Why is a high CRC error rate in L2 protocol analysis software NOT always a valid indicator of network performance? (Choose 3)

• A.If the protocol analysis radio hardware is not located in the same area as intended client devices or APs, its data sampling may not be representative of actual traffic on the network.
• B.Radio and antenna hardware used for protocol analysis may not match the receive sensitivity, diversity, MIMO, or antenna gain capabilities of the network WLAN hardware.
• C.Layer 2 protocol analysis can only collect and interpret data that is received properly at the MAC layer, and cannot quantify some PHY-layer problems.
• D.If protocol analysis software is not properly configured with frame decryption parameters, it can't accurately calculate a CRC, which includes the encrypted frame body contents.
