BICSI Installer 2 Copper Certification Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

(Covers Installation Requirements, Copper Media, Testing, Standards, Safety, and Troubleshooting)

• What is the primary function of a horizontal cross-connect (HC)?
• To connect backbone cables to work area outlets
• To connect horizontal cabling to backbone cabling
• To terminate patch cords in the equipment room
• To manage optical fiber connections

Rationale: The horizontal cross-connect links horizontal cabling to the

backbone cabling, forming part of the structured cabling system per ANSI/TIA-568 standards._

• / 4

2. The maximum allowable length for a horizontal copper cable is:

• 90 meters including patch cords
• 95 meters total length
• 90 meters for permanent link, plus 10 meters for patch cords
• 100 meters for cable only

Rationale: TIA-568 specifies a 100-meter channel—90 meters for

permanent link and 10 meters for patch cords._

• What tool is used to ensure pairs are not split during termination?
• Tone generator
• Wire map tester

C. OTDR

• Cable stripper

Rationale: Wire map testers verify correct pair terminations, ensuring no

splits or miswires._

• Which copper category supports 10GBASE-T up to 100 meters?
• Category 5e
• Category 6
• Category 6A
• Category 7

Rationale: Category 6A (Augmented Cat 6) supports 10GBASE-T Ethernet

up to 100 meters._ 2 / 4

• What is the purpose of color coding in 110 blocks?
• For decorative purposes
• To identify pairs and ensure correct wiring sequences
• To improve signal transmission
• To reduce crosstalk

Rationale: Color codes ensure correct T568A or T568B pair terminations._

6. The T568A and T568B standards differ in:

• Cable length
• Pair-to-pin assignments
• Impedance
• Wire gauge

Rationale: The only difference between T568A and T568B is the pair-to-pin

configuration on the connector._

• What is NEXT in copper testing?
• Noise from external sources
• Crosstalk measured at the same end as the signal source
• Return loss
• Attenuation between ends 3 / 4

Rationale: Near-End Crosstalk (NEXT) measures interference at the

transmitting end._

• What should be done before pulling copper cables into a conduit?
• Apply grease to the cable
• Inspect conduit for damage and obstructions
• Preload conduit with other cables
• Twist cables tightly together

Rationale: Inspecting the conduit ensures no damage that could harm the

cable during pulling._

• Which type of cable is most common for LAN horizontal cabling?
• Coaxial

B. UTP

C. STP

• Twinax

Rationale: Unshielded Twisted Pair (UTP) is the most widely used copper

cable for LAN horizontal cabling._

• What is the maximum untwist length allowed for a twisted pair at a

termination?

• 1 inch
• / 4
