E10-001 Question #12: Real Exam Question with Answer & Explanation

The correct answer is A. Encoding and decoding. FC-1 Layer: It defines how data is encoded prior to transmission and decoded upon receipt. At the transmitter node, an 8-bit character is encoded into a 10-bit transmission character. This character is then transmitted to the receiver node. At the receiver node, the 10-bit charac

Explanation

FC-1 Layer: It defines how data is encoded prior to transmission and decoded upon receipt. At the transmitter node, an 8-bit character is encoded into a 10-bit transmission character. This character is then transmitted to the receiver node. At the receiver node, the 10-bit character is passed to the FC-1 layer, which decodes the 10-bit character into the original 8-bit character. FC links with speed 10 Gbps and above use 64-bit to 66-bit encoding algorithm. This layer also defines the transmission words such as FC frame delimiters, which identify the start and end of a frame and primitive signals that indicate events at a transmitting port. In addition to these, the FC- 1 layer performs link initialization and error recovery. EMC E10- 001 Student Resource Guide. Module 5: Fibre Channel Storage Area Network (FC SAN)
