Company ABC is implementing a point-to-point bridging solution to a building approximately 3
kilometers (1.86 miles) away. The equipment used will be two autonomous access points set to
frequency 2412 Mhz with external antennas. The bridge link will be authenticated using an external
RADIUS server. While looking at the interface statistics, the network administrator observes
duplicate frames in the receive counters. What is most likely the root cause of these duplicate
frames?
A.
The antennae are not installed on the primary port.
B.
The counters on interface dot11radio1 are most likely due to the RF signal being corrupted by an
outside interference source.
C.
The non-root bridge is failing the authentication process and, as a result, sending and receiving
intermittently.
D.
The distance parameter is not configured.
E.
There is no clear LOS between the two buildings. The access points need to be mounted on higher
masts to obtain the proper clearance.
