals such as leaked credentials, atypical travel, unfamiliar sign-in properties, and malware-linked IPs. Microsoft documentation clarifies that Identity Protection “uses adaptive machine learning and heuristics to detect risky behaviors and sign-ins” and enables administrators to configure risk-based policies (for example, require MFA or block access) to automatically respond. It also provides rich investigations through risk reports so security teams can triage and remediate compromised identities. This distinctly differs from other Entra capabilities: Privileged Identity Management (PIM) governs just-in-time privileged access and role activation, while MFA is an authentication method enforced by policies. Because the service that specifically detects risk and applies automated protection based on risk is Azure AD Identity Protection, it is the correct completion for the sentence about identity risk detection and remediation.QUESTION NO: 148 HOTSPOT

In Microsoft’s SCI guidance, Insider risk management is a Microsoft Purview capability surfaced and administered from the Microsoft Purview compliance portal. The official description states that Insider risk management “helps you minimize internal risks by enabling you to detect, investigate, and act on risky activities in your organization.” Microsoft further clarifies access and configuration by directing admins to “use the Microsoft Purview compliance portal to configure and manage insider risk policies, alerts, and investigations,” and that you can “go to the Microsoft Purview compliance portal and select Insider risk management” to start. These statements place the feature squarely in the compliance plane—not the Microsoft 365 admin center (tenant-wide service management), not the Microsoft 365 Defender portal (threat protection and incident response), and not Microsoft Defender for Cloud Apps (app discovery and cloud app protection). In the SCI learning path, Insider risk is consistently grouped with Microsoft Purview solutions (Information Protection, DLP, eDiscovery, and Audit), emphasizing compliance workflows, risk indicators, policy tuning, and case management. Therefore, the correct completion of the sentence “Insider risk management is configured from the” is the Microsoft Purview compliance portal, where administrators create policies, review alerts, investigate user activity timelines, and take appropriate remediation actions within a compliance-centric experience.

access and application control

In Microsoft Defender for Cloud, the capabilities grouped as access and application control are designed to harden Azure virtual machines by limiting both what can access a VM and what can run on it. Microsoft’s documentation explains that Adaptive application controls “help you control which applications can run on your VMs by allowing only known-safe applications,” which directly helps block malware and other unwanted applications. In the same family, Just-in-time (JIT) VM access “reduces exposure to attacks by locking down inbound traffic to your VMs and opening only the required ports, for approved users, for a limited time,” thereby reducing the network attack surface. These capabilities are surfaced in Defender for Cloud recommendations and policies to enforce least privilege at the network edge and on the endpoint execution layer.

By contrast, Cloud Security Posture Management (CSPM) provides continuous assessment and secure-score-driven recommendations but isn’t the control that actively blocks applications or time-bounds inbound access. Container security targets container images and runtimes, and vulnerability assessment identifies software vulnerabilities but doesn’t enforce allow-listing or time-bound access. Therefore, the correct completion is access and application control, which encompasses Adaptive application controls and JIT VM access to protect VMs from unwanted apps and minimize exposed network surface.

In Microsoft Purview eDiscovery, to search, preserve, analyze, and export content, you must first create a case. A case acts as a container for all eDiscovery activities, including placing users and content locations on litigation hold, running content searches, and exporting results for legal or compliance review.

SCI Extract: " Cases are used in Microsoft Purview eDiscovery (Standard and Premium) to manage, organize, and execute the various tasks associated with identifying and delivering content during an investigation or litigation. "

In Microsoft identity architecture, federation establishes trust between different identity providers to enable single sign-on (SSO) across organizational and platform boundaries. Microsoft Learn explains that federation uses standards such as SAML, WS-Federation, and OpenID Connect/OAuth 2.0 so a user can authenticate with their home identity provider and obtain tokens that are accepted by a relying party (the application or service). This trust relationship lets organizations share identities securely without copying passwords or synchronizing credentials, providing a seamless sign-in experience across multiple systems and clouds.

By contrast, Active Directory Domain Services (AD DS) and a domain controller provide on-premises directory and authentication services primarily within a single Windows domain/forest using Kerberos/NTLM, not cross-provider SSO on their own. Microsoft Entra Privileged Identity Management (PIM) manages just-in-time, approval-based elevation for roles and does not deliver SSO capabilities. Therefore, the technology explicitly intended to provide SSO across multiple identity providers is federation.

In Microsoft’s Security, Compliance, and Identity guidance, Data Loss Prevention (DLP) is configured from the compliance portal (formerly called the Microsoft 365 Compliance Center, now Microsoft Purview compliance portal). Microsoft’s documentation states that DLP is administered from the compliance experience: “Use data loss prevention (DLP) policies in the Microsoft Purview compliance portal to help identify, monitor, and automatically protect sensitive items” across Microsoft 365 workloads. It further specifies where you create policies: “To create a DLP policy, go to the Microsoft Purview compliance portal > Data loss prevention > Policies and choose Create policy.” The portal provides policy templates, locations, and rules that “help prevent the inadvertent sharing of sensitive information” and enable “policy tips and automatic remediation actions” (such as restricting access, auditing, or blocking).

By contrast, the Microsoft 365 admin center is for tenant administration and licensing, not DLP policy authoring. The Microsoft Endpoint Manager admin center (Intune) manages device and app protection policies, not Microsoft 365 DLP policies. The Microsoft 365 Defender portal surfaces security alerts and investigations but does not host the creation workflow for DLP policies. Therefore, when the requirement is to create a DLP policy, Microsoft directs administrators to the Microsoft 365 Compliance center (Microsoft Purview compliance portal) where the DLP solutions and policy creation wizard reside.
