SC-900 Practice Questions

Box 1: Yes

Azure Defender provides security alerts and advanced threat protection for virtual machines, SQL databases, containers, web applications, your network, your storage, and more

Box 2: Yes

Cloud security posture management (CSPM) is available for free to all Azure users.

Box 3: Yes

Azure Security Center is a unified infrastructure security management system that strengthens the security posture of your data centers, and provides advanced threat protection across your hybrid workloads in the cloud - whether they ' re in Azure or not - as well as on premises.

Yes

NO

NO

YES - As an administrator, you can lock a subscription, resource group, or resource to prevent other users in your organization from accidentally deleting or modifying critical resources. The lock overrides any permissions the user might have.

NO - The most restrictive lock in the inheritance takes precedence.

NO - If you delete a resource group with a locked resource, the portal UI will give you an error and no resources are deleted.

In Microsoft’s Security, Compliance, and Identity materials, Customer Lockbox is described as the feature that controls any Microsoft engineer access to your tenant content during support operations. Microsoft states that Customer Lockbox “ensures that Microsoft cannot access your content to perform a service operation without your explicit approval.” It is specifically applicable to Microsoft 365 workloads that store customer data, including “Exchange Online, SharePoint Online, and OneDrive for Business.” When a support case requires elevated access, “a lockbox request is created and routed to the customer for approval or rejection,” and access is only granted if the organization’s authorized admin approves the request within the defined window. The request contains who is requesting access, the reason, the scope, and the duration, and all actions are audited for compliance reporting. This capability aligns with Microsoft’s zero standing access principles by making engineer access time-bound, least-privileged, and customer-approved. By contrast, Information barriers segregate communications between groups, Privileged Access Management (PAM) governs privileged tasks inside Microsoft 365, and Sensitivity labels classify and protect data. Therefore, the feature that “can be used to provide Microsoft Support Engineers with access to an organization’s data stored in Microsoft Exchange Online, SharePoint Online, and OneDrive for Business” is Customer Lockbox.

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 Purview Insider Risk Management is designed to identify, investigate, and act on risky activities by internal users—for example data exfiltration, data theft, policy violations, and user sentiments/signals that may indicate insider risk. SCI documentation explains that Insider Risk policies analyze signals such as file downloads, copying to USB, sharing to personal cloud, printing, or anomalous activity following events like performance warnings or resignation notices. Because it focuses on insider behaviors, it is not used to detect external threat vectors like phishing scams; those are addressed by Microsoft Defender for Office 365 and related anti-phishing protections—hence statement 1 is No. The solution is accessed in the Microsoft Purview (formerly Microsoft 365) compliance center under Insider risk management, where admins configure policies, alerts, and workflows—so statement 2 is Yes. Finally, its core purpose includes detecting and investigating potential data leaks by disgruntled or departing employees, using built-in policy templates (e.g., Data theft by departing employee, Data leaks), making statement 3 Yes.

Multi-factor authentication is a process where a user is prompted during the sign-in process for an additional form of identification, such as to enter a code on their cellphone or to provide a fingerprint scan.
