SG0-001 · Question #190

Which of the following are true when comparing iSCSI and CIFS protocols? (Select TWO).

The correct answer is B. Server can be booted from iSCSI E. Storage appears as a local disk using iSCSI. iSCSI allows servers to boot from remote storage and presents that storage as a local disk, providing block-level access over IP networks.

Why each option

iSCSI allows servers to boot from remote storage and presents that storage as a local disk, providing block-level access over IP networks.

AiSCSI was developed mainly for databases

While iSCSI is well-suited for databases due to its block-level access, it was developed as a general-purpose block storage protocol for IP networks, not primarily or solely for databases.

BServer can be booted from iSCSICorrect

iSCSI (Internet Small Computer System Interface) enables a host server to boot remotely from a storage array over a standard IP network, a process known as iSCSI boot or boot from SAN.

CiSCSI is used in Fibre Channel

iSCSI encapsulates SCSI commands over TCP/IP and operates over Ethernet networks, making it distinct from Fibre Channel, which uses its own specialized protocol and infrastructure.

DCIFS is commonly used in UNIX

CIFS (Common Internet File System), now largely succeeded by SMB, is predominantly used in Windows environments for file sharing; NFS (Network File System) is more commonly associated with UNIX/Linux systems.

EStorage appears as a local disk using iSCSICorrect

iSCSI provides block-level access to storage, meaning that the remote storage device appears to the operating system of the server as if it were a locally attached hard drive or disk.
