BICSI ITSMM Exam Questions And Accurate
Answers 2024-
What is inductance? -1) The property of an electrical force field built around a conductorwhen current flows through it. 2) The opposition to the change in current.
What is impedance? - Answer The total opposition, resistance and reactance[capacitance and inductance], which a circuit, cable or component offers to the flow of alternating current, at a given frequency. It is measured in ohms. What is hearing range for humans? - Answer 20 Hz- 20,000 Hz What is modal dispersion? - Answer A characteristic of transmission in an optical fiberthat 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? Answer A result of the phenomenon that the velocity ofpropagation in a medium is dependent on frequency-the frequency components of a pulse will lose phase coherence as it propagates (the transmitted pulse will spread out itas it propagates).
What is a code? - "A rule or set of rules intended to ensure safety during the installationand 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? - Answer Is an accepted collection of requirements andrecommendations 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? - Answer is an authoritative rule that controls or governsbehaviour leading to uniformity. What is SCS? - Answer Structured Cabling System What is MC (CD)? -Building or campus serving cross connect in the ER for connectingentrance cabling, backbone cabling, and equipment cabling. Main cross connect/ campus distributorWhat is IC (BD)? -Building-serving cross-connect points located between the MC (CD) and HC (FD) in interbuilding backbone cabling. Intermediate cross connect/ building distributor What is HC(FD)? -Answer Floor-serving location for the cross connection of horizontalcabling to other cabling and equipment. Horizontal cross connect/ floor distributor A first level backbone consists of: -Answer cabling that is installed between an MC(CD)and an IC(BD) or a horizontal cross-connect (HC [floor distributor (FD)].
A second level backbone consists of: - Answer is a cable that is installed between an IC(BD) and an HC (FD).
The color.Orange - Answer Demarcation Point The color.Green - Answer Network Connections (network, auxiliary equipment) The color.Purple - Answer Common equipment (connections to PBX, mainframecomputer, LAN, multiplexer)

Tip colors - Answer White Red BlackYellow Violet Ring - Answer Blue
Orange Green BrownSlate
What are binder groups (binders)? - Answer For cables with more than 25 pairs isformed into a bundle and has a colored binder (tape or thread) placed around the bundle. The colored binder wraps follow the same color code as the individual pair colorcode.
white/blue binder group 1-25red/blue binder/group 126-
This is for cables up to 600 pairs violet/slate pair group isn't used What is a super group binder? - Answer When cables exceed 600 pairs 24 binders arewrapped in a colored super group binder the color used is tip only white 1- red 601-1200black 1201- yellow 1801- Data Center - What is it? Answer: A building or part of a building whose primary functionis to house a computer room and its associated support spaces.
Includes Data Center Electrical Rooms, Mechanical Rooms, Storage Rooms, StagingRooms, Operations and Command Center
Redundancy Class 0 - A single path data center that meets minimum requirements ofANSI/BICSI, but cannot be classified as Class 1 or higher
RBB - Answer rack bonding busbar SBB - Answer secondary bonding busbar TBB- 6 AWG- interconnects the PBB to the SBB - Answer telecommunications bondingbackbone
TBC connects the electrical systems grounding electrode system to the PBB - Answertelecommunications bonding conductor
GEC - Answer grounding electrode conductor ACEG - Answer alternating current equipment ground TEBC connects equipment cabinets and racks to the closets PBB or SBB - AnswerTelecommunications Equipment Bonding Conductor
RBC - Answer Rack bonding conductor Bandwidth - Answer A 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. Attenuation - Answer The decrease in magnitude or the power loss of a signal thatpropagates between points, expressed in decibels (dB) as the ratio of a received signal to transmitted signal level. What is insertion loss? - Answer The signal loss resulting from the insertion of acomponent, or link, or channel, between a transmitter and receiver (often referred to as attenuation)
What is reflection? - Ans The abrupt, sharp bending of a wave front (wireless signal,light signal) at the surface between two unlike media so that the incident wave front bounces back into the medium from which it came. In wireless transmission, RF wavescan be strongly reflected by the surface of a lake, the side of a large building, or off walls inside a building. (In optical fiber transmission see Fresnel reflection.) Refraction - Answer The bending of a wave of radiated energy that occurs when theenergy passes from one medium into another that has a different dielectric constant or index of refraction Link - Answer Rack to jack Channel - Answer Rack to jack PLUS patch cords What is a mandrel? (when using with optical fiber) - Answer A cylindrical object aroundwhich a multimode optical fiber cable is wrapped to cancel high order modes during testing.
