会社のラップトップは、統合 NIC を備えたドッキング ステーションを使用していますが、DHCP を使用して有線 SOHO ネットワークにアクセスできません。技術者が ipconfig を実行すると、ラップトップに IPv4 が割り当てられていることを発見しました。
169.254.0.9。NIC にはリンクがなく、アクティビティ ライトも点灯しません。技術者が次に行うべきことは次のうちどれですか?
正解:E
Explanation
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.
