When terminating a Cat 6 cable to a 110-style punch-down block, which tool setting should be used?
Answer: Cut-and-seat
The cut-and-seat setting simultaneously seats the conductor and trims the excess wire in one motion.
What is the maximum allowed untwisting of pairs when terminating Cat 6A to a keystone jack?
Answer: 13 mm (0.5 in)
TIA-568 limits pair untwisting to 13 mm (0.5 inch) for Cat 6A to maintain crosstalk performance.
A technician notices intermittent failures on a newly terminated Cat 5e link. The MOST likely cause is:
Answer: Split pairs at the termination
Split pairs cause near-end crosstalk (NEXT) failures that appear intermittent under load.
Which wiring standard places orange-white on pin 1 and orange on pin 2?
Answer: T568B
T568B assigns orange-white to pin 1 and orange to pin 2, making it the most common commercial standard.
When using a modular crimping tool on an RJ-45 connector, what defect results from insufficient crimp force?
Answer: High contact resistance at the pins
Insufficient crimp force leaves the gold contacts partially seated, creating high resistance and intermittent connectivity.
A cable tester reports a 'reversed pair' on a Cat 5e patch cord. Which pins are swapped?
Answer: Both conductors within the same pair
A reversed pair means the tip and ring of a single pair are transposed (e.g., pin 3 and pin 6 swapped on pair 2).
What is the purpose of the strain relief boot on an RJ-45 patch cord?
Answer: Prevent the cable from bending sharply at the connector entry
The strain relief boot maintains the minimum bend radius at the plug entry point, preventing conductor stress failures.
