In Microsoft 365, the unified audit log retention depends on the audit tier included with the subscription.
Current SCI/Compliance documentation states that Audit (Standard)-which is available with Microsoft 365 E3-retains audit records for 180 days. The docs describe that organizations with E3 receive "up to 180 days of audit log retention" for user and admin activities captured in the unified audit pipeline. Longer retention (for example 365 days and beyond with customizable policies) is part of Audit (Premium) features generally associated with E5/E5 Compliance. Because the scenario specifies a Microsoft 365 E3 subscription using the unified audit log and Basic/Standard Audit, the retention period for audit records is 180 days.

Explanation:

Microsoft's identity guidance for Azure resources states there are two kinds of managed identities: system- assigned and user-assigned. The documentation describes that a system-assigned identity is scoped to a single resource and follows its lifecycle: "A system-assigned managed identity is created in Microsoft Entra ID and is tied to the lifecycle of that Azure service instance. When the resource is deleted, Azure automatically deletes the identity." By contrast, a user-assigned identity is reusable across resources: "A user-assigned managed identity is a standalone Azure resource... It can be assigned to one or more Azure service instances and is managed independently of the resources that use it." Because the scenario requires multiple Azure web apps to use the same identity, the only managed identity type that supports this sharing model is the user-assigned managed identity. This allows you to grant RBAC permissions once to the identity and then attach that same identity to several App Service instances, simplifying secretless access to Azure resources (Key Vault, Storage, SQL, etc.) and providing centralized lifecycle and rotation management. Certificates or generic service principals would reintroduce credential management, while a system-assigned identity cannot be shared across multiple apps. Therefore, a user- assigned managed identity is the correct choice.

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

Explanation:

Microsoft Entra Permissions Management is Microsoft's cloud infrastructure entitlement management (CIEM) solution delivered in the Microsoft Entra admin center, not in the Microsoft Purview compliance portal. Microsoft guidance describes it as a CIEM service that provides "centralized visibility, right-sizing, and governance of permissions across clouds" and is accessed and administered from the Entra portal under Permissions Management. The Purview compliance portal is used for compliance solutions such as Compliance Manager, Information Protection, DLP, eDiscovery, and Insider Risk-not CIEM-so statement
1 is No.
Permissions Management supports multicloud environments. Microsoft documentation states that it
"discovers, monitors, and manages permissions for identities and resources across Microsoft Azure, Amazon Web Services (AWS), and Google Cloud Platform (GCP)." It calculates a Permission Creep Index (PCI), surfaces excessive permissions, and recommends remediation across these clouds; therefore, using it to manage permissions in AWS is supported-statement 2 is Yes.
Regarding secure scores: Permissions Management focuses on entitlements (e.g., effective permissions, PCI, right-sizing actions). Microsoft Secure Score (and Identity Secure Score) are separate posture metrics exposed in Microsoft 365 Defender and Microsoft Entra ID, respectively. The Permissions Management blade does not present Microsoft Secure Score; instead, it shows CIEM-specific insights and PCI. Consequently, the claim that Secure Score can be reviewed from Permissions Management in the Entra admin center is No.
