Which component provides flexible options for storing video and audio using a combination of network ? attached storage, direct attached storage, and SAN storage deployments?

The ISR Video Management and Storage Module is integrated into ISR routers for branch-level recording and does not provide flexible multi-storage-type deployments.

The Transcoding and Encoding Server handles video format conversion and stream encoding, not storage architecture or deployment.

The Cisco Video Surveillance Storage System is specifically designed to provide flexible, scalable storage for video and audio data by supporting a combination of NAS, DAS, and SAN architectures. This allows organizations to mix storage types based on capacity, cost, and performance requirements. No other Cisco video surveillance component is designed to unify all three storage deployment models in this way.

The Media Server manages video recording and streaming workflows but does not provide the combined NAS, DAS, and SAN storage flexibility described.
