SC-900 Exam Dumps - Microsoft Certified: Security Compliance and Identity Fundamentals Questions and Answers

 Security defaults require an Azure Active Directory (Azure AD) Premium license. No

 Security defaults can be enabled for a single Azure Active Directory (Azure AD) user. No

 When Security defaults are enabled, all administrators must use multi-factor authentication (MFA). Yes

Microsoft explains that Security defaults are baseline identity protections that are “available to all tenants at no additional cost” and are intended to “help protect your organization from common identity-related attacks.” They are a tenant-wide setting: Microsoft states that security defaults are “either on or off for the entire tenant” and “can’t be customized or targeted to specific users or groups.” If you require per-user or granular targeting, Microsoft directs customers to use Conditional Access policies instead.

A core behavior of security defaults is enforcing MFA: “All users are required to register for Azure AD Multi-Factor Authentication,” and “administrators are required to perform MFA.” In addition, security defaults “block legacy authentication” and apply other baseline requirements, but they do not enable premium features such as Azure AD Identity Protection or PIM. Summarizing the implications for the statements: no premium license is required; you cannot enable security defaults for just one user because the control is global; and when enabled, administrators must use MFA, with Microsoft recommending exclusion only for a break-glass account if necessary.

Microsoft Defender for Office 365 includes Safe Attachments, a protection that “checks attachments in a secure, virtual environment to detect malicious behavior.” In Microsoft’s guidance, Safe Attachments is described as part of the anti-malware pipeline that “routes messages with attachments to a detonation chamber; if no suspicious activity is detected, the message is released to the recipient, and if malicious behavior is found, the attachment is blocked or removed.” Administrators can choose Block, Replace, Dynamic Delivery, or Monitor actions. The Dynamic Delivery option specifically supports the use case in the question: the email body is delivered while the attachment is scanned, and “the attachment is automatically reattached and forwarded to the recipient only when it is determined to be safe.” This capability is unique to Defender for Office 365’s Safe Attachments, not to be confused with endpoint antivirus or identity tools. Defender Antivirus protects Windows devices, Defender for Identity secures on-premises identities, and Defender for Endpoint focuses on endpoint detection and response. Therefore, the Microsoft service you use to scan email attachments and forward them only when clean is Microsoft Defender for Office 365 (Safe Attachments).

Microsoft Entra ID Protection evaluates risk during authentication, not only after the user is authenticated. The service provides “real-time” assessment as part of the sign-in flow and also processes “offline” detections, enabling Conditional Access to act before a session is granted. In Microsoft’s terminology, “sign-in risk represents the probability that a given authentication request isn’t authorized by the identity owner,” while “user risk represents the probability that a given identity or account is compromised.” These risks are surfaced as risk detections and can be used to trigger MFA, block access, or require secure password reset. Each detection and calculated risk is classified by Microsoft Entra ID Protection with “Low, Medium, or High” levels so administrators can triage and automate policy responses appropriately. Because detections are calculated in real time as part of the sign-in evaluation (and also through subsequent analysis), it is incorrect to say they are generated once the user is authenticated. The accurate view is that Identity Protection continuously analyzes telemetry and produces detections and risk levels that may be acted upon before, during, and after sign-in, with user risk expressing the likelihood that the identity itself is compromised and sign-in risk expressing the likelihood that a particular authentication attempt is not legitimate.

Azure Blueprints allow cloud architects and central IT to define a repeatable set of Azure resources and governance artifacts—including Azure Policy assignments, role assignments (RBAC), resource groups, and ARM/Bicep templates—and then deploy them consistently across subscriptions. Microsoft’s guidance describes Blueprints as a way to “orchestrate the deployment of various resource templates and other artifacts” to establish standards, patterns, and compliance for environments at scale. This is distinct from Azure Policy, which evaluates and enforces configuration but does not package multi-artifact environments; Microsoft Sentinel and Defender are security analytics/protection services rather than provisioning frameworks. Thus, for consistent provisioning across multiple subscriptions, the prescribed solution is Azure Blueprints.

Microsoft Entra ID (formerly Azure Active Directory) is a cloud-based directory and identity platform. In Microsoft’s SCI materials, Entra ID is described as “Microsoft’s cloud-based identity and access management service that helps your employees sign in and access resources,” underscoring that it’s not deployed on-premises; instead, organizations can synchronize or federate with on-premises Active Directory using tools like Entra Connect. The same documentation explains that Entra ID is included with Microsoft 365 subscriptions, providing tenant identity services for apps such as Exchange Online, SharePoint Online, and Teams. Core capabilities listed include authentication, single sign-on (SSO), Conditional Access, device registration, and application access management, all of which classify Entra ID as an identity and access management (IAM) service. Thus: (1) on-premises deployment — No (it’s cloud-native), (2) provided with Microsoft 365 — Yes (a directory is created for each tenant), and (3) IAM service — Yes (it delivers identity, access, and governance controls used across Microsoft cloud services).

Microsoft Entra ID Identity Protection is a risk-based conditional access capability that “automates the detection and remediation of identity-based risks” and enables admins to investigate risky users and sign-ins. SCI guidance explains that Identity Protection evaluates signals such as user risk and sign-in risk, raises risk detections, and can automatically remediate by enforcing actions like password reset or blocking access via risk-based policies. The portal provides rich investigation experiences for risky users, risky sign-ins, and risk detections, allowing security teams to review evidence and confirm/dismiss risks. In addition, identity risk data can be exported through Azure Monitor/diagnostic settings and integrated with SIEM/SOAR tools, enabling “export of risk detections and security alerts to third-party solutions” for correlation and response. Tasks such as configuring external access for partner organizations are handled by B2B collaboration features, and creating/assigning sensitivity labels belongs to Microsoft Purview Information Protection—not Identity Protection. Therefore, the tasks Identity Protection supports are: export risk detection (B), automate detection and remediation of identity-based risks (C), and investigate risks related to user authentication (D).

Microsoft defines defense in depth as a security strategy that uses multiple, reinforcing layers of protection to reduce the chance that a single failure leads to compromise. In Microsoft’s security guidance, defense in depth is described as employing “a series of mechanisms across multiple layers” to protect identities, endpoints, applications, data, and the network. The model spans layers such as identity, perimeter, network, compute, application, and data, with controls at each layer designed to detect, prevent, and contain attacks. Typical Azure/Microsoft 365 implementations include identity protections (MFA, Conditional Access), network controls (Azure Firewall, NSGs), perimeter filtering (WAF, DDoS Protection), endpoint safeguards (Defender for Endpoint), application security (code and runtime controls), and data protection (encryption, DLP, Purview Information Protection). By “placing multiple layers of defense throughout a network infrastructure,” an organization limits blast radius and increases resilience if one layer is bypassed. This contrasts with threat modeling (a design-time analysis technique), identity as the security perimeter (a principle of Zero Trust), and the shared responsibility model (a cloud governance concept). The scenario in the question precisely matches Microsoft’s defense in depth methodology.

Explanation

Azure Active Directory (Azure AD) access reviews enable organizations to efficiently manage group memberships, access to enterprise applications, and role assignments.

In Microsoft Entra Conditional Access, policy evaluation occurs after the user successfully completes first-factor authentication (for example, username + password or Windows Hello for Business key). Microsoft Learn explains that Conditional Access “is the tool used by Azure AD to bring signals together, make decisions, and enforce organizational policies” and that it’s applied “after the first-factor authentication is completed.” Once primary authentication succeeds, Conditional Access evaluates signals like user, device state, location, risk (from Identity Protection), and application, and then enforces controls such as requiring MFA, blocking access, or applying session controls.

This design ensures Conditional Access does not replace primary authentication and is not enforced before or during the initial credential verification. Instead, it adds a second policy decision point that can demand stronger proof (e.g., MFA), restrict access paths, or limit sessions. Therefore, “after” is correct, while “before,” “during,” or “instead of” first-factor authentication are incorrect because Conditional Access relies on the initial sign-in to collect the necessary signals and then applies the configured access decisions and protections.
