Based on the port configuration in a Huawei switch, which statement is correct?

The correct answer focuses on the behavior of the switch concerning VLAN tags. In VLAN configurations, switches can be set to recognize specific VLAN IDs and handle tagged and untagged frames differently based on their port settings.

When a switch is configured to handle VLANs in a certain manner, it may be set to only forward specific VLAN IDs while dropping others. In this case, if the configuration specifies that data frames containing VLAN 17 tags are not permitted, the switch will not forward those frames, effectively dropping them from being transmitted further along the network.

The other options describe actions that do not align with typical VLAN handling practices for a switch that is configured to filter specific VLANs. For instance, frames with no tags can be processed in a default manner unless the configuration explicitly states that frames without tags should receive a VLAN tag or be explicitly permitted or dropped. Understanding the target VLAN settings and their implications is critical in managing data traffic effectively within a switched network environment.
