Microsoft Entra ID supports soft deletion of Microsoft 365 groups, retaining their directory objects and associated service resources for a defined recovery period.

First selection: Group3 only.

The original examination answer reflects the established Microsoft 365 group restoration capability. Microsoft 365 groups can be restored with their membership, Exchange mailbox, SharePoint site, calendar, and supported associated resources.

Traditional distribution groups and mail-enabled security groups do not use the same Microsoft Entra Microsoft 365 group soft-delete recovery workflow.

Second selection: 30 days.

Microsoft maintains deleted Microsoft 365 groups in a recoverable state for 30 days. Administrators can restore them during that period by using the Microsoft Entra admin center or supported PowerShell commands.

Current Microsoft documentation correction: Microsoft now also supports restoration of cloud security groups through a public-preview capability. Therefore, Group1 may also be recoverable if it is a cloud security group in a supported tenant.

The exhibit identifies Group1 only as Security and does not specify whether it is cloud-managed or synchronized from Active Directory.

As a result, Group3 only is the intended historical answer, but it is no longer unconditionally correct under current Microsoft documentation. The 30-day retention period remains correct.
