What is the MOST likely reason for a server showing an amber link light on the switch port after a new connection?

• A. A faulty network cable
• B. A misconfigured NIC on the server
• C. Incompatible switch model
• D. Overloaded network traffic

Answer: (B)

The presence of an amber link light on a switch port is often indicative of issues related to the configuration or health of the connection. In this scenario, a misconfigured Network Interface Card (NIC) on the server is likely the most relevant reason for the amber link light. When a NIC is misconfigured, it may not correctly negotiate the speed and duplex settings with the switch, leading to link issues. Such a configuration problem results in the switch being unable to establish a proper communication link, which can manifest as an amber light—indicating a failure in achieving optimal connection parameters. Moreover, when a NIC is improperly set up, it may also affect other settings such as VLAN tagging or other network-related configurations, further contributing to communication failures. This deepens the impact on network performance and connectivity, which is what the amber light is signaling. A faulty network cable could also cause connectivity issues but would more commonly lead to a link-light being off rather than just amber. Similarly, the choice of switch model typically does not cause an amber light unless there is a specific compatibility issue that needs to be acknowledged, which is less common. Lastly, while overloaded network traffic can lead to performance degradation, it usually does not cause the link light to change from green
