Regarding the multicast distribution tree model SPT, the correct statement below is ______.

• A.Different multicast sources take themselves as the root and establish SPT independently
• B.Each router on the SPT will maintain (*, G) entries
• C.In the SPT model, the path taken by the multicast source to reach any receiver is optimal
• D.Each router on the SPT will maintain (S, G) entries

Regarding the description of Isolate-user-vlan technology and Super VLAN technology, the following is correct

• A.SuperVLAN technology is also called VLAN aggregation: the main purpose is to solve the waste of IP addresses or insufficient number of VLAN interfaces
• B.Isolate-user-vlan is a Layer 2 VLAN technology, so switches that support isolate-user-vlan technology are Layer 2 switches
• C.SuperVLAN is a three-layer VLAN technology, so all switches that support Super VLAN technology are three-layer switches

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
1.1.1.0/24xxxxP1-1 C1-110.1.1.1POI11
1.1.0.0/16xxxxP1-2 C1-210.1.1.1Port1
<RT2>display ip routing-table
Routing Tables: Public

• A.If P1-1= P2-2,
• B.If P1-1 = P2-2,
• C.If P1-1> P2-2,
• D.If P1-2>P2-2,
• E.If P1-2 = P2-2,
• F.If P1-2 = P2-2,

The topology is shown in the figure, and the STP calculation is performed. The correct result is

• A.SWA is the root bridge in the network
• B.SWD port E0/2 is the root port
• C.SWC will forward configuration BPDUs from port E0/3 to SWD
• D.SWB port E0/2 is the designated port

In the switching network as shown in the figure, VLAN10 is set as SuperVLAN on the switch SWA, and VLAN2 and VLAN3 are Sub VLANs of VLAN10. The PCA and PCB are required to communicate with each other. After the switch SWA configuration is completed, the PCA can ping the PCB. After that, regarding the ARP entries on the PCA, PCB and switch SWA, the correct description below is _ (choose one or more)

• A.None of the above is correct
• B.The ARP entry learned on PCA is: Internet AddressPhysical AddressType 10.1.1.2 0022-2222-2222 dynamic
• C.The ARP table entry learned on the PCB is: Internet AddressPhysical AddressType 10.1.1.1 00E0-FC0A-0010 dynamic
• D.The ARP i item learned on SWA is: IP Address MAC Address VLAN ID InterfaceAging Type 10.1.1.1 0011-1111-11112Eth1/0/1 20D 10.1.1.2 0022-2222-22223Eth 1/0/2 20D
