Two co-located 802.11b/g/n APs can interfere with one another and cause contention and collisions, even when the two APs are operating on non-overlapping channels (e.g. 1 & 6). What deployment flaw could cause this problem? (Choose 2)

Options

  • AThe access points are mounted too closely to one another.
  • BReflective objects in the area are causing significant multipath.
  • CA client station is using active scanning to probe for access points on multiple channels.
  • DThe output power on the access points is too high.
  • EA client station authenticates to both access points, but does not associate.
  • FThe access points are not synchronized to the same NTP server.
