サーバー管理者は、サーバー上のネットワークを 40 Gbps にアップグレードする任務を負っています。カードを取り付けた後、管理者は次のどのコネクタを使用する必要がありますか?
正解:A
QSFP+ (Quad Small Form-factor Pluggable Plus) connectors are used in high-density, high-speed networking solutions such as 40 Gigabit Ethernet (40GbE) interfaces. When upgrading a server's network to 40Gbps, QSFP+ is the appropriate choice due to its capability to support such high-speed data transfer rates. 10 GigE, SFP, and SFP+ connectors are used for lower speed connections (10Gbps and below for SFP+ and 10 GigE, and even less for SFP), making them unsuitable for a 40Gbps network upgrade.
