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?
Correct answer: C - Category 6A
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?
Correct answer: B - 40%
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:
Correct answer: A - 110 N (25 lbf)
An installer is terminating an 8-position (8P8C) modular plug using the T568B wiring scheme. Which colors terminate on pins 1 and 2, respectively?
Correct answer: B - White/Orange and Orange
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:
Correct answer: D - Lower insertion loss and lower reflectance
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?
Correct answer: C - The equipment cords
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:
Correct answer: C - A split pair
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:
Correct answer: D - Removed from accessible areas
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:
Correct answer: A - Heat buildup within the cable bundle
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?
Correct answer: B - The local building code
