ACTUAL Questions and CORRECT
Answers
Cross Connects, Backbone Cabling, and Administration - CORRECT ANSWER -
Administration systems include requirements for; identifiers - that serve to locate the element
record and administration scheme such as the standards found in ANSI/TIA 606-B, records -
which can be paper based, spreadsheets, database programs, or computer programs specially
designed for that purpose, and labeling - with a variety of methods to display identifiers for the
buildings, pathways, spaces, cabinets, racks, cabling, connectors, the choice of material,
fastening method, environmental, performance, and security issues. Common methods for
displaying identifiers include bar codes, graphics, labels, tags, and electronic identifiers
There are four classes of administration:
Class 1 - 1 ER which is the only telecommunications space on the site
Class 2 - 2 or more telecommunications spaces in a building
Class 3 - Multiple buildings at a single site
Class 4 - Multiple sites or campuses
Data Centers - are buildings or portions of a building whose primary function is to house a
computer room, including the data center electrical rooms, mechanical rooms, storage rooms,
staging rooms, operations and command center, and other spaces whose primary functions are to
support the computer room.
For redundancy, in accordance with ANSI/BICSI-002 stamdards, classes of Data Centers have
been established.
Class 0 - a single path data center that meets the minimum requirements but cannot be classified
as Class 1 or higher
Class 1 - the single path data center
Class 2 - the single path data center with redundant components
Class 3 - the concurrently maintainable and operable data center
,Class 4 - the fault tolerant data center that contains two separate infrastructures with their own
set of redundant components.
Some of the key areas include a Telecommunications Entrance Room that contains the External
Network Interface (ENI), wh
American Wire Gauge (AWG) - CORRECT ANSWER -Roughly represents the number of
steps that were involved in the process of wire drawing.
Smaller Numbers: Larger wires (fewer drawing steps are involved)
Larger Numbers: Smaller wires (more drawing steps are involved)
A gauge change of 3 numbers: Doubles or halves the conductors resistance and cross sectional
area
A gauge change of 6 numbers: Doubles or halves the conductors diameter
Resistance, Inductance, Capacitance and Impedance - CORRECT ANSWER -Resistance:
the property of a conductor to resist the flow of electricity through it. Expressed in Ohms - One
ohm of resistance will allow 1A of current to flow when 1 V of electrical pressure is applied
where V is voltage in volts, I is current in amperes, and R is resistance in ohms. Resistance
changes in proportion to length. High temperatures increase the conductors resistance by
approximately 2% for each 10 degrees Fahrenheit (5.5 C).
Inductance: a property of an electromagnetic field built around a conductor that opposes any
changes in current flow in a circuit, both ac and varying dc. The basic unit of inductance is a
Henry (H). Inductive coupling is the transfer of energy from one circuit to another through this
field. Inductive reactance is a force that opposes change in the direction of current flow on a
conductive path. Is measured in ohms. Directly proportional to the frequency.
Capacitance: a property of conductors that allows storage of electric charges when potential
differences (voltages) exist between conductors. Cause a voltage difference between two wires
when separated by insulation, resulting in a buildup (or storage of electric charges) of
capacitance between the wires. Is measured in farads (F). Normally measured in microfarads
, (one millionth of a farad), nanofarads (one billionth of a farad), or picofarads (one trillionth of a
farad).
Impedance (Z): in AC circuits, the total opposition to current flow. Measured in ohms - the
combined effects of resistance, inductive reactance, and capacitive reactance of the circuit.
Characteristic Impedance: the input impedance of a uniform analog transmission line of infinite
length. Impedance mismatches can cause: Attenuation, distortion, or corruption of transmitted
and received signals. Most balanced twisted-pair cabling used for ICT exhibits a charact
1st step in setting up cable - CORRECT ANSWER -is to secure the area
1st step when pulling horizontal cable - CORRECT ANSWER -in conduit is to choose a
method of establishing cable run distance.

Maximum Cable Run Distance - CORRECT ANSWER -90 M (295 Ft)
Maximum single conduit segment - CORRECT ANSWER -no more than 30 M (100 ft)
number of 90 degree bends per 100 ft in and bend radius of conduit - CORRECT
ANSWER -no more than 2 90's
2 inches or less 6 times internal diameter
2 inches or more 10 times the internal diameter
Cable Bend Radii - CORRECT ANSWER -1 Patch cord 1
