Pass the Microsoft Microsoft Certified: Security Compliance and Identity Fundamentals SC-900 Questions and answers with CertsForce

In Microsoft’s Security, Compliance, and Identity (SCI) learning content, Multi-Factor Authentication (MFA) is defined as requiring more than one verification method during sign-in. Microsoft states: “Multi-factor authentication (MFA) requires two or more verification methods” and Azure AD (Microsoft Entra ID) MFA “works by requiring two or more of the following: something you know (password), something you have (trusted device or token), something you are (biometrics).” The SCI fundamentals also explain that MFA strengthens authentication beyond a single password by combining distinct factor types, noting that “strong authentication uses at least two different factors to verify identity.”

When you enable Azure AD MFA, a user must successfully present two factors from those categories to complete the authentication—commonly a password (something you know) plus a second factor such as Microsoft Authenticator approval, a FIDO2 security key, SMS/voice code, or Windows Hello (something you have/are). This is the core of Azure AD’s risk-based and conditional access controls, which can require MFA based on conditions or risk signals. Therefore, the number of factors required after enabling Azure AD MFA is two, aligning with Microsoft’s definition and implementation of multi-factor authentication in Entra ID.

In Microsoft’s Security, Compliance, and Identity guidance, encryption is described as the control that “converts data into a form that cannot be understood by anyone who does not possess the appropriate decryption key.” In the Microsoft Purview Information Protection (sensitivity labels with encryption) documentation, Microsoft explains that when encryption is applied to a file, “only authorized users and services that present the correct keys and usage rights can open and use the content,” and that access is enforced even if the file is moved outside the organization. Azure Rights Management (part of Microsoft Purview) further states that encryption “protects data at rest and in transit by using keys so that only permitted identities can decrypt and use the information.”

This aligns precisely with the sentence: encrypting a file makes the data readable and usable to viewers that have the appropriate key (and unreadable to those who do not). By contrast, archiving organizes or preserves data for long-term storage; compressing reduces file size without controlling access; and deduplicating removes redundant copies to save space. None of these provide the key-based, identity-bound access control described in Microsoft SCI materials. Therefore, the correct completion is Encrypting.

In Microsoft’s Security, Compliance, and Identity guidance, Microsoft Defender for Identity (formerly Azure ATP) is explicitly described as “a cloud-based security solution that leverages your on-premises Active Directory signals to identify, detect, and investigate advanced threats.” The service deploys lightweight sensors on domain controllers to collect and analyze Active Directory (AD) authentication and activity data. Using behavioral analytics and built-in detections, it helps security teams surface indicators of compromised identities, lateral movement, pass-the-ticket/NTLM relay, and other identity-driven attack techniques. Documentation further explains that Defender for Identity “profiles and learns entity behavior,” correlates events, and raises security alerts with investigation timelines and evidence to accelerate incident response in hybrid environments.

This precisely matches the sentence in the prompt: the only Microsoft security product whose core purpose is to use on-premises AD signals to identify, detect, and investigate advanced threats is Defender for Identity. By contrast, Microsoft Defender for Endpoint focuses on endpoint prevention and EDR; Microsoft Defender for Office 365 protects email and collaboration workloads from phishing and malware; and Microsoft Cloud App Security (now Microsoft Defender for Cloud Apps) operates as a CASB for app discovery, control, and session monitoring. Therefore, aligning with SCI study guides and product descriptions, the correct completion is Microsoft Defender for Identity.

Microsoft Defender for Endpoint includes Automated investigation and remediation (AIR) and Attack surface reduction (ASR) as core capabilities. Microsoft’s guidance states that AIR “uses inspection algorithms and playbooks to examine alerts, determine if they are malicious, and then take remediation actions such as stopping processes, quarantining files, and rolling back changes.” It is designed to “reduce the volume of alerts that require analyst attention and to remediate threats at machine speed across your estate,” helping security teams contain and fix issues without manual intervention.

Defender for Endpoint also provides attack surface reduction features to proactively limit exposure. The Microsoft learn materials describe that ASR “helps organizations minimize areas that attackers can exploit,” and includes “attack surface reduction rules, network protection, web protection, application control (Windows Defender Application Control), and controlled folder access.” These controls “block or constrain risky behaviors and common attacker techniques,” thereby preventing many initial compromise and lateral-movement attempts before they generate incidents.

By contrast, transport encryption is a general platform/security baseline capability rather than a specific Defender for Endpoint feature, and shadow IT detection is addressed through Microsoft Defender for Cloud Apps (App discovery), which can use Defender for Endpoint network signals but is not itself a native MDE capability. Therefore, the two correct capabilities of Microsoft Defender for Endpoint are Automated investigation and remediation and Attack surface reduction.

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

Select the answer that correctly completes the sentence.

Answer:

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.

In Microsoft cloud identity, access to Azure resources follows the classical order of authenticate, then authorize. Microsoft Learn defines the two steps clearly: “Authentication is the process of establishing the identity of a person or service,” while “Authorization is the process of determining what a person or service can do.” In an Azure sign-in, Microsoft Entra ID (formerly Azure AD) first validates the user’s credentials (password, MFA, Conditional Access, device compliance, risk evaluation). Upon success, a security token is issued that proves the user’s identity. Only after this identity is established does Azure proceed to authorization, where the Azure Resource Manager evaluates role-based access control (RBAC) assignments to decide what actions are allowed. SCI guidance emphasizes this sequence for Zero Trust: “Verify explicitly” (authenticate with strong signals) and then “use least privilege access” (authorize by RBAC or Privileged Identity Management). Therefore, when users sign in to the Azure portal, the first step is authentication—verifying who they are. The subsequent step is authorization, which determines what resources and operations they can access based on roles, scope, and policy. This ordering underpins secure identity and access management across Microsoft 365 and Azure.

Microsoft Entra Access Reviews are designed to help organizations regularly validate and right-size access. Microsoft’s documentation explains that access reviews can target group memberships, enterprise app assignments, Azure AD roles, and Azure resource roles (via Privileged Identity Management), allowing reviewers to assess whether users, service principals, or groups should retain access to Azure resources—confirming the first statement. Access Reviews support automation: you can configure a review to “Auto-apply results”, so when the review ends, users who were denied or not reviewed are automatically removed from the group, application assignment, or role—validating the second statement. Finally, Access Reviews are a Premium P2 capability (now Microsoft Entra ID P2) alongside PIM and advanced identity governance. They are not included in all service plans; tenants require the appropriate P2 licenses for reviewers and users in scope—therefore the third statement is No.

The Service Trust Portal is Microsoft’s public-facing portal that centralizes how Microsoft manages privacy, compliance, and security for its cloud services. It provides independent audit reports, compliance guides, data protection resources, and details on Microsoft’s internal controls and practices. It’s the authoritative place to learn how Microsoft meets global, regional, and industry standards.

In the Microsoft Purview compliance portal, administrators can tailor the user experience to match the roles and responsibilities of users in the organization. One key feature provided to enable this customization is the “Customize navigation” option.

According to Microsoft’s Security, Compliance, and Identity (SCI) learning paths and SC-series certification materials (especially SC-400 and SC-900), the Customize navigation option in the Microsoft Purview compliance portal is used to add, remove, or rearrange features in the navigation pane. This is especially useful for compliance or security administrators who want to streamline the portal for ease of use or hide sections that are not relevant to their work.

The SCI documentation states:

“The Microsoft Purview compliance portal provides a Customize navigation option that allows admins to personalize the left-hand navigation pane. This feature supports removing unused features or rearranging the order in which services appear, improving navigation efficiency and reducing clutter.”

This setting does not change permissions or access to features but purely controls the visibility and layout for users. The other listed options like Compliance Manager, Policies, and Settings are functional sections of the portal, but only "Customize navigation" is explicitly designed to manage the visual layout and visibility of the features shown in the portal's navigation pane.

Microsoft’s Zero Trust guidance defines three core principles: “Verify explicitly, use least-privileged access, and assume breach.” In Microsoft’s SCI learning content and Zero Trust overview, the model is described as one that “treats every access attempt as though it originates from an open, untrusted network” and therefore requires explicit verification using all available signals (identity, device health, location, data sensitivity, and anomalies). This directly confirms the first statement as true: Verify explicitly is a guiding principle.

The same guidance states organizations must “assume breach”—designing controls so that if an attacker is already inside, blast radius is minimized through segmentation, Just-In-Time/Just-Enough-Access, continuous monitoring, and rapid detection and response. Microsoft’s Zero Trust materials repeatedly explain to “assume attackers are present” and to “contain and remediate” through defense-in-depth controls, which validates the second statement as true.

Finally, Zero Trust rejects perimeter-based implicit trust. Microsoft clarifies that the model does not rely on a trusted internal network protected by a firewall; instead it “never trusts, always verifies,” continuously enforcing policy regardless of network location (on-premises or internet). Therefore, the statement that Zero Trust assumes a firewall secures the internal network from external threats is false because Zero Trust presumes no inherent safety from being “inside” the network and requires continuous verification and least-privileged access everywhere.
