Why each option
The 802.11ac wireless networking protocol exclusively broadcasts at 5GHz frequencies, offering higher bandwidth and less interference than 2.4GHz bands. Other common protocols like 802.11b and 802.11g operate solely on the 2.4GHz band.
The 802.11ac standard operates exclusively on the 5GHz frequency band, providing significantly higher throughput and typically less interference compared to the crowded 2.4GHz band.
The 802.11b standard operates only on the 2.4GHz frequency band.
The 802.11g standard operates only on the 2.4GHz frequency band.
802.11q is not a wireless networking protocol for frequency bands; it refers to the IEEE 802.1Q standard for VLAN tagging in Ethernet networks.
802.11x is not a wireless networking protocol for frequency bands; it is often confused with 802.1X, an IEEE standard for port-based Network Access Control used for authentication.
Concept tested: Wi-Fi frequency bands (802.11 standards)
