What is the default setting for duplex and speed on a switch port?

• A. Half-duplex only
• B. Fixed speed settings
• C. Auto-negotiation
• D. Full-duplex only

Answer: (C)

The default setting for duplex and speed on a switch port is auto-negotiation. This means that a switch port can automatically negotiate the best possible speed and duplex settings with the connected device, such as a computer or another switch. When a device is connected, the switch and the device will exchange information to determine the highest speed and the correct duplex mode that both can support. Auto-negotiation allows for greater flexibility and can help to minimize configuration errors that might arise from manually setting the speed and duplex mode. It is particularly important in networks where devices from different manufacturers or models might be connected, ensuring compatibility and optimal performance. In contrast, options that suggest fixed speed settings or specific duplex types would require manual configuration and might lead to mismatched settings if not coordinated with the connected device, potentially resulting in connectivity issues.
