技術者がサーバーのセカンダリ NIC を別のネットワークに接続しています。技術者はケーブルをスイッチに接続しましたが、NIC にリンク ライトが表示されません。技術者は、ネットワークまたは物理接続に問題がないことを確認します。技術者が次に実行すべきことは次のうちどれですか?
正解:C
The next thing that the technician should perform is to enable the port on the server. A port is a logical endpoint that identifies a specific service or application on a network device. A port can be enabled or disabled depending on whether the service or application is running or not. If a port is disabled on a server, it means that the server cannot send or receive any network traffic on that port, which can prevent communication with other devices or services that use that port. In this case, if port 389 is disabled on the server, it means that the server cannot use LDAP to access or modify directory services over a network. To resolve this issue, the technician should enable port 389 on the server using commands such as netsh or iptables.
