Joe a network administrator is setting up a virtualization host that has additional storage
requirements. Which of the following protocols should be used to connect the device to the
company SAN? (Select Two)
A.
Fibre channel
B.
SCP
C.
iSCSI
D.
FDDI
E.
SSL
• A storage area network (SAN) is a Computer network which provides access to consolidated, block level data storage. SANs are primarily used to enhance storage devices, such as disk arrays and tape libraries, accessible to servers so that the devices appear to the operating system as locally attached devices. A SAN typically is its network of storage devices not accessible through the local area network (LAN) by other devices.
• Transfer of data between storage devices, such as for backup, happen behind the servers, and are meant to be transparent. While in a NAS architecture data is transferred using the TCP and IP protocols over Ethernet, distinct protocols were developed for SANs, such as Fibre Channel. Therefore SANs have often their own network and storage devices, which have to be bought, installed and configured. This makes SANs inherently more expensive than NAS architectures.
• When SANs were first built fibre channel had to be implemented over copper cables, these days multimode optical fibre cables are used in SANs
• On top of the Fibre Channel-Switched Protocol is often the serialised Small Computer Systems Interface (SCSI) protocol, implemented in servers and SAN storage devices. It allows software applications to communicate, or encode data, for storage devices
So A & C are indeed the correct answers

please note that A_ Fibre Channel, refers to the Protocol of the same name:
Fibre Channel Protocol (FCP) is the SCSI interface protocol utilising an underlying Fibre Channel connection. The Fibre Channel standards define a high-speed data transfer mechanism that can be used to connect workstations, mainframes, supercomputers, storage devices and displays.
