Detailed Explanation:In a Layer 2 WLAN, an Access Controller (AC) typically handles authentication and management but does not act as a gateway. Instead, a Layer 3 device, such as a router, serves as the gateway. (Reference: HCIA-WLAN Training Material, WLAN Layer 2 and Layer 3 Concepts)

Comprehensive Explanation: The interface configuration shows that VLANs 2, 3, and 100 are tagged, meaning frames belonging to these VLANs are transmitted with VLAN tags. VLANs 4 and 6 are untagged, meaning frames for these VLANs are transmitted without tags. The command port hybrid tagged vlan 2 to 3 100 specifies that data frames for VLANs 2, 3, and 100 are transmitted with tags, while port hybrid untagged vlan 4 6 configures the interface to transmit untagged frames for VLANs 4 and 6.

Detailed Explanation:In NAPT, port numbers are dynamically assigned as traffic flows through the router. The port number range is automatically selected, and manual configuration of each mapping is not required. NAPT dynamically uses different ports for mapping private IP addresses to a single public IP address​​.

Comprehensive Explanation: The IEEE 802.11g standard operates exclusively in the 2.4 GHz frequency band, offering data rates up to 54 Mbps. Other standards, such as 802.11a, operate in the 5 GHz band, while 802.11n and 802.11ax support both 2.4 GHz and 5 GHz frequency bands, making 802.11g the only standard in this list that is limited to 2.4 GHz.
