In the switching network as 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, if the local ARP proxy function is enabled on both SWA and SWB, and both SWA and SWB are allowed to send ICMP packets, then on PCA Run the tracert 10.1.1.2 command, the PCA shows that the destination IP address reached by the first hop is

Before configuring the bpdu-tunnddotlq stp command on the port where the QinQ function of the H3C series switch is enabled, the command that must be configured on this port is

In the PIM-DM network as shown in the figure, part of the unicast routing table of routers RT1 and RT2 is as follows:
<RT1>display ip routing-table
Routing Tables: Public
Destination/MaskProtoPreCost NextHop Interface
1.1.0.0/16xxxxP1-1 C1-110.1.1.1POI11
1.1.1.0/24xxxxP1-2 C1-210.1.1.1Port1
<RT2>display ip routing-table
Routing Tables: Public
Destination/MaskProtoPreCost NextHop Interface
1.1.1.0/24XXXX P2-1 C2-111.1.1.1Port2
1.1.1.1/32XXXX P2-2 C2-211.1.1.1Port2
Then, when routers RT1 and RT2 perform Assert, the winner should be

• A.If P1-1=P2-2, C1-1=C2-2, RT1 wins
• B.If P1-2>P2-2, C1-1<C2-2, RT2 wins
• C.If P1-1=P2-2, C1-1<C2-2, RT1 wins
• D.If P1-1>P2-2, C1-1<C2-2, RT1 wins
• E.If P1-2=P2-2, C1-2<C2-2, RT2 wins
• F.If P1-2=P2-2, C1-2=C2-2, RT2 wins

When configuring MSTP, the configuration steps of area view include

• A.Use the region-name command to configure the domain name
• B.Configure the mapping between VLANs and instances
• C.Use the revsion command to configure the revision level
• D.Configure the preferred root bridge and backup root bridge of the instance
