An office area contains two PoE-enabled WAPs. After the area was remodeled, new cable uplinks were
installed in the ceiling above the fluorescent lights. However, after the WAPs were reconnected, users reported
slowness and application errors. An intern reviewed the network and discovered a lot of CRC errors. A network
engineer reviewed the intern's work and realized UTP cabling was used. Which of the following is the MOST
likely cause of the CRC errors?


A. Insufficient power at the antennas
B. PoE and UTP incompatibility
C. Electromagnetic interference
D. Wrong cable pinout
