In the network connection as shown in the figure, SWA and SWB are Layer 3 switches, running STP+VRRP, and after the initial configuration is completed, SWA is the root of STP and Master SWC of VRRP is the Layer 2 switch, which is connected to the following terminals. The description about the network link failure is correct

• A.When only the link between SWB and SWC is intact in the figure, the VRRP Master will remain unchanged, but the SWC downstream terminal cannot communicate with the gateway
• B.When the link between SWB and SWC is interrupted, VRRP Master will remain unchanged, and SWC downstream terminals can still communicate normally
• C.When the link between SWB and SWC is interrupted, the port status on the remaining STP links remains unchanged, and Forwarding is still maintained
• D.When only the link between SWB and SWC is intact in the figure, both SVVA and SWB will become VRRP masters, and the lower end of SWC can communicate with the gateway normally.

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 two routers are connected through the LAN to form a VRRP backup group. The VRRP timer configuration on each interface is as follows:
[RTA-GigabitEthernet1/0]vrrp vrid 1 timer advertise 5
[RTB-GigabitEthernet1/0]vrrp vrid 1 timer advertise 5
VRRP backup group 1 is operating normally, RTA is the Master and RTB is the Backup. If the router RTA fails after the device runs for a period of time, the time for the router RTB to change from Backup to Master may be

• A.20 seconds
• B.3 seconds
• C.12 seconds
• D.5 seconds

In the switching network as shown in the figure, VLAN10 is set as Isolate-user-vlan on switch SWA, VLAN2 and VLAN3 are set as Secondary VLAN of VLAN 10; VLAN2-VLAN20 is created on switch SWB, and VLAN20 is set as Isolate-user-vlan , VLAN4 is the Secondary VLAN of VLAN20. 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. Initially, the switch and pc did not learn their corresponding ARP entries. In the process of PCA ping PCB, PCA will send an ARP request. After receiving the ARP request message, the PCA will send the destination MAC response. The destination MAC address is

• A.FFFF.FFFF.FFFF
• B.0011.1111.1111
• C.00E0.FC00.0010
• D.00E0.FC00.0020

As shown in the diagram, SWA, SWB and SWC enable STP. If the bridge priority of SWA is set to 61440 after topology convergence, the following statements are correct.

• A.The topology will re-converge after 30 seconds by default
• B.After the priority is adjusted, SWA will still send configuration BPDUs with itself as the root.
• C.After the configuration BPDU saved locally by the SWB ages, it will send the configuration BPDU rooted to the SWA
• D.After SWC receives a low priority configuration BPDU, it will immediately respond to a configuration BPDU with itself as the root
