Assuming the network supports all speeds, which of the following should an administrator use to get the MOST throughput?

CAT5 cabling supports up to 100 Mbps and cannot achieve gigabit speeds, making it a limiting factor for higher throughput.

A Gigabit NIC operates at 1000 Mbps (1 Gbps), offering significantly higher throughput compared to 10 Mbps or 100 Mbps NICs. To achieve the most throughput, all components in the network path, including the NIC, must support the highest desired speed.

A 10/100 full duplex NIC is limited to a maximum speed of 100 Mbps, which is ten times slower than a Gigabit NIC.

A 100 half duplex NIC can only send or receive data at 100 Mbps at any given time, not simultaneously, and is slower than a full-duplex 100 Mbps NIC and significantly slower than a Gigabit NIC.
