セキュリティ管理者は、間違った IP アドレスがネットワーク上のクライアントに割り当てられるのを防ごうとしています。これを防ぎ、ネットワークの運用を継続できる可能性が最も高いのは、次のうちどれですか?
正解:A
To prevent incorrect IP addresses from being assigned to clients on the network and allow the network to continue to operate, the security administrator should consider configuring DHCP (Dynamic Host Configuration Protocol) snooping on the switch. DHCP snooping is a security feature that is used to prevent unauthorized DHCP servers from operating on a network. It works by allowing the switch to monitor and validate DHCP traffic on the network, ensuring that only legitimate DHCP messages are forwarded to clients. This can help to prevent incorrect IP addresses from being assigned to clients, as it ensures that only authorized DHCP servers are able to provide IP addresses to clients on the network.
