2024 BICSI ITSMM EXAM WITH
CORRECT ANSWERS
What is inductace? - CORRECT-ANSWERS1) The property of an electrical
force field built around a conductor when current flows through it. 2) The
resistance to change in current.
What is impedance? - CORRECT-ANSWERSThe total opposition (resistance
and reactance [capacitance and inductance]) that a circuit, cable or
component offers to the flow of alternating current (ac) at a given frequency.
It is measured in ohms.
What is a link? - CORRECT-ANSWERSRack to jack
What is hearing range for humans? - CORRECT-ANSWERS20 Hz- 20,000 Hz
What is bandwidth? - CORRECT-ANSWERSA range of frequencies available for
signaling expressed in Hertz (Hz). It is used to denote the potential
information handling capacity of the medium, device or system.
What is attenuation? - CORRECT-ANSWERSThe decrease in magnitude or the
power loss of a signal that propagates between points, expressed in decibels
(dB) as the ratio of a received signal to transmitted signal level.
What is insertion loss? - CORRECT-ANSWERSThe signal loss resulting from
the insertion of a component, or link, or channel, between a transmitter and
receiver (often referred to as attenuation)
What is reflection? - CORRECT-ANSWERSThe abrupt change in direction of a
wave front (wireless signal, light signal) at the interface between two
dissimilar media such that the incident wave front returns into the medium
from which it originated. In wireless transmission, radio frequency (RF)
waves can be strongly reflected off the surface of a lake, the side of a large
building, or off walls inside a building. (In optical fiber transmission see
Fresnel reflection.)
What is refraction? - CORRECT-ANSWERSThe change of direction
experienced by a wave of radiated energy when passing from one medium
to another having a different dielectric constant or index of refraction
What is a channel? - CORRECT-ANSWERSRack to jack PLUS patch cords
, What is a mandrel? (when using with optical fiber) - CORRECT-ANSWERSA
cylindrical object around which a multimode optical fiber cable is wrapped to
cancel high order modes during testing.
What is modal dispersion? - CORRECT-ANSWERSA characteristic of
transmission in an optical fiber that results from different lengths of the light
paths taken by the many modes of light as they travel down the fiber from
source to receiver. Also called modal distortion.
What is chromatic dispersion? - CORRECT-ANSWERSA result of the
phenomenon that the velocity of propagation in a medium is frequency
dependent, which causes the frequency components of a pulse to lose phase
coherence as it propagates (transmitted pulse will spread out as it
propagates)
What is a code? - CORRECT-ANSWERS"A rule or set of rules intended to
ensure safety during the installation and use of materials, components,
fixtures, systems, premises, and related subjects." Codes typically are
invoked and enforced through government regulation.
A code ensures the:
-Practical safeguarding of persons and property from hazards.
-Quality of construction
What is a standard? - CORRECT-ANSWERSIs an accepted collection of
requirements and recommendations for the defining, construction,
evaluation, application or comparison of materials, equipment, products and
services.
Also to ensure a minimum level of acceptable performance.
What is a regulation? - CORRECT-ANSWERSis an authoritative rule that
controls or governs behavior leading to uniformity.
What is SCS? - CORRECT-ANSWERSStructured Cabling System
What is MC (CD)? - CORRECT-ANSWERSBuilding or campus serving cross
connect in the ER for connecting entrance cabling, backbone cabling, and
equipment cabling.
Main cross connect/ campus distributor
What is IC (BD)? - CORRECT-ANSWERSBuilding-serving cross-connect points
located between the MC (CD) and HC (FD) in interbuilding backbone cabling.
