A network field technician is tasked with wiring an expansion link from an automated industrial manufacturing floor—known for severe electromagnetic interference (EMI) from heavy machinery—to a network switch situated inside a ceiling return air plenum space. Concurrently, the technician must establish a direct serial connection from an out-of-band management appliance to a legacy router's dedicated serial console port. Which of the following cabling standards, jack types, and outer jacket ratings must the technician deploy to meet all technical and safety requirements? (Select TWO.)
- Shielded Twisted Pair (STP) Category 6a cabling with a plenum-rated (CMP) jacket, terminated with RJ45 connectors for the 10 Gbps industrial network run.Cevap
- An RS-232 serial cable terminated with a DB9 connector to interface directly with the legacy router's serial management console port.Cevap
- CUnshielded Twisted Pair (UTP) Category 6 cabling with a riser-rated (CMR) jacket, terminated with RJ11 connectors for the 10 Gbps industrial network run.
- DMultimode fiber-optic cable terminated with F-type screw-on connectors to establish the serial console connection.
Cevap
The correct selections are Shielded Twisted Pair (STP) Category 6a cabling with a plenum-rated (CMP) jacket terminated with RJ45 connectors, and an RS-232 serial cable terminated with a DB9 connector.
Category 6a STP CMP cable with RJ45 connectors fulfills the 10 Gbps speed requirement, protects against severe industrial EMI, complies with plenum building safety regulations, and uses standard Ethernet pinouts. For out-of-band serial management on legacy devices, RS-232 over a DB9 connector is the standard physical pin configuration.

Anahtar Kavram
Twisted-pair cable specifications (Cat 6a STP vs UTP), jacket fire safety ratings (CMP vs CMR), Ethernet connectors (RJ45), and serial management ports (DB9/RS-232).
