新しいサーバーに OS をインストールした後、管理者はサーバーにネットワーク接続がないことに気付きました。管理者がネットワーク ケーブルを確認すると、データが転送されているようです。次に確認する必要があるのは次のうちどれですか。
正解:B
If the network cable is functioning but there is no network connectivity, the next step would be to check theIPv4 options. This includes verifying that the server has a correct IP address, subnet mask, and gateway configuration. * IPv4 options (Answer B):Incorrect IP configuration is a common reason for network connectivity issues. * NIC firmware (Option A):Firmware issues are less likely if the NIC is detecting the cable and appears operational. * DHCP options (Option C):DHCP could be checked if automatic IP assignment is being used, but verifying IPv4 options manually is the first step. * Firewall options (Option D):Firewalls can block connectivity but should be checked after confirming IP settings. * DNS settings (Option E):DNS issues usually affect domain name resolution, not basic network connectivity.
