Question 2

Regarding the spanning tree port cost configuration of H3C switches, which of the following is correct? (Multiple choice)

A. By default, the larger the port cost value, the smaller the port bandwidth B. The default spanning tree port cost standard followed by H3C switches is legacy C. If switches from different manufacturers are interconnected, the switches should be configured to follow the same port cost standard as much as possible, otherwise the spanning tree calculation results may deviate from the original intention of the network design. D. H3C switches support three port cost standards: dot1d-1998, dot11, and legacy. The stp pathcost- standard command can be used to switch the port cost standard.

Question 3

Which of the following statements about the principle of SmartLink & Monitor Link is correct?

A. MonitorLink sends Flush messages to notify other devices to refresh the MAC address forwarding table and ARP table entries. B. SmartLink sends Flush messages to notify other devices to refresh MAC address forwarding entries and ARP entries. C. MonitorLink implements redundant backup of the primary and backup links, and enables traffic to be quickly switched to the backup link when the primary link fails. D. SmartLink is a port linkage solution that monitors the device uplink. The Up/Down status change of the uplink triggers the Up/Down change of the downlink.

Question 14

Regarding the relationship between SuperVLAN and Sub VLAN, which of the following descriptions is correct? (Multiple choice)

A. Sub VLAN only contains physical ports, and the internal host uses the Super VLAN interface address as the gateway B.
