組織には、DHCP プールを使用するネットワーク IP 範囲が 192.168.1.0/28 のゲスト ネットワークがあります。ある訪問者は、接続に問題があり、静的 IP アドレスを設定できなかったと報告しました。このアクションの後、別の訪問者が断続的な接続の問題を報告しました。最も考えられる理由は次のうちどれですか?
正解:B
Explanation A duplicate IP address occurs when two devices on the same network have the same IP address assigned to them. This can cause intermittent connection issues, as the network devices may not be able to distinguish between the two conflicting devices. A duplicate IP address can be caused by a visitor manually configuring a static IP address that is already in use by another device on the guest network. The network IP range of 192.168.1.0/28 has only 14 usable host addresses, so the chances of a duplicate IP address are higher than a larger network.
