N10-005 Question #584: Real Exam Question with Answer & Explanation
The correct answer is D: CAT6. Higher-category twisted-pair cables use more twists per inch to reduce crosstalk and electromagnetic interference, with CAT6 having the highest twist rate among the listed options.
Question
Which of the following cables has the MOST twists per inch?
Options
- ACAT3
- BCAT5
- CCAT5e
- DCAT6
Explanation
Higher-category twisted-pair cables use more twists per inch to reduce crosstalk and electromagnetic interference, with CAT6 having the highest twist rate among the listed options.
Common mistakes.
- A. CAT3 has the fewest twists per inch of the listed options, supporting only up to 10 MHz and designed for voice-grade applications.
- B. CAT5 has more twists than CAT3 but fewer than CAT5e and CAT6, supporting up to 100 MHz.
- C. CAT5e has more twists than CAT5 with improved crosstalk specifications, but fewer twists per inch than CAT6.
