Auto-negotiate mode is to obtain the maximum interface rate and operating mode, the network administrator configures all Ethernet interface rates of a working switch to 10OMbps, and the operating mode is configured as Full-duplex, when a network card is configured After the auto-negotiate workstation is connected to the switch, the negotiation result is that the interface rate is 10OMbps and the working mode is half-duplex, which of the following explanations is the most reasonable for this phenomenon?

• A.At higher port rates and operating modes, the workstation's network interface card cannot be configured as auto-negotiate
• B.Port rate negotiation is negotiated through the initial port sending FLP , and the operating mode is not negotiated through FLP
• C.Auto-negotiation is not configured on the switch, resulting in the switch not being able to send FLP messages to the workstation, causing the workstation to set its own operating mode to Half-duple
• D.The problem is on the workstation's NIC, mostly due to the aging of the NIC driver on the workstation , which causes the workstation NIC to learn the interface rate and operating mode configured on the switch
• E.STP initializes the port into the blocking state, causing auto-negotiation to fail, so the port should be configured as an edge port
