Priya is running a new data drop from a switch to a workstation that must support a 1 Gbps Ethernet link. She needs to terminate the twisted-pair cable with the correct plug. Which connector should she crimp onto the cable?
- ARJ-11, the six-position plug commonly used to terminate copper runs feeding desktop network adapters
- BRJ-45, the eight-position plug that terminates the four twisted pairs of an Ethernet patch or drop cable Correct
- CF-type, the threaded coaxial connector used to terminate the run and land it on the workstation adapter
- DDB-9, the nine-pin serial connector often crimped onto twisted-pair runs feeding network ports
Why A is wrong: RJ-11 is tempting because it looks like a smaller Ethernet plug and uses the same crimp tooling, but it is a 6-position telephone connector and will not carry a Gigabit Ethernet link.
Why B is correct: RJ-45 is an 8P8C connector that lands all four pairs, which Gigabit Ethernet requires, making it the correct plug for a 1 Gbps drop.
Why C is wrong: F-type is plausible from cable-modem work, but it terminates 75-ohm coaxial cable, not twisted pair, so it cannot terminate an Ethernet drop.
Why D is wrong: DB-9 is a legacy serial connector for consoles and peripherals, not a crimp-on Ethernet plug, so it cannot terminate a network drop.
