ARX will detect any modification to a file on the second tier because all clients are being _______ by the ARX to get to the storage.

ARX does not physically move files during a live client I/O operation; file migration between tiers is a policy-driven background process, not the mechanism for detecting modifications.

ARX does not copy files to intercept access; it transparently forwards and intercepts I/O operations at the network level without duplicating data.

ARX functions as a transparent network proxy, intercepting all client file requests before they reach the underlying storage tier. Because every client is routed through the ARX device, it can inspect and track all read and write operations regardless of which storage tier holds the file, allowing it to detect modifications, enforce policies, and perform data management transparently.

Backup is not how ARX monitors file changes; ARX intercepts live I/O by sitting inline as a proxy between clients and storage systems.

Deletion is not the mechanism ARX uses to detect or track modifications; ARX proxies all file operations without altering or removing data.
