Pearson H12-811_V1.0 New Attempt

Comprehensive Explanation: In this configuration, LSW1 and LSW2 have trunk links that allow VLAN 10 to pass between them. When a ping is sent from R1, the frame is tagged with VLAN 10 on LSW2, and this tagged frame is forwarded to LSW1. Since the trunk allows VLAN 10, the tagged data frame is successfully received and processed by LSW1.

An access port is a switch port assigned to a single VLAN and used to connect end devices (such as PCs or printers).

Access ports do not send VLAN tags. They remove the VLAN tag before forwarding frames to the connected device because most end devices do not support VLAN tagging.

Option A (Incorrect): Tagged frames are sent only by trunk ports, not access ports.

Option B (Correct): The access port strips the VLAN tag before forwarding the frame to ensure compatibility with non-VLAN-aware devices.

Option C (Incorrect): VLAN tags are not exchanged between inbound and outbound ports.

Option D (Incorrect): The access port does not attach PVID information to the frame when sending it out.

Thus, the correct answer is B.

Comprehensive Explanation: The " -i " parameter in the Ping command on Huawei VRP (Versatile Routing Platform) is used to specify the source IP address for sending an Echo Request (ping) packet. This is useful in cases where the router has multiple interfaces and you want to control which interface is used to initiate the ping. By defining the source IP address, the ping request can be sent from a specific interface on the router, enabling network administrators to test connectivity from that interface.
