Detailed Explanation:The command forward-mode direct-forward is used to configure the AC to enable direct forwarding, meaning that the AP will forward user data packets directly to the network without tunneling them through the AC, improving efficiency by reducing the load on the AC​.

Comprehensive Explanation: Netstream is a protocol for flow-based network traffic analysis, not a method for logging into a VRP system. The valid methods for accessing the VRP system include Telnet, Web, and SSH, which are used for remote management and configuration of network devices​

Switches generally operate at the data link layer (Layer 2) and are used to manage communication within a local area network (LAN) by directing traffic among devices. They are not usually deployed as egress devices, which are typically routers. Switches facilitate internal LAN communication, while egress devices handle traffic leaving the network​.

Comprehensive Explanation: To remove the Eth-Trunk interface, you can simply use the undo interface Eth-Trunk 1 command. This command deletes the entire Eth-Trunk interface from the switch configuration. The other commands involve additional steps to unbind physical interfaces from the Eth-Trunk, but these steps are unnecessary if you are deleting the Eth-Trunk interface entirely.

TPID Definition:

TPID (Tag Protocol Identifier) is a field in the Ethernet frame header that indicates the presence of an 802.1Q VLAN tag.

IEEE 802.1Q defines the TPID value as 0x8100.

Why Other Options Are Incorrect:

0x9100: Used in some proprietary protocols but not IEEE standard.

0x8200 and 0x7200: Not valid TPID values.

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.

The Forward Delay timer in STP helps prevent temporary loops by setting a delay for ports transitioning through Listening and Learning states before reaching the Forwarding state. This wait period ensures that all switches have updated topology information, reducing the risk of broadcast storms or loops​.

Comprehensive and Detailed Explanation:

BPDU (Bridge Protocol Data Unit) packets are exchanged only on ports in Blocking, Listening, and Learning states.

Ports in Forwarding state DO NOT receive BPDU packets (BPDUs are only processed by non-designated ports).

If a forwarding port starts receiving BPDUs, it goes back to Listening state to re-evaluate STP topology.
