What is the pin configuration used by a firewall to receive data in a FastEthernet connection?

• A. 1 and 2
• B. 3 and 6
• C. 7 and 8
• D. 4 and 5

Answer: (B)

In a FastEthernet connection, which typically uses an RJ-45 connector, the pin configuration for receiving data is through pins 3 and 6. This configuration is part of the Ethernet standard, where pin 3 is used for the second pair of wires (transmit pair) in a crossover cable, allowing the device to receive data from another device, and pin 6 is used for the corresponding receiving function. While other pins are utilized in networking, pins 1 and 2 are commonly associated with transmitting data, and pins 4 and 5 may be used in power over Ethernet (PoE) applications or for other signaling purposes. However, for standard data reception specifically in FastEthernet setups, pins 3 and 6 are designated for this task. Understanding this pin configuration is crucial for proper network setup and troubleshooting, ensuring that devices can communicate effectively on an Ethernet network.
