Which of the following cabling methods connects workstations to the closest data rooms?

Answer:

2.1 

Establishing the network connection below can be used:

A stack provides the network solution that makes a stack of two or more switches. Once they are stacked then they work as a single device. With this facility, there will be several ports available for the connection. These ports can be used to connect the router. 

Suppose there are a large number of wired computers, cell phones, printers, and other wireless devices connected to the network. Let’s say 30 switches, and a couple of core router gets connected with the star topology.  Assume there is a requirement for the server with 10 blades that is 256 GB of memory. We can make the server connection 10 GB with the routing core and this routing core with the 10GB switch. 
 

note:

Your question is too long, so unfortunately we cannot answer it all with one single answer. So, here's just the first part “2.1”, please submit the next parts as separate questions so I can better explain each of them. (Please share the complete information of the question for the next parts for us to help you.)

Your question seems to be missing crucial information but we still tried to answer it as best as we could. We assumed the organization's network requirements. As we said, we’re still missing (what devices and departments need to be connected on this network), so it might be good for you to resubmit your question and we’d be happy to try again!

Which of the following cabling methods connects workstations to the closest data rooms?

Computer networks require complicated and specific cabling, particularly in business or academic settings. The cables used in cabling the networks must be made from certain materials. Backbone cabling and horizontal cabling are two main cabling methods used in today’s structured cabling system and neither is dispensable. Since backbone cabling and horizontal cabling have many differences, cables used these two structured cabling systems are also different from each other. Backbone cabling vs horizontal cabling: what’s the difference between them? What kind of cables are suitable for backbone cabling and horizontal cabling? The knowledge will be introduced in this article.

Structured Cabling System Basics

To understand backbone cabling and horizontal cabling, let’s understand the five subsystems of structured cabling firstly. These five subsystems are often found throughout a building and are connected together so that various types of data can be transmitted consistently and securely (shown in the figure below).

Which of the following cabling methods connects workstations to the closest data rooms?

Equipment Room:  A room with equipment that serves the users inside the building.

Telecommunications Room: This room contains the telecommunications equipment that connects the backbone and horizontal cabling subsystems.

Backbone Cabling: A system of cabling that connects the equipment rooms and telecommunications rooms.

Horizontal Cabling: The system of cabling that connects telecommunications rooms to individual outlets or work areas on the floor.

Work Area Components: These connect end-user equipment to outlets of the horizontal cabling system.

Backbone Cabling

The backbone cabling is also called vertical cabling or wiring. It provides interconnection between telecommunication rooms, equipment rooms and entrance facilities. These backbone cablings typically are done from floor to floor to floor. When setting up backbone cabling, several types of media can be used: unshielded twisted-pair (UTP) cable, shielded twisted-pair (STP) cable, fiber optic cable, or coaxial cable. Equipment should be connected by cables of no more than 30 meters (98 feet).

Cables for Backbone Cabling

With the emerge of Gigabit Ethernet and 10 Gigabit Ethernet, fiber optic cable is the most appropriate choice for backbone cabling since they provide much higher bandwidth than traditional Cat5, Cat6 or even Cat7 twisted pair copper cables. Another advantage of fiber is that fibers can run much longer distance than copper cable, which makes them especially attractive for backbone cabling.

Horizontal Cabling

The horizontal cabling system extends from the work area’s telecommunications information outlet to the telecommunications room (TR) or telecommunications enclosure (TE). As shown in the figure below, horizontal cabling is usually installed in a star topology that connects each work area to the telecommunications room. It includes the telecommunications outlet, an optional consolidation point, horizontal cable, mechanical terminations and patch cords (or jumpers) located in the TR or TE.

Cables for Horizontal Cabling

Both Ethernet cable and fiber optic cable can be used for horizontal cabling. Four-pair 100-ohm unshielded twisted-pair (UTP) cable (Cat5e cable, Cat 6 cable or Cat6a cable) is usually recommended for voice and fiber optic cable (two-fiber 62.5/125-micron or 50/125-micron multimode cable, or higher fiber count ) is commonly used for data transmission. To comply with EIA/TIA wiring standards, individual cables should be limited to 90 meters in length between the outlet in the work area and the patch panels in the telecommunications room. Patch cords for connecting the patch panel to hubs and switches in the telecommunications room should be no longer than 6 meters total distance. Cables connecting users’ computers to outlets should be limited to 3 meters in length.

Backbone Cabling  vs Horizontal Cabling Difference

The main difference between backbone cabling and horizontal cabling is that they cover different telecommunication service areas. Backebone cabling is to connect the entrance facilities, equipment rooms and telecommunication rooms. It also runs between floors. While horizontal cabling connects telecommunication rooms to individual outlets on the floors.

Besides, although both backbone and horizontal cabling use same types of cable, the cables used for backbone cabling have very different requirement from the horizontal cabling as backbone cabling typically passes through from floor to floor. Backbone cables must meet particular fire-rating specifications, typically OFNR (Optical Fiber Non-Conductive Riser) rated. If the backbone cable passes through plenum area (spaces in the building used for air return in air conditioning), the cable must be OFNP (Optical Fiber Non-conductive Plenum) rated. Besides, since backbone cables need to have enough strength to support its own weight, cable strength for backbone cables is also different from horizontal cables. And unlike horizontal cables, backbone cables must be secured correctly.

Conclusion

As two important parts of structured cabling, both backbone cabling and horizontal cabling play an irreplaceable role. And due to the different cabling environment, backbone cables and horizontal cables may have different specifications. FS.COM provides both Cat5, Cat6 or Cat7 UTP or STP Ethernet cable and OFNR or OFNP multimode or single mode fiber patch cables for backbone cabling and horizontal cabling.

Which cabling methods connects workstations to the closest data rooms?

Horizontal cabling extends from a Telecommunications Room or enclosure out to the individual workstation outlets or Work Area Outlet (WAO). Generally, it is installed in a star topology that links each work area to the telecommunications room.

What is the cabling from the telecom closet to the main cross connect or computer center called?

....but most people call it "premises cabling" for its application or "structured cabling" after the "568" standard. Premises cabling is the infrastructure for telephone and LAN connections in most commercial installations and even in some modern homes.

What is the cable from the telecom room to the work area outlet is called?

3. Backbone cabling. The backbone cabling is also called vertical cabling or wring. It offers the interconnection between entrance facilities, telecommunication rooms, and equipment rooms. This type of cabling is done between buildings or from floor to floor.

Which standard is also known as structured cabling?

The American National Standards Institute and Telecommunications Industry Association set forth a series of standards, ANSI/TIA-568, to introduce guidelines for all aspects of residential and commercial building cable distribution systems. These standards shape the structured cabling system.
