RJ45 ポートを備えたエンドポイント デバイスを ST ポートを備えたネットワーク デバイスに接続する場合、次のどれが必要ですか?
正解:A
The device that is required when connecting an endpoint device with an RJ45 port to a network device with an ST port is a media converter. A media converter is a device that converts signals between different types of media, such as copper and fiber. An RJ45 port is used for twisted-pair copper cables, while an ST port is used for fiber-optic cables. A media converter allows these two types of cables to interconnect and communicate.
