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 VLAN of VLAN20, after setting the IP address of each device as shown in the figure, which statement is correct (choose one or more)

• A.SWB packets enter from SWA's GigabitEthem1/0/3 port, and after exiting from GigabitEthem1/0/3 port, the VLAN Tag carried is VLAN20
• B.The PCA packet enters from the GigabitEthem1/0/1 port of SWA, and the VLAN tag after exiting from the GigabitEthem1/0/3 port is VLAN2
• C.The PCA packet comes out of the GigabitEthem1/0/port of SWA and enters the GigabitEthem1/0/4 port of SWB. The VLAN tag carried is VLAN20
• D.When SWB accesses PCA, the VLAN tag carried by GigabitEthem1/0/4 of SWB is VLAN 10

Regarding the working mode of VoiceVLAN, the correct statement is

• A.The working mode of VoiceVLAN includes automatic and manual
• B.In manual mode, you need to manually add the IP phone to the Voice VLAN
• C.In automatic mode, the system will recognize the packet sent by the IP Phone, if the match is a voice packet, the port connected to the IP Phone will be added to the Voice VLAN
• D.In manual mode, the system will not issue ACLs to the port

Regarding the comparison of the calculation convergence of RSTP and STP, the correct statement is

• A.Compared with STP, RSTP defines a fast root port switching mechanism, which can make Altmate quickly become a new root port state when there is an obstacle to the port.
• B.If STP wants to shorten the convergence time, you can only configure a smaller FORWARD Delay time, but it will affect the stability of the network
• C.Compared with STP, RSTP defines a fast switching mechanism for designated ports, which can make the designated port enter the forwarding state without waiting for twice the Forward Delay time.
• D.Compared with STP, RSTP defines the basic port fast switching mechanism, so that the port connected to the host quickly enters the forwarding state

In the network as shown in the figure, after completing the corresponding configuration on the switch SWA, when the switch SWA receives the data frame from the PCA to access the PCB, it will judge whether to check the MAC address table or the routing table according to it.

• A.Destination MAC address of the data frame
• B.Source MAC address of the data frame
• C.VLAN attributes of data frames
• D.Source MAC address of the data frame
• E.The source IP address of the data frame

The customer LAN switches SWA, SWB, and SWC form the RRPP ring main ring 1. If the switches SWB, SWC and SWD form sub-ring 2, the above information can be derived

• A.If the switch SWB is the edge node of the sub-ring, it can initiate Maior-Fault packets
• B.If the switch SWB is the edge node of the sub-ring, it can initiate Edge-Hello packets
• C.If the switch SWA is the master node of the primary ring, it can initiate a Health message
• D.If the switch SWA is the master node of the primary ring, it can initiate Link-Down packets
