Topic #: 1
A storage administrator is configuring a new array to provide storage to a virtual cluster. The array has a built-in backup agent to allow data that is stored on the array to be backed up. The storage administrator wants the virtual cluster to use a file-based storage protocol so the backup agent can just back up the files that change and not the whole data store. Which of the following storage protocols should the administrator use?
Different storage protocols operate at different levels (file-based vs. block-based):
iSCSI (Internet Small Computer Systems Interface) is a block-level protocol, meaning that the storage appears as raw disk space to the operating system. Backups would require copying entire blocks, rather than specific files.
FC (Fibre Channel) is another block-level protocol used in high-performance SANs. It does not support file-based storage natively.
FCoE (Fibre Channel over Ethernet) extends FC over Ethernet but still functions as a block-based storage solution.
NFS (Network File System) is a file-based storage protocol, making it the best option. It allows direct access to files, which enables backup software to back up only modified files instead of the entire block device.
Since the administrator requires a file-based storage protocol to ensure efficient incremental backups, NFS is the correct choice.
