H12-811_V1.0 Huawei Exam Lab Questions

The BSSID (Basic Service Set Identifier) serves as the MAC address identifier for each Virtual Access Point (VAP) on an AP. Each BSSID uniquely identifies an SSID on a specific radio of an AP, allowing clients to associate with the correct access point in a multi-AP environment​.

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.

Trunk Interface Basics:

Trunk interfaces are used to carry traffic for multiple VLANs between switches.

Tagged frames include VLAN identifiers, while untagged frames belong to the native VLAN.

Untagged Frames:

Frames from the native VLAN are sent untagged on the trunk interface.

Conclusion:

Trunk interfaces support both tagged and untagged frames, so the statement is TRUE.
