SG0-001 · Question #455
Which of the following FC protocol layers is associated with the physical attributes of an interface and media?
The correct answer is A. FC-0. The FC-0 layer of the Fibre Channel protocol stack defines the physical attributes of the interface and media, including cabling, connectors, and signaling.

Why each option
The FC-0 layer of the Fibre Channel protocol stack defines the physical attributes of the interface and media, including cabling, connectors, and signaling.
FC-0, the Physical Layer, specifies the physical characteristics of the Fibre Channel connection, such as fiber optic or copper media, connectors, optical/electrical signaling, and data rates.
FC-1, the Encoding/Decoding Layer, is responsible for 8b/10b encoding, error detection, and link control word generation, not physical attributes.
FC-2, the Framing and Signaling Layer, defines the framing protocol, flow control, and services like login/logout within the Fibre Channel fabric.
FC-4, the Upper Layer Protocol Mapping, maps upper-layer protocols like SCSI or IP to the Fibre Channel frames.
