    Correct Answer
    B. 802.11
    Explanation
    The correct answer is 802.11. This family of specifications refers to the set of standards for wireless local area networks (WLANs) developed by the IEEE.

    Which of the following refers to a standard or group of standards that are still being developed as a part of overall IEEE 802.11 WLAN support?

    • A.

      802.11x

    • B.

      802.11i

    • C.

      Both of the above

    • D.

      Neither of the above

    Correct Answer
    C. Both of the above
    Explanation
    Both 802.11x and 802.11i refer to standards that are still being developed as part of the overall IEEE 802.11 WLAN support. The "x" in 802.11x represents a placeholder for various extensions and amendments to the original 802.11 standard, which are continuously being developed. On the other hand, 802.11i specifically focuses on security enhancements for wireless networks. Therefore, both options refer to ongoing developments within the IEEE 802.11 WLAN support.
