A. 802.11a B. 802.11b C. 802.11g D. 802.1x
Correct Answer: A
Explanation: In this question, we need a wireless network that operates at a frequency higher than the 2.4GHz frequency. 802.11 is a set of IEEE standards that govern wireless networking transmission methods. The 802.11 standards commonly used today to provide wireless connectivity in home or office wireless networks are 802.11a, 802.11b, 802.11g, 802.11n and 802.11ac. The 802.11a standard supports speeds up to 54Mbps and uses the 5-GHz band.
