Which of the following is not a hardware or software option on a wireless bridge?
  1. Fixed antennas
  2. Full-duplex radio links
  3. Advanced filtering capabilities
  4. Removable radio cards
Explanation
Answer - B - Full-duplex radio links are not a hardware or software option on a wireless bridge.

Key Takeaway: Radios can either transmit or receive on a particular frequency, but not both simultaneously; hence, all wireless LAN radios are half duplex. Full-duplex communication is not an option available on a wireless LAN. Wireless LAN radio manufacturers do not build their radios in a full duplex mode because of the very high cost associated with it.
