Which of the following is NOT true about Unshielded Twisted Pair (UTP) cables?

  1. A.They have a higher resistance to EMI than STP cables.
  2. B.They are commonly used in local area networks (LANs).
  3. C.They are lighter and more flexible than STP cables.
  4. D.They are cost-effective for short-distance communication.
Show answer
Correct answer: A. They have a higher resistance to EMI than STP cables.
