In the switching network shown in the figure, set VLAN10 as Isolate-user-vlan on switch SWA, and VLAN2 and VLAN3 as Secondary VLAN of VLAN 10; create VLAN4 and VLAN20 on switch SWB, and set VLAN20 as Isolate-user-vlan, and VLAN4 as Secondary VLAN of VLAN20. After setting the IP addresses of each device as shown in the figure, check the MAC address table on SWA, and you can determine that PCC belongs to which of the following?

• A.  VLAN 4
• B.  VLAN 1
• C.  VLAN 3
• D.  VLAN 10
• E.  VLAN 2
• F.  VLAN 20

The customer LAN switches SWA, SWB, and SWC form the RRPP ring main ring 1. The switch SWB has the following configuration information:
[SWB] rrpp domain 1
[SWB-rrpp-domain1] ring 1 node-mode transit primary-port gigabitethernet 2/0/1 secondary-port gigabitethernet 2/0/2 level 0 If switch SWA is the master node of primary ring 1, and if switch SWB port GigabitEthem2/0/1 fails, what can we learn from the above information? (Multiple choice)

• A.  If switch SWB finds that port GigabitEthernet 2/0/1 is Up again, it will immediately unblock the port.
• B.  SWA will send a Link-Down message to notify all nodes
• C.  The switch SWA will send a Common-Flush message to notify all transmission nodes
• D.  The switch SWA immediately switches to the Failed state and releases the secondary port

In PIM-DM networking, which of the following is correct about the router sending the Prune message?

• B.  After the router interface receives the Prune message, it will no longer send messages of the corresponding multicast group on this interface.
• C.  The party that fails the Assert will send a
• D.  When the router has no local directly connected multicast receiver, it sends a Prune message to all PIM neighbors.
