The Azure File Sync section of the Administering Windows Server Hybrid Core Infrastructure materials states that a sync group defines the topology for synchronization and “contains one cloud endpoint and one or more server endpoints.” A cloud endpoint is an Azure file share associated with a Storage Sync Service. The guidance also notes that “the Storage Sync Service and the storage account (file share) must reside in the same Azure region” and that “a single Azure file share can be the cloud endpoint for only one sync group.” In the scenario, SyncA is in West US, so only file shares in West US (for example, storage1\share1 or storage2\share2) are eligible. However, regardless of how many eligible shares exist, the exam guide is explicit: each sync group supports a maximum of one cloud endpoint. Additional endpoints in the group must be server endpoints on Windows Server volumes. Therefore, the maximum number of cloud endpoints you can use with GroupA is 1, which directly reflects the product’s architecture and the documented exam objective requirements.
