As shown in the picture, SWA, SWB and SWC enable STP, and the MAC address of SWB is less than the MAC address of SWA. If the topology converges and the bridge priority of SWB is set to 0, the following statements are correct.

• A.The topology will re-converge after 30 seconds by default
• B.After SWC receives the configuration BPDU sent by SWB, it will not update immediately, but will wait for the locally saved configuration BPDU to age before updating
• C.After the priority is adjusted, SWB will immediately send configuration BPDUs with itself as the root from ports E0/1 and E0/2
• D.SWA will immediately determine that port E0/1 is the root port

In the network as shown in the figure, the corresponding configuration is completed on the switch SWA, and the switch SWA and each PC have learned the corresponding ARPPCA to access the PCB and send the ICMP request message, and the switch SWA forwards this MAC address to the PCB as

• A.MAC_A
• B.MAC10
• C.0000.0000.0000
• D.MAC20

Regarding the spanning tree port overhead configuration of H3C switches, the following statements are correct:

• A.H3C switches support three port cost standards, dot1d-1998, dot11, and legacy. The port cost standards to be followed can be switched through the command stp pathcost-standard
• B.If switches of different manufacturers are interconnected, each switch should be configured to follow the same port cost standard as much as possible, otherwise it may cause the spanning tree calculation result to deviate from the original intention of the network design
• C.By default, the larger the port cost, the smaller the port bandwidth
• D.The default spanning tree port cost standard for H3C switches is legacy

In the networking model shown in the figure, if Accoing is received on RADIUsClient, the following statement may be correct.

• A.The message is sent by Host
• B.This message is a start-accounting response message
• C.The message is sent by RADIUS Server
• D.The message is a stop-accounting response message

Routers running PIM-DM will periodically send Hello messages to discover neighbors, establish and maintain neighbor relationships. The following descriptions of Hello messages are correct. __

• A.When the DR is elected, the router with the higher priority of the Hello message will become the DR
• B.When the router runs IGMPV2, the DR is elected for the shared network segment through the PIMHello message, and the DR serves as the Querier of IGMP
• C.If Hello messages have the same priority, the router with the larger interface IP address will become the DR
• D.The router sends PIM Hello in multicast mode, the destination address is 224.0.0.13
• E.All PIM routers are members of the 224.0.0.13 multicast group
