220-801 Question #260: Real Exam Question with Answer & Explanation

The correct answer is A: A. IEEE 802.11a operates exclusively on the 5GHz frequency band and provides a maximum theoretical throughput of 54Mbps. Because 5GHz was less crowded when 802.11a was introduced, it offered less interference than the 2.4GHz band. 802.11b operates at 2.4GHz with a maximum of 11Mbps.

Question

Which of the following 802.11 standards has a MAXIMUM bandwidth throughput of 54Mbps and uses 5GHz frequency?

Options

Explanation

IEEE 802.11a operates exclusively on the 5GHz frequency band and provides a maximum theoretical throughput of 54Mbps. Because 5GHz was less crowded when 802.11a was introduced, it offered less interference than the 2.4GHz band. 802.11b operates at 2.4GHz with a maximum of 11Mbps. 802.11g operates at 2.4GHz with a maximum of 54Mbps - it matches 802.11a in speed but uses the more congested 2.4GHz band. 802.11n operates on both 2.4GHz and 5GHz and achieves speeds up to 600Mbps using MIMO technology.
