A video engineer must integrate a storage solution with Cisco TCS that supports external storage. Which solution must be used?

NAS (Network Attached Storage) is a dedicated file-level storage appliance connected via a network that Cisco TCS is designed to integrate with for external content and recording storage. By pointing TCS to a NAS device, engineers can expand storage capacity beyond internal drives and centralize media files on a shared, scalable network resource.

CIFS (Common Internet File System) is a network file-sharing protocol, not a storage solution - it describes how files are accessed over a network rather than the physical or logical storage device itself.

NFS (Network File System) is likewise a file access protocol rather than a storage solution - it defines the method for mounting and accessing remote file systems, not the storage device.

SATA (Serial ATA) is a local disk interface standard used for internal drive connections within a server and does not provide any form of external or networked storage capability.
