To manage on-premises data with Azure File Sync, which component acts as the bridge between on-premises servers and Azure File shares?

The component that acts as the bridge between on-premises servers and Azure File shares is the Storage Sync Service. This service enables the synchronization of files between your on-premises file servers and Azure, facilitating hybrid cloud scenarios. By using the Storage Sync Service, you can keep your data available on-premises while also leveraging the scalability, durability, and accessibility of Azure storage.

The Storage Sync Service essentially orchestrates data movement and keeps the on-premises file servers and Azure file shares in sync. It provides capabilities like tiering of data, backup, and disaster recovery, making it a vital component for organizations utilizing Azure File Sync.

The other components listed serve different roles within the Azure File Sync architecture. For example, a Cloud endpoint refers to the Azure file share that you want to sync your on-premises data to, while a Local File Sync Agent is a service that runs on the on-premises servers to communicate with the Storage Sync Service. However, it is the Storage Sync Service that ultimately manages and orchestrates the synchronization process, making it the correct answer in this scenario.
