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

SATA is a local disk interface standard for internal hard drives and is not a network-based external storage solution that TCS can integrate with for scalable shared storage.

CIFS is a network file-sharing protocol used to access storage, not a storage solution itself - it may serve as the transport mechanism to a NAS device but is not the storage solution.

NAS is the supported external storage solution for Cisco TCS, allowing the server to offload recorded content to a dedicated network storage device accessible via file-based protocols such as NFS or CIFS, scaling capacity well beyond internal disk limitations.

NFS is a network file-sharing protocol similar to CIFS - it is a method for accessing remote files, not a standalone storage solution that TCS integrates with as a storage system.
