Why are most of the access points built with two antennas?
  1. To send data and the other to receive data
  2. As a standby for reliability
  3. To overcome multipath
  4. To transmit on two different channels
Explanation
Answer - C - Access points are built with two antennas to overcome multipath.

Key Takeaway: Access points use two antennas to implement antenna diversity and overcome multipath. Multipath is caused by reflected RF waves and can disrupt or corrupt data transmissions. Access points sample inputs from both antennas and use the best signal. Access points normally transmit on the antenna last used for receiving.
