Demo Questions
Question 1
A reasonable approximation for the signal speed in 100 ohm balanced twisted pair cable is __________, where c is the velocity of light in free space.
- 0.2 c
- 0.4 c
- 0.6 c
- 08 c
- 0.9 c
Correct answer: C
Question 2
Assume that the optical power transmitted by a 62.5/125 multimode fiber is distributed uniformly across its core. If this fiber is perfectly coupled (i.e., the two fibers are aligned and abutted) to a 50/125 fiber, what is the percent of power that is lost?
- 0 percent
- 36 percent
- 50 percent
- 80 percent
- 100 percent
Correct answer: B
Question 3
You must place a cable between 2 equipment locations with separate grounds having a potential difference between them of 2.1 V rms.
Which one of the following cables should NOT be used?
- Multimode
- Singlemode
- UTP
- STP
Correct answer: D
Question 4
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:
- Balun
- Converter
- Modulator
- Cross connect
- Transceiver
Correct answer: A
Question 5
Optical transmitters are typically one of the following types EXCEPT:
- Light-emitting diode (LED)
- Short wavelength laser compact disc (CD)
- Vertical cavity surface emitting laser (VCEL)
- Laser diode (LD)
- Overfilled launch (OFL)
Correct answer: E
Question 6
During a site survey you notice that several CRT displays in the vicinity of the engineering copy center have sporadic visual distortion. What is the MOST likely cause?
- Electromagnetic interference (EMI)
- Radio frequency interference (RFI)
- (EMC)
- Fast transients
- Electromagnetic discharge (ESD)
Correct answer: A
Question 7
The potential for ______ occurs when devices or systems share a common electromagnetic environment and their operational frequencies overlap.
- Electromagnetic interference (EMI)
- (EMC)
- Radio frequency interference (RFI)
- Fast transients
- Electrostatic discharge (ESD)
Correct answer: A
Question 8
Which of the following is an undesirable electromagnetic effect on a device(s)?
- (EMC)
- Electromagnetic interference (EMI)
- Radio frequency interference (RFI)
- Fast transients
- Electrostatic discharge (ESD)
Correct answer: B
Question 9
You are required by architectural design to place UTP cables in the same space as unshielded power lines. How should you proceed with the placement of your cables?
- Require the architect/electrical engineer to place shielding in the space before your UTP is placed.
- You should provide a minimum separation of 610 mm (24 in).
- You should provide a minimum separation of 229 mm (9 in).
- You should provide a minimum of two 101 mm (4 in) RMC.
Correct answer: B
Question 10
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)?
- Provide a minimum separation of 1194 mm (47 in)
- Provide a minimum separation of 2060 mm (81 in)
- Require the architect to install metallic foil shielding on the mechanical room walls
- Provide RMC/IMC (rigid metallic conduit/intermediate metal conduit) through all areas within 4.6 m (15 ft) of the mechanical room
Correct answer: A
