In the networking shown in the figure, the PIM SM protocol runs between RT1, RT2, and RT3, the RP is 1.1.1.1 There is a multicast source connected to the downstream interface of RT1 and RT2, and there are downstream receivers on the RP, then when the RP sends After registering the stop message, which of the following routers have (S, G) entries

• A.RT3
• B.RT1
• C.RT2

The three routers RTA, RTB, and RTC are connected together via a LAN to form a VRRP backup group. The interface configuration of each router is as follows:
RTA's GigabitEthernet ip address 192.168.0.252 255.255.255.0 vrrp vrid 1 virtual-ip 192.168.0.254 vrrp vrid 1 priority 120 RTB's GigabitEthernet ip address 192.168.0.253 255.255.255.0 vrrp vrid 1 virtual-ip 192.168.0.254 vrrp vrid 1 priority 90 RTC's GigabitEthernet ip address 192.168.0.254 255.255.255.0 vrrp vrid 1 virtual-ip 192.168.0.254
It can be known from the above information

• A.RTC is the master router of the backup group
• B.RTB is the master router of the backup group
• C.After RTA is sent, RTB is the master router of the backup group
• D.RTA is the master router of the backup group

In the PIM-DM networking, about the router sending Prune (prune) message, the description is correct:

• A.After the router interface receives the Prune message, it will no longer send packets of the corresponding multicast group on this interface
• B.Assert (assertion) the losing party will send to the winning party
• C.When the router has no local directly connected multicast receivers, it will send Prune to all PIM neighbors
• D.When the outgoing interface list in the router (S, G) table entry is empty, Prune messages will be sent to all PIM neighbors

In the switching network as shown in the figure, set VLAN10 as Isolate-userW VLAN2 and VLAN3 as the Secondary VLAN of VLAN 10 on the switch SWA; create VLAN2? VLAN20 on the switch SWB, and set VLAN20 as Isolate-user-vlan, VLAN4 For the Secondary VLAN of VLAN20, after setting the IP address of each device as shown in the figure, which statement is correct (choose one or more)

• 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

In the switching network as shown in the figure, VLAN 10 is set as Super VLAN on the switch SWA, VLAN 2 and VLAN 3 are Sub VLANs of VLAN 10, Port Ethernet1/0/3 is Trunk port, PVID is VLAN 1, allowing all VLANs to pass ; Create VLAN2~VLAN20 on the switch SWB, port Ethernet1/0/4 as Trunk port, PVID is VLAN1, allowing all VLANs to pass, after setting the IP address of each device as shown in the figure, check the MAC address table on SWB , It can be judged that PCA belongs to

• A.VLAN 1
• B.VLAN3
• C.VLAN2
• D.VLAN 10
