The correct answer is to onboard multiple workspaces to Azure Lighthouse and use a central workspace for investigation. This configuration is required because Azure Lighthouse provides cross-tenant management capabilities, allowing a Security Operations Center (SOC) to delegate access to multiple Microsoft Sentinel workspaces from a single control plane. By centralizing investigation in one workspace, analysts can view and manage incidents across all tenants without separate sign-ins or data duplication, which is essential for efficient multi-tenant Sentinel operations. On the SC-200 exam, this scenario tests your understanding of how Azure Lighthouse enables unified security monitoring without replicating log data—a common trap is assuming you need to ingest all logs into one workspace, which violates data residency and cost principles. Remember the key distinction: Azure Lighthouse delegates access, not data; think of it as a “single pane of glass” for permissions, not storage. A helpful memory tip is “Lighthouse lights the way to cross-tenant visibility without moving the data.”
SC-200 Manage a security operations environment Practice Question
This SC-200 practice question tests your understanding of manage a security operations environment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Your organization is implementing Microsoft Sentinel in a multi-tenant environment using Azure Lighthouse. The SOC team needs to investigate incidents across all tenants from a single interface. Which configuration is required?
Use Azure AD B2B to grant users from other tenants access to the workspace.
Why wrong: B2B allows access but does not enable unified incident management across tenants.
B
Create a single workspace and have all tenants send logs to it.
Why wrong: Microsoft Sentinel workspaces are bound to a single tenant; you cannot have multiple tenants send logs to one workspace without special configuration.
C
Assign custom roles in each tenant's Sentinel workspace.
Why wrong: Custom roles per tenant still require separate logins and interfaces.
D
Onboard multiple workspaces to Azure Lighthouse and use a central workspace for investigation.
Azure Lighthouse delegates resources across tenants, enabling centralized management in Sentinel.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Onboard multiple workspaces to Azure Lighthouse and use a central workspace for investigation.
Option D is correct because Azure Lighthouse enables cross-tenant management by allowing the SOC team to delegate access to multiple Sentinel workspaces from a single control plane. This configuration lets investigators view and manage incidents across all tenants without needing separate sign-ins or duplicating data, which is essential for a multi-tenant SOC environment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure AD B2B (external user access) with Azure Lighthouse (delegated resource management), assuming that granting external identities access to a single workspace is sufficient for multi-tenant incident investigation, when in fact Lighthouse is required to project multiple workspaces into a single management plane.
Detailed technical explanation
How to think about this question
Azure Lighthouse uses Azure Resource Manager delegated resource management to project resources from multiple tenants into a managing tenant. When combined with Microsoft Sentinel, the SOC team can use a central workspace (often in the managing tenant) to query and investigate incidents across all delegated Sentinel workspaces via cross-workspace queries, leveraging the `workspace()` expression in KQL. This setup respects each tenant's data boundaries while enabling unified monitoring, which is critical for managed security service providers (MSSPs) handling compliance-sensitive data.

Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
