Huawei Updated H12-811_V1.0 Exam Questions and Answers by fallon

Detailed Explanation:Access ports are configured for a single VLAN and thus send untagged frames by default. Trunk ports, conversely, handle traffic for multiple VLANs, tagging each frame with a VLAN ID. (Reference: HCIA-Datacom Training Material, Switch Port Types and VLAN Tagging)

DHCP (Dynamic Host Configuration Protocol) can allocate various network parameters, including:

IP address: Assigns a unique IP to each client.

Gateway address: Provides the default gateway for routing traffic.

DNS server address: Allows domain name resolution. The DHCP server does not assign an operating system, as this is outside its scope​.

Comprehensive Explanation: In STP (Spanning Tree Protocol), the root bridge is elected based on the lowest Bridge ID. The Bridge ID consists of two parts: the bridge priority and the MAC address of the switch. The switch with the lowest Bridge ID is elected as the root bridge. If two switches have the same priority, the switch with the lowest MAC address becomes the root. Other parameters such as Port ID and Root path cost are used in subsequent decisions to determine the best paths to the root bridge, but they are not used in the root bridge election itself.
