Zorluk: OrtaNetwork Cable Types and Connectors

An IT technician is configuring hardware inside a server room. The task requires connecting two network switches in adjacent equipment racks to form a 10 Gbps high-speed interconnect, as well as setting up a direct management connection to a legacy router's serial console port. Which of the following cabling and connector solutions should be selected for these requirements? (Select TWO.)

  1. Direct Attach Copper (DAC) twinaxial cable with integrated SFP+ transceivers for the inter-switch connectionCevap
  2. RS-232 serial cable terminated with a DB-9 connector for the router console port interfaceCevap
  3. C
    Category 5e Unshielded Twisted Pair (UTP) cable terminated with RJ-11 connectors for the 10 Gbps inter-switch link
  4. D
    RG-59 coaxial cable terminated with F-type connectors for the serial console management interface

Cevap

The correct selections are Direct Attach Copper (DAC) twinaxial cabling with integrated SFP+ transceivers for the 10 Gbps switch interconnect, and an RS-232 serial cable with a DB-9 connector for the router serial console interface.
Direct Attach Copper (DAC) twinaxial cabling with integrated SFP+ transceiver ends is designed for high-density, low-latency 10 Gbps interconnects across short distances such as adjacent server racks. For legacy device maintenance, serial console management ports transmit using the RS-232 communication standard over a standard 9-pin DB-9 connector.

Adım Adım Çözüm

1
Analyze the switch-to-switch 10 Gbps interconnect requirement.
Identify that short intra-rack or adjacent-rack 10 Gbps connections typically utilize Direct Attach Copper (DAC) twinaxial cabling fitted with SFP+ modules.
DAC cables offer an economical, power-efficient 10 Gbps solution over short distances (up to 7-10 meters).
2
Analyze the out-of-band serial management connection requirement for the legacy router.
Identify that legacy serial console management ports rely on RS-232 communication via DB-9 (DE-9) pin connectors.
DB-9 connectors are the standard legacy pinout interface for RS-232 serial maintenance ports.
3
Evaluate and discard incorrect choices based on bandwidth capability and physical connector standards.
Category 5e terminated with 4-wire RJ-11 telephone plugs lacks both the pin count and bandwidth needed for 10 Gbps. RG-59 coaxial cabling with F-type connectors is intended for video/CATV distribution rather than serial console control.
Physical connector forms (RJ-11, F-type) and cable categories (Cat 5e) must match operational bandwidth and protocol interfaces.

Anahtar Kavram

Selecting appropriate media standards (SFP+ DAC twinax vs. DB-9 RS-232) based on throughput limits, distance constraints, and device interface types.
