（A）The PCA packet comes out of the GigabitEthem1/0/port of SWA and enters the GigabitEthem1/0/4 port of SWB. The VLAN tag carried is VLAN20

（B）SWB packets enter from SWA's GigabitEthem1/0/3 port, and after exiting from GigabitEthem1/0/3 port, the VLAN Tag carried is VLAN20

（C）When SWB accesses PCA, the VLAN tag carried by GigabitEthem1/0/4 of SWB is VLAN 10

（D）The PCA packet enters from the GigabitEthem1/0/1 port of SWA, and the VLAN tag after exiting from the GigabitEthem1/0/3 port is VLAN2

（A）Switch SWH uplink switch SWD and SWE links are in Down state, then the main port of the switch SWJSmart Link group will be switched to the secondary port

（B）Switch SWJSmart Link group status has nothing to do with switch SWH

（C）Switch SWH upstream switch SWD link is Down, then the main port of the switch SWJSmart Link group will be switched to the secondary end

（D）The switch SWH uplink switch SWE link is Down, then the main port of the switch SWJSmart Link group will be switched to the secondary port

（A）SWB port E0/2 is the designated port

（B）SWD port E0/2 is the root port

（C）SWC will forward configuration BPDUs from port E0/3 to SWD

（D）SWA is the root bridge in the network

（A）00E0.FC00.0020

（B）00E0.FC00.0010

（C）0011.1111.1111

（D）FFFF.FFFF.FFFF

（A）Graft

（B）Graft-ACK

（C）Hello

（D）Assert

（E）Prune

（F）Join

（A）After the STP converges, connect the SWD to the network through the dotted link 1 in the figure, then the SWD will first send the configuration BPDU with itself as the root, and after the longest Hello Time, the SWC will send the SWD the configuration with the SWA as the root BPDU

（B）Before joining SWD, after STP converges, SWC will receive configuration BPDUs from both E0/1 and E0/2

（C）Before joining SWD, after STP convergence, SWB port E0/2 is an alternate port

（D）After the STP converges, connect the SWD to the network through the dotted link 1 in the figure, and the SWD will first send the configuration BPDU with itself as the root, and the SWB will immediately respond to the configuration BPDU with the SWA as the root.

（A）MACVLAN Port VLAN Protocol VLAN Subnet VLAN

（B）Port VLAN IP Subnet VLAN Port VLAN MAC VLAN

（C）MACVLAN subnet VLAN protocol VLAN port VLAN

（D）Port VLAN MACVLAN Protocol VLAN IP Subnet VLAN

（A）If sub-ring 2 and sub-ring 3 are added to the same ring group, the main ring link corresponding to the edge node and assistant edge node of sub-ring 2 and sub-ring 3 in the ring group should be the same

（B）If sub-ring 2 and sub-ring 3 are added to the same ring group, the edge node and assistant edge node of sub-ring 2 and sub-ring 3 in the ring group can be different

（C）If sub-ring 2 and sub-ring 3 are added to the same ring group, the ring group should be configured on the switch SWB, SWC, SWE, SWF, and the configuration should be consistent

（D）Cannot add sub-ring 2 and sub-ring 3 to the same ring group

（A）As long as the network topology and unicast routing information remain unchanged, the formed SPT tree will not change

（B）The pruned interface no longer sends multicast packets downstream

（C）The diffusion-pruning process is carried out periodically

（D）After the process of flooding and pruning, an SPT between the multicast source and the multicast receiver is formed

（A）When SWC edge port E0/1 is connected to a PC, SWC will send RST BPDU with TC set

（B）As shown in the figure, when SWB is connected to another switch running RSTP, SWD will send RSTBPDU with TC set.

（C）When the link between SWB and SWC is down, both SWB and SWC will send RST BPDU with TC set

（D）As shown in the figure, when SWB is connected to another switch SWD running RSTP, SWB will send RSTBPDU with TC set

（A）RT1

（B）RT2

（C）RT3

（A）RTA is the master router of the backup group

（B）After RTA is sent, RTB is the master router of the backup group

（C）RTC is the master router of the backup group

（D）RTB is the master router of the backup group
