CompTIA Network+ N10-006 Q35

A technician is connecting a NAS device to an Ethernet network. Which of the following technologies will be used to encapsulate the frames?

A. HTTPS
B. Fibre channel
C. iSCSI
D. MS-CHAP

Correct Answer: C
Section: Network architecture

Explanation:
A NAS or a SAN will use either iSCSI or Fiber Channel. In this question, the NAS is connected to an Ethernet network. Therefore, iSCSI will most likely be used (Fiber Channel over Ethernet (FCoE) can be used but is less common). ISCSI means Internet SCSI.
ISCSI uses TCP (Transmission Control Protocol) which enables it to be used over TCP/IP networks such as Ethernet. For Fiber channel, a separate Fiber Channel network would be required unless FCoE is used.
