1. A type of interference that occurs when cables are bundled together for long lengths is known as:

  • crosstalk
  • cross-interference
  • bundled-interference
  • crosscheck

Explanation: Crosstalk occurs when cables are bundled together for long lengths.

  • UTP
  • STP
  • fiber-optic
  • coaxial

Explanation: Shielded twisted-pair (STP) is used in electrical environments in which EMI and RFI are so strong that shielding is a requirement to make communication possible.

3. Which of the following is the most common type of connector used to terminate twisted-pair cabling?
