RCDD-001 Cable Practice Questions

You must place CAT6 cable above a factory floor with automated welding machines and hammer forges. Of the following, what type of shielding would be most effective?

• AA. Multi-layer braid
• BB. Foil and braid
• CC. Solid metallic conduit
• DD. Flex metallic conduit
• EE. Sc
• FF. 40 PVC conduit

Which characteristic is an advantage of copper based media over optical fiber cable?

• AA. Weight
• BB. Corrosion resistance
• CC. Ability to handle analog signals
• DD. Susceptibility to EMI
• EE. Very high data rates

A video camera has a coaxial cable output. The video signal is to be distributed to devices that have balanced twisted pair inputs. The transition between these two different transmission media can be accomplished by using a:

• AA. Balun
• BB. Converter
• CC. Modulator
• DD. Cross connect
• EE. Transceiver

You are placing Category 6 unshielded twisted-pair (UTP) in cable tray down a hallway past the elevator mechanical room. What action should you take to avoid effects of electromagnetic interference (EMI)?

• AA. Provide a minimum separation of 1194 mm (47 in)
• BB. Provide a minimum separation of 2060 mm (81 in)
• CC. Require the architect to install metallic foil shielding on the mechanical room walls
• DD. Provide RMC/IMC (rigid metallic conduit/intermediate metal conduit) through all areas within 4.6 m (15 ft) of the mechanical room
