Given: 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 two)

A.
The access points are mounted too closely to one another.

B.
Reflective objects in the area are causing significant multipath.

C.
A client station is using active scanning to probe for access points on multiple channels.

D.
The output power on the access points is too high.

E.
A client station authenticates to both access points, but does not associate.

F.
The access points are not synchronized to the same NTP server.
