• What does BICSI stand for?
• Building Industry Consulting Service International
• Building Infrastructure Cabling Standards Institute
• Building Industry Consulting Service International, Inc.
• 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:

• Design telecommunications systems
• Install and terminate low-voltage cabling systems 1 / 4

• Inspect telecommunications facilities
• Certify network systems

Rationale: Installer 1 professionals focus on installation, termination,

and basic testing of copper and optical fiber cabling systems.

• What is the maximum horizontal cabling length allowed by TIA/EIA

standards?

• 150 meters
• 90 meters
• 100 meters
• 120 meters

Rationale: The maximum horizontal cabling length is 90 meters for

permanent link, plus up to 10 meters for patch cords.

• Which of the following cables is typically used for horizontal cabling?

A. RG-6

• Coaxial cable
• Category 6 UTP cable
• 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:

• Protect cable from electromagnetic interference
• Connect two buildings together
• Terminate horizontal cables and provide patching connections 2 / 4

• Amplify network signals

Rationale: Patch panels serve as termination points for horizontal

cables, allowing flexible connections to network equipment.

• Which color code standard is more common in the U.S. for T568A and

T568B wiring?

A. T568A

B. T568B

• Both equally
• None

Rationale: Although both are recognized, T568B is more commonly

used in the U.S. for consistency with older systems.

• What tool is used to terminate cables on a 110-type block?
• Crimping tool
• Cable stripper
• Punch-down tool
• 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:

• PVC-jacketed cable
• Non-plenum cable
• Plenum-rated cable (CMP)
• Riser-rated cable 3 / 4

Rationale: Plenum-rated cables have low-smoke and low-toxicity

jackets suitable for use in air-handling spaces.

• Which of the following is a safety precaution before starting a ladder

installation?

• Make sure it’s near power lines
• Test for static
• Inspect the ladder for defects
• 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:

• Excessive cable length
• Untwisting too much of the pair during termination
• Using shielded cable
• 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:

• Open air plenums
• Vertical runs between floors
• Underground conduits
• Outdoor aerial installations
