E The most likely answer is E. Reseat the laptop in the docking station. The IPv4 address of 169.254.0.9 indicates that the laptop is using an Automatic Private IP Address (APIPA), which means that it could not obtain a valid IP address from the DHCP server on the network1. This could be caused by a physical or logical problem with the network adapter, the cable, the docking station, or the network itself2.

One of the possible solutions is to reseat the laptop in the docking station, which means to remove it and insert it again, making sure that it is properly aligned and connected. This can help fix any loose or faulty connections between the laptop and the docking station, and between the docking station and the network cable3. Reseating the laptop can also trigger a new DHCP request and renew the IP address4. Other possible solutions include resetting the network adapter, replacing the network cable, rebooting the DHCP server, or restarting the laptop in safe mode. However, these are less likely to be effective than reseating the laptop, as they involve more steps and may not address the root cause of the problem234. Replacing the laptop is an extreme and unnecessary measure, as there is no evidence that the laptop itself is faulty.

The best next step would be to C. Reset the network adapter. The IP address 169.254.0.9 is a link-local address, which is automatically assigned to a device when it fails to obtain an IP address from a DHCP server. This indicates that the network adapter is not communicating properly with the DHCP server. Resetting the network adapter can often resolve connectivity issues by refreshing the network settings and forcing the device to request a new IP address from the DHCP server. GG

E. Reset the laptop in the docking station. Explanation: Reset the laptop in the docking station: This step ensures that the laptop is properly seated in the docking station and that all connections are secure. A loose connection can cause the NIC to not function correctly, leading to issues like the 169.254.x.x IP address, which indicates that the laptop is not receiving an IP address from the DHCP server.

Selected Answer: C
Given the symptoms described (laptop unable to access the network, IPv4 assignment of 169.254.0.9, no link or activity lights on the NIC), the technician should consider the following steps: C. Reset the network adapter. Explanation: The assignment of an IPv4 address in the 169.254.x.x range typically indicates that the laptop was unable to obtain an IP address from the DHCP server. This range is reserved for Automatic Private IP Addressing (APIPA) when a device cannot obtain a valid IP address. The absence of link or activity lights on the NIC suggests a potential hardware or connection issue.
