In addition to avoiding 2.4 GHz channels and installing a distributed spectrum analyzer to locate RF interference sources, what should the implementer do to resolve the problem fully?

ABC Manufacturing has a heavily-used dual-band (2.4 / 5 GHz) WLAN, but sporadic RF interference across the 2.4 GHz band is causing dropped VoWiFi calls and leading to data connectivity and throughput problems.

In addition to avoiding 2.4 GHz channels and installing a distributed spectrum analyzer to locate RF interference sources, what should the implementer do to resolve the problem fully?
A . Have only guest access on the 5 GHz channels.
B . Move all corporate data clients and VoWiFi devices to the 5 GHz channels appropriate for their regulatory domain.
C . Use captive portals for guest authentication in 5 GHz.
