These 10 free BICSI questions are organized by exam domain, so you can see how each part of the BICSI blueprint is tested. Reveal the answer and explanation under each question.

Domain 1: Safety Practices 15% of exam

Question 1

A project specification requires a horizontal copper cabling system capable of supporting 10GBASE-T over the full 100-meter (328-foot) channel. What is the LOWEST cabling category that meets this requirement?

  1. Category 5e
  2. Category 6
  3. Category 6A
  4. Category 8
Show answer & explanation

Correct answer: C - Category 6A

Domain 2: Structured Cabling Fundamentals 20% of exam

Question 2

An installer is sizing a conduit that will contain four communications cables. According to the National Electrical Code, what is the maximum allowable conduit fill?

  1. 31%
  2. 40%
  3. 53%
  4. 60%
Show answer & explanation

Correct answer: B - 40%

Domain 3: Copper Cable Installation 20% of exam

Question 3

Before pulling a single 4-pair UTP cable, an installer checks the maximum pulling tension so the cable is not stretched in a way that degrades transmission performance. That maximum tension is:

  1. 110 N (25 lbf)
  2. 45 N (10 lbf)
  3. 220 N (50 lbf)
  4. 445 N (100 lbf)
Show answer & explanation

Correct answer: A - 110 N (25 lbf)

Domain 4: Termination and Connectorization 20% of exam

Question 4

An installer is terminating an 8-position (8P8C) modular plug using the T568B wiring scheme. Which colors terminate on pins 1 and 2, respectively?

  1. White/Green and Green
  2. White/Orange and Orange
  3. White/Blue and Blue
  4. White/Brown and Brown
Show answer & explanation

Correct answer: B - White/Orange and Orange

Domain 5: Testing and Troubleshooting 15% of exam

Question 5

A technician must splice a single-mode fiber backbone where minimizing insertion loss and back reflection is the top priority. Compared with a mechanical splice, a fusion splice generally provides:

  1. Higher loss but quicker and simpler to install in the field
  2. Equivalent loss using index-matching gel
  3. Lower cost with no specialized equipment
  4. Lower insertion loss and lower reflectance
Show answer & explanation

Correct answer: D - Lower insertion loss and lower reflectance

Domain 6: Documentation and Standards Compliance 10% of exam

Question 6

A field tester is configured to certify the permanent link of a horizontal copper run. Which component is NOT included in the permanent link measurement?

  1. The fixed horizontal cable
  2. The telecommunications outlet
  3. The equipment cords
  4. The patch-panel connection
Show answer & explanation

Correct answer: C - The equipment cords

Question 7

A newly installed Category 6 link passes the wire map test, but the certification tester reports a NEXT (near-end crosstalk) failure. The MOST likely cause is:

  1. A short between two conductors
  2. An open conductor on one pair
  3. A split pair
  4. A reversed pair
Show answer & explanation

Correct answer: C - A split pair

Question 8

During a retrofit, an installer finds communications cable above an accessible ceiling that is not connected to any equipment and is not tagged for future use. According to the NEC, this cable must be:

  1. Labeled and left in place
  2. Capped and left in the pathway
  3. Coiled and secured above the ceiling
  4. Removed from accessible areas
Show answer & explanation

Correct answer: D - Removed from accessible areas

Question 9

As the number of cables carrying Power over Ethernet (PoE) within a single bundle increases, an installer must manage one effect in particular. The primary concern that may require reducing the bundle size or derating is:

  1. Heat buildup within the cable bundle
  2. Increased alien crosstalk between cables
  3. Greater signal attenuation from EMI
  4. Reduced bend radius at the bundle center
Show answer & explanation

Correct answer: A - Heat buildup within the cable bundle

Question 10

On a job site, a requirement in the local building code directly conflicts with a recommendation in an ANSI/TIA standard. Which should the installer follow?

  1. The ANSI/TIA standard, as the industry best practice
  2. The local building code
  3. Whichever was published more recently
  4. The manufacturer's installation instructions
Show answer & explanation

Correct answer: B - The local building code
