When designing a connection to an outlying building you decide to choose a physical ring.
Your primary reason for considering a physical ring is:
- A . You have easy access to an existing pathway
- B . The design is quick and easy to install
- C . The campus suits this design
- D . The design is cost effective
- E . The physical ring provides a redundant cable path for disaster recovery
You are given a choice of methods of routing backbone cabling vertically through a building.
The one option that you do NOT want to use is:
- A . Open shafts
- B . Metallic raceways
- C . Slots
- D . Sleeves
- E . Elevator shafts
When designing a campus distribution system involving small buildings with only one horizontal cross-connect (HC) [Floor distributor (FD)] per building, you can eliminate the need for a(n):
- A . Intermediate cross-connect (IC) Building distributor (BD)
- B . Main cross-connect (MC) Campus distributor (CD)
- C . Horizontal cross-connect (HC) Floor distributor (FD)
- D . Entrance facility (EF)
- E . Latching connector (LC)
The RECOMMENDED balanced twisted-pair cable for building backbone cabling consists of ________ round solid copper conductors with a nominal characteristic of 100 ohm.
- A . 20-24 AWG
- B . 22-26 AWG
- C . 23-24 AWG
- D . 24-22 AWG
- E . 26-20 AWG
In reviewing your client’s network needs for today and 5 years into the future, you note their current specs call for a 1Gb/s network within a campus environment, with little or no possibility of any increased bandwidth demands until they move to their planned future site. The building is not large, and the cable lengths will not exceed 550 m (1804 ft).
Your recommendation for the fiber to be installed in the backbone is:
- A . OM1 fiber
- B . OM2 fiber
- C . OM3 fiber
- D . OM1, OM2, or OM3 will work
- E . OS1 equipped with attenuators
Multimode optical fiber is generally used for campus or building applications due to the ability to use cost effective:
- A . Connectors
- B . Cable
- C . Installation methods
- D . Transceivers
- E . Designs
One advantage of using preconnectorized jumpers and cables is:
- A . They are less costly than field connectorized connectors
- B . The cables are more rugged and can handle higher pull tensions
- C . They come with factory certified quality of terminations
- D . They require additional engineering time thereby providing a higher degree of reliability
- E . The technician does not need to be concerned with the water blocking components of the cable
You have been asked to design a backbone cable connecting two large campus buildings. Your pathways will include using conduits, maintenance holes, and one section of 100 m (328 ft) of direct buried optical fiber cable.
Your choice of fiber optic cable type recommendation is a:
- A . Distribution cable
- B . Loose tube cable
- C . Loose tube cable containing a water blocking compound
- D . Distribution cable with an armored coating
- E . Distribution cable with a water blocking compound
You have been asked to project manage a fiber cable backbone installation. In the course of the installation, you notice the fiber cable with a 25 mm (1 in) outside diameter is being installed into a small TR, and the cable is being installed into a tight corner.
Based on your knowledge of minimum bend radius requirements for fiber cable, you must ensure that the MINIMUM cable bend radius of _______________ is provided when the cable installation is completed.
- A . 254 mm (10 in)
- B . 305 mm (12 in)
- C . 381 mm (15 in)
- D . 457 mm (18 in)
- E . 610 mm (24 in)
The decision regarding the number of optical fibers to install (fiber strand count) in a backbone depends largely on all of the following EXCEPT:
- A . Level of multiplexing
- B . Intended end-user applications
- C . Physical topology of the cabling system
- D . Distance between telecommunications room (TR)
- E . Cabling system configuration
