H12-311_V3.0 · Question #251
Which of the following wireless local area network standards can the transmission rate reach 54Mbps and above? (Multiple choice)
The correct answer is A. 802.11a C. 802.11g D. 802.11n. Standards A (802.11a), C (802.11g), and D (802.11n) all achieve 54 Mbps or higher: 802.11a operates on the 5 GHz band at up to 54 Mbps, 802.11g operates on 2.4 GHz also at up to 54 Mbps, and 802.11n goes far beyond with speeds up to 600 Mbps using MIMO antenna technology on…

Explanation
Standards A (802.11a), C (802.11g), and D (802.11n) all achieve 54 Mbps or higher: 802.11a operates on the 5 GHz band at up to 54 Mbps, 802.11g operates on 2.4 GHz also at up to 54 Mbps, and 802.11n goes far beyond with speeds up to 600 Mbps using MIMO antenna technology on both bands.
B (802.11b) is wrong because it is an older 2.4 GHz standard capped at only 11 Mbps - well below the 54 Mbps threshold.
Memory tip: Think of the letters in order of speed - b is the slowpoke at 11 Mbps, while a and g are the "54 club," and n is the speed king. A useful mnemonic: "A and G hit 54, N blows past the door; B stays at 11 and can't keep score."
