1. What does BICSI stand for?
A. Building Industry Consulting Service International
B. Building Infrastructure Cabling Standards Institute
C. Building Industry Consulting Service International, Inc.
D. Broadband Infrastructure and Communication Systems
International
Rationale: BICSI stands for Building Industry Consulting Service
International, Inc., which develops standards and provides training and
certifications in the information and communications technology (ICT)
industry.
2. The primary role of a BICSI Installer 1 is to:
A. Design telecommunications systems
B. Install and terminate low-voltage cabling systems
, C. Inspect telecommunications facilities
D. Certify network systems
Rationale: Installer 1 professionals focus on installation, termination,
and basic testing of copper and optical fiber cabling systems.
3. What is the maximum horizontal cabling length allowed by TIA/EIA
standards?
A. 150 meters
B. 90 meters
C. 100 meters
D. 120 meters
Rationale: The maximum horizontal cabling length is 90 meters for
permanent link, plus up to 10 meters for patch cords.
4. Which of the following cables is typically used for horizontal cabling?
A. RG-6
B. Coaxial cable
C. Category 6 UTP cable
D. Shielded twisted pair Category 3
Rationale: Category 6 UTP cable is the standard choice for horizontal
cabling due to its high bandwidth and reduced crosstalk.
5. The function of the patch panel is to:
A. Protect cable from electromagnetic interference
B. Connect two buildings together
C. Terminate horizontal cables and provide patching connections
, D. Amplify network signals
Rationale: Patch panels serve as termination points for horizontal
cables, allowing flexible connections to network equipment.
6. Which color code standard is more common in the U.S. for T568A and
T568B wiring?
A. T568A
B. T568B
C. Both equally
D. None
Rationale: Although both are recognized, T568B is more commonly
used in the U.S. for consistency with older systems.
7. What tool is used to terminate cables on a 110-type block?
A. Crimping tool
B. Cable stripper
C. Punch-down tool
D. Wire cutter
Rationale: A punch-down tool is used to seat and cut wires onto
insulation displacement contacts (IDC) on a 110-type block.
8. When installing cable in a plenum space, you must use:
A. PVC-jacketed cable
B. Non-plenum cable
C. Plenum-rated cable (CMP)
D. Riser-rated cable
, Rationale: Plenum-rated cables have low-smoke and low-toxicity
jackets suitable for use in air-handling spaces.
9. Which of the following is a safety precaution before starting a ladder
installation?
A. Make sure it’s near power lines
B. Test for static
C. Inspect the ladder for defects
D. Tie it with a cable
Rationale: Inspecting the ladder ensures it is stable and safe for use,
preventing falls or injuries.
10. The most common cause of crosstalk in twisted-pair cables is:
A. Excessive cable length
B. Untwisting too much of the pair during termination
C. Using shielded cable
D. Grounding issues
Rationale: Untwisting more than ½ inch of cable pairs can increase
near-end crosstalk, degrading performance.
11. A riser-rated cable (CMR) is used for:
A. Open air plenums
B. Vertical runs between floors
C. Underground conduits
D. Outdoor aerial installations
