Which two types of signal interference are reduced more by STP than by UTP? (Choose two.)

Which two types of signal interference are reduced more by STP than by UTP? (Choose two.)

• RFI
• white noise
• MDF
• dispersion
• EMI
  

  Explanation: RFI, EMI, and crosstalk cause interference to the electrical signals that are transmitted through copper cables. Both UTP and STP use twisted pairs of wires that help protect against crosstalk. However, STP provides greater protection against RFI and EMI than UTP provides.
