You are troubleshooting a problem with a new 802.11ax AP. While the AP supports four spatial streams, most clients are only achieving maximum data rates of 150 Mbps. What is the likely cause?

The correct answer is A. The clients are only two stream 802.11ax clients. In the CWNA-108 pg 132 The receiving device must have an equal number of radio chains to the transmitting device. For example, if the AP has four transmitting (Tx) and receiving (Rx) antennas, the client must also have four.
