The management IP address is the address assigned to the storage device’s management interface for administration. It’s the steady, admin-only address you use to log in and configure the device (via GUI or CLI) without mixing it with data traffic. In this setup, the storage device’s management interface has been allocated 192.168.5.12 on the 192.168.5.0/24 subnet. That specific address is reserved for management, ensuring administrators can reach the device reliably for setup and ongoing management. Other addresses in the same subnet are typically used for other purposes (such as a gateway or other devices), so they aren’t intended for managing the storage device.

IP SAN data transmission relies on moving SCSI commands over IP networks by using the iSCSI protocol. iSCSI wraps SCSI commands and responses in TCP segments, so they can travel over Ethernet or other IP networks and be reassembled at the destination. This is why the true statement is that IP SAN uses iSCSI for data transmission. The Fibre Channel protocol is a separate transport used by FC SANs, not the IP-based path. Bridging an IP SAN to an FC SAN without any additional protocols isn’t feasible, since IP and FC use different transport methods and require gateways or bridges to interoperate. And IP SAN does encapsulate SCSI commands via iSCSI, so saying it cannot encapsulate SCSI commands is incorrect.

Access to a storage device’s management interface should be protected with encrypted channels so credentials and configuration data aren’t exposed. Secure management uses SSH for CLI access and HTTPS for web interfaces. FTP, on the other hand, is designed for file transfers and sends data and logins in clear text by default, which makes it insecure for administering a device. Because of this lack of encryption, FTP is not typically used for secure management access.

The main idea is how data is organized and accessed in distributed storage: by blocks, files, or objects. A file storage service is built around a traditional file system model, offering a hierarchical structure of directories and files and enabling file-level operations through standard file protocols like NFS or SMB. This makes it ideal for shared folders, user home directories, and applications that expect a familiar file-system interface. Block storage provides raw blocks to a client and relies on a separate file system inside, which is different from offering a direct file-based service. Object storage stores data as objects with metadata in a flat namespace, optimized for scalability and unstructured data, but it doesn’t provide a traditional file hierarchy. HDFS storage is a distributed file system used in Hadoop ecosystems, a specialized implementation rather than a general file storage service option. So the option that represents a file-based storage service is the one that gives a hierarchical file system interface.
