Explanation:
Services: Exchange Online and SharePoint Online only
Retention period: 1 year
The correct dropdown selection is Exchange Online and SharePoint Online only. Microsoft 365 Backup supports backup and recovery for OneDrive, SharePoint, and Exchange Online workloads. From the services listed in this question, Exchange Online and SharePoint Online are the only supported services. Microsoft Entra is not a Microsoft 365 Backup workload because it is an identity and directory platform, not a content workload protected by Microsoft 365 Backup. Microsoft Teams is also not selected as a separate backup service. Teams files are stored in SharePoint or OneDrive, but Microsoft 365 Backup does not list "Teams" as an independent backup workload. Microsoft's backup policy documentation also separates backup policy configuration into SharePoint, Exchange, and OneDrive tabs, reinforcing that those are the protected workload categories.
The longest available retention period is 1 year. Microsoft's Microsoft 365 Backup FAQ states that when backed-up OneDrive or Exchange content is removed from the backup policy or the user is deleted, the backup is retained for one year from the date the backup was created. Therefore, among the given retention choices, the correct maximum is 1 year, not 5 or 10 years.
