A network infrastructure technician is preparing physical layer deployments across various environments in an enterprise environment. Match each cable and connector combination on the left with its appropriate deployment scenario on the right.
- Single-mode fiber optics with LC connectorsInterconnecting network switches located in two separate campus buildings 2 kilometers apart requiring minimal signal attenuation and high bandwidth
- Shielded Twisted Pair (STP) Category 6a with RJ45 connectorsDeploying a 10 Gbps Ethernet run across an active industrial manufacturing floor subject to severe electromagnetic interference (EMI)
- RG-6 Coaxial cable with F-type connectorsConnecting a broad-band cable modem to an ISP wall outlet via a threaded, screw-on physical interface
- RS-232 Serial cable with DB-9 connectorsEstablishing an out-of-band management console connection directly between a terminal laptop and a network switch
Cevap
Single-mode fiber optics with LC connectors matches building-to-building 2 km interconnections; Shielded Twisted Pair Cat 6a with RJ45 matches 10 Gbps industrial deployments with EMI; RG-6 Coaxial with F-type matches broad-band cable modem connections; RS-232 Serial with DB-9 matches switch console management connections.
Each cable type is specialized: Single-mode fiber with LC connectors offers low attenuation for multi-kilometer inter-building links; STP Cat 6a provides 10 Gbps speed while shielding signals against EMI on factory floors; RG-6 coaxial with threaded F-type connectors delivers ISP broadband signals securely; and DB-9 serial cables support direct console access to infrastructure equipment.
