Show Answer
Correct Answer: A,C

The clients that must support OFDMA must also be upgraded to 802.11ax. OFDMA is a key feature introduced with the 802.11ax (Wi-Fi 6) standard. To take advantage of OFDMA, both the access points and the client devices need to support the 802.11ax standard. Devices using older standards like 802.11ac cannot be upgraded via drivers to support OFDMA, as it requires hardware capabilities specific to 802.11ax.
