In VRP, to enter the configuration view for a specific OSPF area, the syntax [Huawei-ospf-1] area 0.0.0.0 is used. This command specifies Area 0 in the correct format (dotted decimal notation) as required by VRP, which supports OSPF multi-area configuration by designating specific area views​.

TCP (Transmission Control Protocol) uses a three-way handshake process to establish a reliable connection between two devices, ensuring that data transmission is stable and reliable. The handshake sequence (SYN, SYN-ACK, ACK) confirms that both devices are ready to send and receive data, guaranteeing ordered and error-checked delivery. This characteristic makes TCP a reliable transport protocol​.

Detailed Explanation:When bridge priorities are identical, STP elects the switch with the lowest MAC address as the root. Here, Switch B has the lowest MAC address (00-e0-fc-00-00-10), making it the root switch. (Reference: HCIA-Datacom Training Material, STP Root Bridge Election)

Detailed Explanation:In a "one-armed routing" setup, a router with sub-interfaces can handle inter-VLAN routing by logically segmenting traffic within a single physical interface. In this configuration, each department (Administration and Finance) is assigned a different VLAN with separate sub-interfaces on Router R1.

In such a setup, communication between different VLANs (i.e., inter-VLAN routing) is handled by the router, even without Proxy ARP enabled. The router can directly route packets between the VLANs as it is aware of the different networks and performs Layer 3 forwarding based on the IP address of each VLAN's sub-interface.

Thus, even if ARP Proxy is disabled, devices in the Administration and Finance departments can communicate through the router because inter-VLAN routing takes place at Layer 3 without relying on ARP proxy functionality​​​.
