Free SC-300 Practice Exam Questions 2026 (With Explanations) — Identity & Access Administrator (IAM)

Q: [OVERVIEW]Following a corporate acquisition, GlobalTech Group operates two separate Microsoft Entra ID tenants: `Tenant A` (parent workforce, 12,000 identities) and `Tenant B` (acquired subsidiary hosting unified M365 and Teams collaboration apps).[/OVERVIEW] [ENVIRONMENT]• Identity Landscape: Both tenants belong to the same Multi-Tenant Organization (MTO) governance boundary. • Manual CSV scripting and legacy AD FS trusts are strictly forbidden by modern Zero Trust engineering standards.[/ENVIR

D. Cross-tenant synchronization (built on the Entra provisioning service) — Cross-tenant synchronization automates creating, updating, and deleting B2B collaboration users across tenants in the same organization using the Microsoft Entra provisioning service.

Q: [OVERVIEW]Litware Enterprise hires 250 remote engineers monthly using Workday synced to Microsoft Entra ID, with zero IT Helpdesk manual ticket intervention allowed prior to Day 1.[/OVERVIEW] [ENVIRONMENT]• HR Trigger Attribute: `employeeHireDate` is populated automatically from Workday upon contract signature. • Day-minus-7 Automation: Seven days before the employee's start date, Entra ID must pre-provision permissions, generate a time-bound Temporary Access Pass (TAP), and send an onboarding e

A. Lifecycle Workflows (Joiner workflow template based on employeeHireDate) — Lifecycle Workflows in Entra ID Governance automate lifecycle tasks (Joiner-Mover-Leaver) triggered by HR employee attributes (such as employeeHireDate) with built-in tasks like TAP generation and group assignments.

Q: How does Privileged Access Management (PAM) in Microsoft 365 Purview protect sensitive administrative tasks in Exchange Online and SharePoint Online?

D. By requiring explicit, just-in-time approval before an administrator can execute high-impact PowerShell cmdlets (such as Journaling rules or Mailbox search exports) — Privileged Access Management (PAM) in Microsoft Purview provides granular task-based access control. Administrators must request approval before executing predefined sensitive PowerShell commands in Exchange Online.

Q: What is the most efficient way to periodically review and clean up all external guest users who have access to Microsoft 365 Groups and Teams across the entire tenant?

D. Create an Access Review in Identity Governance targeting "Teams + Groups", selecting "All Microsoft 365 Groups with guest users", scoping to "Guest users only", with recurring quarterly reviews assigned to Group Owners — Entra Access Reviews allows creating a tenant-wide recurring review targeting all Microsoft 365 groups with guest users. Group owners review whether guest access is still needed, and inactive guests are automatically removed.

Q: How does Microsoft Entra Privileged Identity Management (PIM) for Azure Resources protect Azure subscriptions from configuration tampering?

D. By allowing cloud engineers to be assigned as "Eligible" for high-privilege Azure RBAC roles (like Subscription Owner or Contributor), requiring just-in-time activation with MFA and justification when maintenance is needed — PIM for Azure Resources manages just-in-time access for Azure RBAC roles at management group, subscription, resource group, and resource levels, eliminating standing Owner and Contributor privileges on subscriptions.

Q: An enterprise utilizes an external third-party Security Information and Event Management (SIEM) platform (such as Splunk or QRadar). How can Microsoft Entra audit logs and sign-in logs be streamed in near real-time to the external SIEM?

D. Configure Microsoft Entra Diagnostic Settings to stream log categories to an Azure Event Hub, which feeds the external SIEM collector — Streaming Microsoft Entra diagnostic logs to Azure Event Hubs provides high-throughput, low-latency log ingestion for third-party SIEM and analytics solutions like Splunk, IBM QRadar, or Sumo Logic.

Q: [SCENARIO]You configure a quarterly Microsoft Entra Access Review covering 800 B2B guest accounts across Microsoft 365 Groups so business owners certify continued external partner access without manual spreadsheet auditing.[/SCENARIO] [SOLUTION]Management mandates two safeguards inside the Access Review wizard: (1) reviewers must visually see automated system insights highlighting guests inactive for > 30 days, and (2) stale guests must lose access automatically even if an unresponsive group own

D. Enable 'Decision helpers' (system recommendations based on 30-day inactivity) and set 'If reviewers don't respond' to 'Take recommendations' (or 'Remove access') with 'Auto apply results to resource' checked — Decision helpers show reviewers whether a user has signed in during the past 30 days. Enabling auto-apply and configuring the default action on non-response ensures access is revoked even if reviewers fail to act.

Q: [SCENARIO]An organization is retiring legacy inbound VPN concentrators for 5,000 hybrid workers and migrating toward Microsoft's Security Service Edge (SSE) Zero Trust architecture.[/SCENARIO] [SOLUTION]Employees require identity-aware, per-app Zero Trust Network Access (ZTNA) to legacy on-premises TCP/RDP/SMB internal applications across any port—without publishing those servers to the public internet or opening inbound corporate firewall ports.[/SOLUTION] [QUESTION]Which specific component of

A. Microsoft Entra Private Access — Microsoft Entra Private Access (part of Microsoft's Security Service Edge solution) provides identity-aware Zero Trust network access (ZTNA) to private internal resources on any port/protocol using lightweight private connectors.

Q: You are configuring Microsoft Entra Conditional Access authentication strengths to defend against adversary-in-the-middle (AiTM) phishing attacks. You need to require phishing-resistant MFA for all administrators accessing Azure Portal. Which TWO authentication methods fulfill the built-in "Phishing-resistant MFA" authentication strength? (Choose two.)

A. Windows Hello for Business backed by hardware TPM attestation. & D. FIDO2 security keys (such as YubiKeys). — CORRECT: Options B and E. - Phishing-resistant MFA in Microsoft Entra ID includes FIDO2 security keys, Windows Hello for Business, and Certificate-Based Authentication (CBA). INCORRECT DISTRACTORS: - Options A, C, and D are susceptible to interception and AiTM proxy relay attacks.

Q: Which TWO foundational components are required when establishing a decentralized identity issuance and verification infrastructure with Microsoft Entra Verified ID? (Choose two.)

A. A verified public domain name (DNS) with a hosted did-configuration.json file for domain linking validation. & D. An Azure Key Vault instance to generate and store the decentralized identifier (DID) signing and encryption keys. — CORRECT: Options B and E. - Microsoft Entra Verified ID relies on Azure Key Vault to safeguard DID cryptographic keys. - Domain verification requires publishing the well-known did-configuration.json file over HTTPS on the verified DNS domain. INCORRECT DISTRACTORS: - Options A, C, and D are obsolete or insecure.
