220-801 Question #776: Real Exam Question with Answer & Explanation
The correct answer is A: UTP straight-through. A UTP straight-through cable uses the same wiring standard (T568A or T568B) on both ends, so the color-coded pairs match identically at each connector.
Question
Which of the following has color codes that match on both ends (e.g. orange-white, orange, green- white, blue, blue-white, green, brown-white, brown)?
Options
- AUTP straight-through
- BUTP crossover
- CMulti-mode fiber
- DSingle-mode fiber
Explanation
A UTP straight-through cable uses the same wiring standard (T568A or T568B) on both ends, so the color-coded pairs match identically at each connector.
Common mistakes.
- B. A UTP crossover cable intentionally swaps transmit and receive pairs between ends, so the color codes do not match on both sides.
- C. Multi-mode fiber uses optical strands and has no copper color codes; connectors are identified by type (e.g., LC, SC), not wire colors.
- D. Single-mode fiber also uses optical strands and does not have copper wire color coding.
