The following statements about the DR election process of the PIMSM shared network segment are correct:

The customer's two switches SWA and SWB are connected together through seven Ethernet cables and configured with dynamic link aggregation. The corresponding ports on the switch SWA are Ethernet 1/0/1, Ethernet 1/0/2, and Ethernet 1/0. /3, Ethernet 1/0/4, Ethernet 1/0/5, Ethernet 1/0/6, Ethernet 1/0/7o If the switches SWA and SWB only support 6 ports per aggregation group, and the SWA switch has the following Configuration:
[SWA]interface Ethernet 1/0/7
[SWA-Ethernet1/0/7]lacp port-priority 4096
Check LACP status on the device: output letter: as follows:
[SWA]display lacp system-id
Actor System ID: 0x8000, 00e1-fc00-5000
[SWB]display lacp system-id
Actor System ID: 0x8000, 00e0-fc43-7384
If you change SWA's LACP system priority to 4096, you can know from the above information

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

In the switching network shown in the figure, VLAN10 is set as Isolate-user-vlan on the switch SWA, VLAN2 and VLAN3 are set as the Secondary VLAN of VLAN 10; VLAN2? VLAN20 is created on the switch SWB, and VLAN20 is set as Isolate-user-vlan , VLAN4 is VLAN20 Secondary VLA after setting the IP address of each device as shown in the figure, the local proxy ARP function is enabled on both SWA and SWB. At first, the switch and pc did not learn their corresponding ARP entries in PCA. During the process of pinging PCB, PCA will send an ARP request. The source MAC address of the ARP request packet forwarded by the switch to PCB is

In the switching network as shown in the figure, set VLAN10 to Isolate-user-vlan VLAN2 and VLAN3 to the Secondary VLAN of VLAN 10 on the switch SWA; create VLAN2? VLAN20 on the switch SWB, and set VLAN20 to Isolate-user-vlan, The Secondary VLA with VLAN4 being VLAN20 can be judged after setting the IP address of each device as shown in the figure

正解：C,D,E 解答を投票する
Regarding the three versions of the multicast group management protocol IGMPv1, IGMPV2, and IGMPv3, which is correct

正解：A,B,D,E 解答を投票する
When the IGMPV2 host leaves a multicast group, it will send a LeaveGroup message, which is correct as follows:

Which statement about the STP protocol is 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 For the Secondary VLA of VLAN20, after setting the IP address of each device as shown in the figure, which of the following statements is correct (choose one or more)

In the network shown in the figure, the PIM SM protocol runs between RT1, RT2 and RT3, the RP is 1.1.1.1 RT3 is connected to the receiver, and IGMP is enabled on the corresponding interface to view the unicast routing table in RT3 as follows:
[RT3]display ip routing-table
Routing Tables: Public
Destinations: 10 Routes: 10
Destination/MaskProtoPreCost NextHop Interface
1.1.1.1/320SPF 10 1562 192.168.2.1 so/2/1

Then, when the receiver (Receiver) sends a group join request, which of the following routers have (*, G) entries

Two routers RTA and RTB are connected through a LAN to form a VRRP backup group. The IP address of HostA in the LAN is 192.168.0.1, and the gateway MAC address that HostA learned is 0000-5e00-0105. From the above information, we can know

The core goal of highly reliable redundant network design is
