The correct answer is B. 802.11b. The maximum throughput of each 802.11 standard is the key fact here: 802.11b = 11 Mbps, 802.11a = 54 Mbps, 802.11g = 54 Mbps, and 802.11n = up to 600 Mbps (commonly 150–300 Mbps). Because the laptop can only reach 11 Mbps, its WLAN card must be an 802.11b card. Even though the…

Question

A technician is installing an 802.11n network. The technician is using a laptop that can connect at a maximum speed of 11 Mbps. The technician has configured the 802.11n network correctly but thinks it could be the type of WLAN card used on the laptop. Which of the following wireless standards is the WLAN card MOST likely using?

Options

A802.11a
B802.11b
C802.11g
D802.11n

Explanation

The maximum throughput of each 802.11 standard is the key fact here: 802.11b = 11 Mbps, 802.11a = 54 Mbps, 802.11g = 54 Mbps, and 802.11n = up to 600 Mbps (commonly 150–300 Mbps). Because the laptop can only reach 11 Mbps, its WLAN card must be an 802.11b card. Even though the access point supports 802.11n, an 802.11b client will negotiate at the highest speed both devices share, which is 11 Mbps. This is a classic backward-compatibility scenario - older clients connect at their own maximum speed.
