N10-005 Question #911: Real Exam Question with Answer & Explanation

The correct answer is A: 802.11a. 802.11a operates in the 5 GHz frequency band, which provides up to 23 non-overlapping channels (varies by regulatory domain). In contrast, 802.11b operates in the 2.4 GHz band, which has only 3 non-overlapping channels (1, 6, and 11). 802.11i is a security standard (WPA2), not a

Question

Which of the following technologies has more non-overlapping channels to utilize in a wireless LAN?

Options

A802.11a
B802.11b
C802.11i
DBluetooth

Explanation

802.11a operates in the 5 GHz frequency band, which provides up to 23 non-overlapping channels (varies by regulatory domain). In contrast, 802.11b operates in the 2.4 GHz band, which has only 3 non-overlapping channels (1, 6, and 11). 802.11i is a security standard (WPA2), not a frequency/channel specification. Bluetooth also uses the 2.4 GHz band with frequency hopping, not fixed channels. The wider 5 GHz spectrum of 802.11a is a key advantage for dense wireless deployments.
