Question

Organizations tend to follow a single cabling standard, known as the TIA (Telecommunications Industry Association)/EIA (Electronics Industries Alliance)-568 Commercial Building Wiring Standard or structured cabling. Which of the following statements regarding structured cabling are INCORRECT (More than one statement applies)?

a. Structured cabling is based on a hierarchical design and assumes a network is setup in a star topology.
b. The IDF (Intermediate Distribution Frame) is the centralized point of interconnection for an organization’s LAN (Local Area Network), CAN (Campus Area Network), or WAN (Wide Area Network).
c. The horizontal cabling connects workstations to the closest data room. The maximum allowable distance for horizontal wiring is 90m.
d. The work area encompasses workstations, printers, and other network devices, and all the patch cables, wall jacks, and horizontal cabling necessary to connect these devices to a data room.

Answer 1

Structured cabling is based on a hierarchical design and assumes a network is setup in a star topoloy. The IDF is the centralized point of interconnection for an organization's LAN, CAN, or WAN. The maximum allowable distance for horizontal wiring in structured cabling is 100 meters. Option c is correct..

Step-by-step explanation:

The question is asking us to identify the incorrect statements about structured cabling. Let's go through each statement one by one: a. Structured cabing is based on a hierarchical design and assumes a network is setup in a star topology. This statement is correct. Structured cabling does follow a hierarchical design and typically uses a star topology. b. The IDF (Intermediate Distribution Frame) is the centralized point of interconnection for an organization’s LAN (Local Area Network), CAN (Campus Area Network), or WAN (Wide Area Network). This statement is also correct. The IDF acts as a central point for interconnecting different networks within an organization.

c. The horizontal cabling connects workstations to the closest data room. The maximum allowable distance for horizontal wiring is 90m. This statement is incorrect. The maximum allowable distance for horizontal wiring in structured cabling is 100 meters.d. The work area encompasses workstations, printers, and other network devices, and all the patch cables, wall jacks, and horizontal cabling necessary to connect these devices to a data room. This statement is also correct. The work area includes all the necessary components to connect devices to the data room.Based on this analysis, the incorrect statement is c. The maximum allowable distance for horizontal wiring in structured cabling is 100 meters, not 90 meters.
