A server technician needs to connect two servers with gigabit NICs without MDI-X in order to transfer files between them and is unable to locate a switch with gigabit ports. Which of the following…

Rollover (console) cables use a full pin reversal pattern intended for out-of-band console access to networking gear and are not designed to carry Ethernet data traffic.

When connecting two like devices (server to server) and neither NIC supports Auto-MDIX, a crossover cable is mandatory to swap the transmit and receive pairs so each side's TX connects to the other's RX. CAT6 is rated for 1000BASE-T (Gigabit Ethernet), which matches the gigabit NICs and delivers the fastest possible transfer rate in this direct-connect scenario. A CAT6 crossover therefore satisfies both the wiring requirement and the bandwidth requirement simultaneously.

A CAT6 straight-through cable connects TX to TX on both ends, which requires Auto-MDIX to resolve the conflict; without MDI-X support the link would fail to establish.

CAT5 cable is rated only for 100BASE-TX (100 Mbps), so it cannot achieve gigabit speeds, and it is also a straight-through type that would fail without MDI-X support.
