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?
- Category 5e
- Category 6
- Category 6A
- 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?
- 31%
- 40%
- 53%
- 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:
- 110 N (25 lbf)
- 45 N (10 lbf)
- 220 N (50 lbf)
- 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?
- White/Green and Green
- White/Orange and Orange
- White/Blue and Blue
- 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:
- Higher loss but quicker and simpler to install in the field
- Equivalent loss using index-matching gel
- Lower cost with no specialized equipment
- 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?
- The fixed horizontal cable
- The telecommunications outlet
- The equipment cords
- 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:
- A short between two conductors
- An open conductor on one pair
- A split pair
- 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:
- Labeled and left in place
- Capped and left in the pathway
- Coiled and secured above the ceiling
- 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:
- Heat buildup within the cable bundle
- Increased alien crosstalk between cables
- Greater signal attenuation from EMI
- 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?
- The ANSI/TIA standard, as the industry best practice
- The local building code
- Whichever was published more recently
- The manufacturer's installation instructions
Show answer & explanation
Correct answer: B - The local building code
