  1. 2.4 GHz surveys for voice—data rates:

    Disable rates under 12 Mbps.

    If you have no 802.11b clients, disable data rates of 1, 2, 5.5, 6, 9, and 11 Mbps.

    Basic (required) data rate is 12 Mbps.

    If 802.11b clients exist, disable data rates of 1, 2, 5.5, 6, and 9 Mbps.

    Basic (required ) data rate is 11 Mbps.

    Set only the lowest data rate as the single basic rate for multicast traffic.

    Capacity and throughput are reduced when lower rates are enabled.

      1. No, You don’t need the data rates below 11 Mbps to support 802.11b. If we have just the 11 Mbps supported and Set the mandatory data rate to 11 Mbps, 802.11b clients would be able to connect. A and B are correct answers
