In the switching network as shown in the figure, VLAN10 is set as Super VLAN on switch SWA, VLAN2 and VLAN3 are Sub VLAN of VLAN10, port Ethernet1/0/3 is Trunk port, PVID is VLAN1, allowing all VLANs to pass through; Create VLAN2~VLAN20 on SWB, port Ethernet1/0/4 as Trunk port, PVID is VLAN1, allowing all VLANs to set the IP address of each device as shown in the figure, check the MAC address table on SWA, you can judge PCC belongs to

• A.VLAN 10
• B.VLAN 1
• C.VLAN 3
• D.VLAN 2

In the switching network as shown in the figure, VLAN 10 is set as Super VLAN on the switch SWA, VLAN 2 and VLAN 3 are Sub VLANs of VLAN 10, Port Ethernet1/0/3 is Trunk port, PVID is VLAN1, allowing all VLANs to pass ; Create VLAN2~VLAN20 on the switch SWB, port Ethernet1/0/4 as Trunk port, PVID as VLAN1, allowing all VLANs to pass. After setting the IP address of each device as shown in the figure, you can judge (choose one or more item)

• A.SWA can communicate with PCC
• B.SWA can communicate with SWB
• C.SWA can communicate with PCB
• D.SWA can communicate with PCA

The customer's LAN switch SWA dual-uplink connection switch SWB and switch SWC, through SmartLink to ensure link reliability SWA switch has the following configuration:
[SWA-smlk-group1]smart-link flush enable control-vlan 10
The SWB switch has the following configuration?
[SWB-GigabitEthernet1/0/1]smart-link flush enable control-vlan 100
The SWC transfer machine has the following configuration:
[SWC-GigabitEthernet1/0/1]smart-link flush enable control-vlan 100
If the switch SWA switch SWB switch SWC interconnect interface allows all VLANs to pass, you can know from the above information

• A.No need to modify any configuration, SWA switch SmartLink backup function can be realized
• B.Without changing the configuration, the SmartLink backup function of the SWA switch cannot be implemented
• C.Change the receiving control vlan of SWB switch and SWC switch to 10, SWB switch and SWC switch refresh MAC and ARP through traffic
• D.Change the receiving control VLAN of SWB switch and SWC switch to 10, then the SmartLink backup function of SWA switch can be implemented normally

After executing the display interface Ethernet 1/0/2 command on the switch SWA, the output information is as follows:
[SWA]display interface Ethernet 1/0/2
Ethernet1/0/2 current state: UP
PVID: 10
Mdi type: auto
Link delay is 0(sec)
Port link-type: trunk
VLAN passing: 1 (default vlan), 10
VLAN permitted: 1 (default vlan), 2-4094
Trunk port encapsulation: IEEE 802.1q
Port priority: 0
It can be judged from the above output

• A.The only VLANs existing on the switch are VLAN1 and VLAN10
• B.Data frames with VLAN20 tags will be discarded when they enter port Ethernet1/0/2
• C.Data frames with VLAN1 tags will not be stripped off when they leave port Ethernet1/0/2
• D.Port Ethernet1/0/2 only allows data from VLAN 1 and VLAN 10 to pass through

Which of the following descriptions about remote port mirroring are correct?

• A.The ProbeVLAN of remote port mirroring should prohibit MAC address learning
• B.The reflection port of remote port mirroring is essential
• C.Remote port mirroring must include the mirror source and destination switch
