SC-900 Exam Dumps - Microsoft Security Compliance and Identity Fundamentals

In Microsoft Entra ID Protection, risk-based Conditional Access policies use signals such as User risk and Sign-in risk to evaluate potential threats during authentication and identity usage. These are core to adaptive access and identity protection features taught in Microsoft’s SC-300 and SC-900 learning paths.

User risk:

Defined by Microsoft as: “The probability that a specific identity or account is compromised.”

User risk is assessed based on activities and behaviors that indicate the account may have been compromised—such as leaked credentials or atypical user activity over time.

Sign-in risk:

Defined as: “The probability that the authentication request is not performed by the legitimate identity owner.”

Sign-in risk is calculated at the time of authentication based on indicators such as unfamiliar locations, anonymous IP addresses, impossible travel, or malware-linked sign-ins.

These signals help automate access decisions, such as requiring MFA or blocking access, based on real-time risk assessments.

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.

Microsoft describes hybrid identity as integrating on-premises Active Directory with Microsoft Entra ID (Azure AD) so that “your on-premises identities are synchronized to Azure AD” for a single identity across cloud and on-prem apps. In this model, directory objects (users, groups, and selected attributes) flow from on-premises AD to Azure AD using Azure AD Connect or Cloud Sync; this is the canonical direction for provisioning in hybrid environments. Microsoft further explains that while certain writeback features (such as password writeback, device or group writeback scenarios) are supported, cloud-created users do not automatically sync down to on-premises AD; account provisioning remains authoritative on-prem unless you deploy specific, limited writeback features—there is no default “user account creation from Azure AD to AD DS.” For authentication, Microsoft states that hybrid identity supports cloud authentication (Password Hash Synchronization or Pass-through Authentication) where Azure AD performs the sign-in, or federation with another identity provider (e.g., AD FS or a third-party IdP) where that provider validates credentials and issues tokens to Azure AD. These statements align with Microsoft’s SCI guidance on hybrid identity: on-prem to cloud sync is standard; automatic reverse user sync is not; and authentication can be handled by Azure AD or a federated IdP depending on the chosen sign-in method.

Microsoft Defender for Identity (formerly Azure Advanced Threat Protection, also known as Azure ATP) is a cloud-based security solution that leverages your on-premises Active Directory signals to identify, detect, and investigate advanced threats, compromised identities, and malicious insider actions directed at your organization.

Box 1: Yes

The MailItemsAccessed event is a mailbox auditing action and is triggered when mail data is accessed by mail protocols and mail clients.

Box 2: No

Basic Audit retains audit records for 90 days.

Advanced Audit retains all Exchange, SharePoint, and Azure Active Directory audit records for one year. This is accomplished by a default audit log retention policy that retains any audit record that contains the value of Exchange, SharePoint, or AzureActiveDirectory for the Workload property (which indicates the service in which the activity occurred) for one year.

Box 3: yes

Advanced Audit in Microsoft 365 provides high-bandwidth access to the Office 365 Management Activity API.

In Microsoft’s official guidance, the Microsoft Cloud Adoption Framework for Azure (CAF) is described as the end-to-end approach that “provides best practices, documentation, and tools” to help organizations create and implement business and technology strategies for cloud adoption. The framework aggregates field experience from “Microsoft employees, partners, and customers” and offers prescriptive guidance across strategy, planning, readiness, governance, security, and management to ensure a secure and compliant Azure landing zone. Within SCI-aligned materials, CAF is highlighted as the authoritative body of guidance that helps organizations reduce risk by aligning cloud architecture, identity, security, and compliance controls with Zero Trust principles and regulatory needs. It enables teams to map security baselines, identity governance (e.g., using Microsoft Entra and Conditional Access), and compliance controls (e.g., data protection and regulatory mappings) into deployment blueprints and policy-driven guardrails.

By contrast, Azure Blueprints package artifacts (policies, RBAC, templates) for consistent deployments; Azure Policy enforces and audits configuration through policy definitions; and resource locks prevent accidental modification or deletion. While these are important technical controls, the statement in the question explicitly refers to a body of best practices and guidance that assists an Azure deployment end to end—this is precisely the role of the Microsoft Cloud Adoption Framework for Azure.

Endpoint data loss prevention (Endpoint DLP), a feature in Microsoft Purview, supports Windows 10 and 11 and now also supports macOS for core DLP capabilities. It allows organizations to monitor and restrict actions like copying sensitive files to USBs, printing, or uploading to unapproved cloud services.

SCI Extract: "Endpoint DLP extends Microsoft Purview Data Loss Prevention to Windows 10, Windows 11, and macOS devices, allowing for monitoring and control of sensitive data usage at the endpoint."

Other platforms like Linux, iOS, and Android are not currently supported for Endpoint DLP

ï‚· Microsoft Defender for Cloud can detect vulnerabilities and threats for Azure Storage. Yes

ï‚· Cloud Security Posture Management (CSPM) is available for all Azure subscriptions. Yes

ï‚· Microsoft Defender for Cloud can evaluate the security of workloads deployed to Azure or on-premises. Yes

Microsoft Defender for Cloud provides both workload protection and posture management. For Azure Storage, the Defender plan (Microsoft Defender for Storage) offers threat detection such as anomalous access, malware scanning, and sensitive-data threat alerts, while the CSPM guidance in Defender for Cloud flags misconfigurations that create vulnerabilities (for example, public blob access, weak TLS settings). CSPM capabilities—secure score, recommendations, and baseline assessments—are available to all Azure subscriptions (foundational CSPM), giving every tenant visibility into security posture without requiring a premium add-on for basic posture features. Beyond Azure, Defender for Cloud supports hybrid and multicloud: using Azure Arc and the Defender for Servers plan, it can onboard and assess on-premises servers and resources in other clouds, applying recommendations, security assessments, and threat protections across those environments. Collectively, these capabilities confirm that Defender for Cloud can detect storage-related threats and posture weaknesses, CSPM is broadly available to Azure subscriptions, and the service evaluates workloads running in Azure or on-premises.
