ある銀行は、オンライン ビデオ サービスをストリーミングするために新しいスマート TV を設置しましたが、スマート TV は支店の Wi-Fi に接続できませんでした。次の日。技術者はテレビを Wi-Fi に接続できましたが、同時に銀行のラップトップがネットワーク アクセスを失いました。最も考えられる原因は次のうちどれですか?
正解:A
DHCP scope exhaustion is the situation when a DHCP server runs out of available IP addresses to assign to clients. DHCP stands for Dynamic Host Configuration Protocol, which is a network protocol that automatically assigns IP addresses and other configuration parameters to clients on a network. A DHCP scope is a range of IP addresses that a DHCP server can distribute to clients. If the DHCP scope is exhausted, new clients will not be able to obtain an IP address and connect to the network. This can explain why the smart TV was not able to connect to the branch Wi-Fi on the first day, and why the bank laptop lost network access on the next day when the TV was connected. The technician should either increase the size of the DHCP scope or reduce the lease time of the IP addresses to avoid DHCP scope exhaustion.
