Which of the following storage technologies connects by TCP/IP and can slow down network traffic?

A SAN (Storage Area Network) typically uses Fibre Channel or iSCSI (often on dedicated networks/VLANs) and operates at the block level, usually on its own high-speed network to avoid impacting general network traffic.

An optical jukebox stores and manages optical discs for archival purposes and is not typically involved in high-volume, real-time data access that would significantly slow down a general-purpose network.

Network Attached Storage (NAS) devices connect to a network via standard Ethernet and use TCP/IP to provide file-level data access to multiple clients. Since NAS shares the same network infrastructure with other applications and services, heavy data access to the NAS can consume significant network bandwidth, potentially slowing down other network traffic.

A tape library is primarily used for long-term data backup and archival, connecting via specialized interfaces and not typically for continuous, high-volume access over a general TCP/IP network.
