As shown in the following figure, switch A and router A are connected through two links. The two links are aggregated in manual load balancing mode. The aggregation port number is 1. The aggregated link needs to carry VLAN tag 100. Switch A uses the trunk link.
Which of the following configurations need to be performed on switch A?
A.
B.
C.
D.
To connect switch A to router A through two aggregated trunk links that must carry VLAN tag 100, the switch configuration should fulfill several criteria: it needs to establish the link aggregation, set the port link-type to trunk, and specify the VLAN to be carried. Based on these requirements, the correct configuration should include setting up the Ether-Trunk interface, configuring the member interfaces to be part of this Ether-Trunk, setting the link type to trunk, and allowing the specific VLAN. Therefore, the best configuration for this scenario is: 'C'. This includes configuring the Eth-Trunk interface, setting the link type to trunk, specifying the allowed VLAN (in this case, VLAN 100), and including the member interfaces in the Eth-Trunk. The 'B' configuration is almost correct but includes 'mode lacp-static', which isn't necessary for manual load balancing mode. Thus, option 'C' is the best fit for the given requirements.
c is the correct answer
