質問 2：
Which of the following description about the classification of link aggregation are wrong? (Multiple Choice)
A. In static LACP mode, the establishment of an Eth-Trunk and the joining of member interfaces are all manually configured. But with manual load sharing The difference in mode link aggregation is that LACP packets in this mode participate in the selection of active interfaces.
B. In dynamic LACP mode, the establishment of an Eth-Trunk, the joining of member interfaces, and the selection of active interfaces require manual configuration.
C. According to whether the link aggregation control protocol is enabled, it is divided into manual load sharing mode link aggregation and LACP protocol link aggregation.
D. In active LACP mode, all active interfaces participate in data forwarding and share load traffic. Therefore, they are called load balancing mode.
正解：B,D

質問 4：
In a company network environment, there are two switches SWA and SWB. The link aggregation LACP mode is adopted between the SWA and the SWB. There are three links added to the link aggregation, and the maximum number of active links is set to two. The system priority of the SWA is 4096. The system priority of the SWB is 32768. The interfaces of the three SWA links are G0/0/1, G0/0/2, and G0/0/3. The priority of the interface is 10, 20, 30. The interfaces of the three SWB links are G0/0/1, G0/0/2, and G0/0/3. The priority of the interface is 30, 20, and 10 respectively.
Which of the following conclusions are correct? (Multiple choice)
A. SWA is active
B. SWB G0/0/2 and G0/0/3 are active interfaces
C. SWA G0/0/1 and G0/0/2 are active interfaces
D. SWB is active
正解：A,C

質問 5：
The following configuration commands for issuing default routes for each protocol, which is wrong?
A. In a static route, the ip route-static default-preference command is used to generate a default route on the current router.
B. In the BGP protocol, the default-route imported command is used to enable the default route to be imported into the BGP routing table.
C. In the RIP protocol, the default route originate command is used to generate a default route on the current router or send the default route in the routing table to the neighbor.
D. In OSPF, the default route-advertise command is used to advertise the default route to the common 0SPF area.
正解：A

質問 6：

A. The result of the ExchangeDone event in the Exchange state is the state transition to Loading.
B. The result of the ExchangeDone event in the Exchange state is the state transition to Exstart.
C. The result of the NegotiationDone event in the Exstart state is the state transition to Full.
D. The result of the Loading Done event in the Loading state is the state transition to Full.
