管理者は、ネットワーク セグメント上のすべてのデバイスの IPv6 アドレスと MAC アドレスを定期的に記録するスクリプトを作成しています。次のスイッチ機能のうち、このタスクを支援するために使用される可能性が最も高いのはどれですか?
正解:B
Explanation
Short Explanation: The switch feature that is most likely to be used to assist with logging IPv6 and MAC addresses of devices on a network segment is Neighbor Discovery Protocol (NDP). NDP is used by IPv6 to discover and maintain information about other nodes on the network, including their IPv6 and MAC addresses.
By periodically querying NDP, the administrator can log this information for auditing purposes.
