NS0-157 · Question #243
Which five protocols are supported by Data ONTAP 8.1 Cluster-Mode or later? (Choose five)
The correct answer is A. CIFS B. FC D. FCoE F. iSCSI G. NFS. Data ONTAP 8.1 Cluster-Mode supports five client-facing storage protocols - CIFS, FC, FCoE, iSCSI, and NFS - while FCIP and iFCP are network interconnect technologies, not supported client protocols.

Why each option
Data ONTAP 8.1 Cluster-Mode supports five client-facing storage protocols - CIFS, FC, FCoE, iSCSI, and NFS - while FCIP and iFCP are network interconnect technologies, not supported client protocols.
CIFS (SMB) is a supported NAS protocol in Data ONTAP 8.1 Cluster-Mode, enabling Windows-compatible file sharing across the cluster namespace.
Fibre Channel is a supported SAN block protocol in Data ONTAP 8.1 Cluster-Mode, allowing FC-attached hosts to access LUNs on the storage system.
FCIP is a WAN tunneling technology used to extend FC SANs over IP networks between geographically separated sites, not a client-facing storage access protocol supported in Data ONTAP Cluster-Mode.
FCoE (Fibre Channel over Ethernet) is supported in Data ONTAP 8.1 Cluster-Mode, enabling FC block storage traffic to be carried over converged Ethernet network infrastructure.
iFCP is a gateway protocol for interconnecting Fibre Channel SANs over IP fabrics at the fabric level, not a direct client data access protocol supported in Data ONTAP 8.1 Cluster-Mode.
iSCSI is a supported IP-based SAN block protocol in Data ONTAP 8.1 Cluster-Mode, enabling block storage access to hosts over standard TCP/IP networks.
NFS is a supported NAS protocol in Data ONTAP 8.1 Cluster-Mode, providing Unix/Linux-compatible network file system access to clients.
