Incorrect Answers:
A: A Storage Area Network (SAN) is a high-speed subnetwork of shared storage devices.
B: All storage devices included in a Storage Area Network (SAN) is available to all servers on the local area network and clients access the storage devices through the servers on the LAN C: A Storage Area Network (SAN) has special switch mechanisms which allow SANdevices to communicate with each other outside of standard network infrastructure and allows for the backup of all data on the SAN outside of standard network infrastructure.
