展示を参照してください。 エンジニアは、インターフェイス Fa 1/0/7 でコマンド no spaning-tree bpduguard enable を入力しました。Fa 1/0/7 に対するこのコマンドの効果は何ですか?
正解:A
The command "no spanning-tree bpduguard enable" on interface Fa 1/0/7 disables the BPDU Guard on that specific interface. However, if the interface is already in an err-disabled state due to a previous detection of BPDU while BPDU Guard was enabled, it will remain in that state until manually recovered. The manual recovery involves entering the "shutdown" followed by the "no shutdown" command in the interface configuration mode to bring it back up.
