Regarding the comparison of unicast, multicast and broadcast, there are correct

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 As the Secondary VLAN of VLAN20, after setting the IP address of each device as shown in the figure, check the MAC address table on the SWA, and you can determine that the PCC belongs to

Two routers RTA and RTB are connected through a LAN to form a VRRP backup group. The interface configuration of each router is as follows:
GigabitEthernet1/0 of RTA
ip address 192.168.0.252 255.255.255.0
ip address 192.168.1.252 255.255.255.0 sub
vrrp vrid 1 virtual-ip 192.168.0.254
vrrp vrid 1 priority 120
vrrp vrid 2 virtual-ip 192.168.1.254
GigabitEthernet1/0 of RTB
ip address 192.168.0.253 255.255.255.0
ip address 192.168.1.253 255.255.255.0 sub
vrrp vrid 1 virtual-ip 192.168.0.254
vrrp vrid 2 virtual-ip 192.168.1.254
vrrp vrid 2 priority 120
From the above information-know

In the PIM-DM network as shown in the figure, part of the unicast routing table of routers RT1 and RT2 is as follows

Then, the (S, G) entry and exit interface lists of routers RT1 and RT2 are respectively

In the network shown in the figure, the switch SWA is a two-layer switch, and the router RTA is the gateway of each PC. The following configuration is made on the router RTA:
[RTA]interface Ethernet 0/0.1
[RTA-Ethernet0/0.1]ip address 10.10.10.1 255.255.255.0
[RTA-EthernetO/0.1 ]vlan-type dotlq vid 1

After completing the phase configuration on the switch SWA, PCA, PCB and PCC can all ping their own gateway. The following is correct about the switch SWA port Ethernet1/0/4 (choose one or more)
