A network technician is auditing legacy and modern cabling infrastructure across an enterprise facility. Match each physical connector type on the left to its corresponding characteristic or primary deployment use-case on the right.
- DB9 ConnectorLegacy 9-pin serial interface commonly used for direct terminal console access to networking equipment.
- ST ConnectorFiber optic connector featuring a round, bayonet-style twist-lock mechanism and ceramic ferrule.
- RJ45 Connector8-position 8-contact (8P8C) modular connector used to terminate unshielded twisted-pair Ethernet cables.
- USB-C Connector (Thunderbolt 4)Reversible 24-pin interface supporting up to 40 Gbps throughput, DisplayPort alternate mode, and PCIe tunnel signaling.
Cevap
DB9 matches the legacy 9-pin serial interface for console access; ST matches the bayonet-style twist-lock fiber optic connector; RJ45 matches the 8-position modular connector for twisted-pair Ethernet; USB-C (Thunderbolt 4) matches the reversible 24-pin multi-protocol interface supporting 40 Gbps and PCIe tunneling.
Each connector type is paired correctly based on physical construction and network deployment role: DB9 is a 9-pin serial connector for console administration; ST is a twist-lock bayonet connector for fiber optics; RJ45 is an 8P8C modular connector for twisted-pair copper Ethernet; USB-C (Thunderbolt 4) is a 24-pin reversible connector supporting high-speed PCIe tunneling and video signals.
