カスタム ホスト ファイルを持つユーザーは、小規模オフィス ネットワーク上でローカルにホストされているサイトに接続するのが困難です。技術者は、ユーザーのコンピュータからサーバーのホスト名に ping を送信できません。技術者がサーバー上で確認すべきことは次のうちどれですか?
正解:A
A custom hosts file is a file that maps hostnames to IP addresses, allowing the user to access websites or servers by their names instead of their numerical addresses. For example, a user can add a line like 192.168.1.100 myserver.local to their hosts file and then access the server by typing myserver.local in their browser. However, this method only works if the IP address of the server does not change. If the server is configured with a dynamic IP address, which means it can be assigned a different IP address by the network router or DHCP server, then the hosts file entry will become invalid and the user will not be able to connect to the server by its hostname. Therefore, the technician should ensure that the server is configured with a static IP address, which means it has a fixed and permanent IP address that does not change. This way, the hosts file entry will always point to the correct IP address of the server and the user will be able to ping the server hostname from their computer.
