Which of the following statements about backup technology is correct? (Multiple choice)
A) After deploying dual-link cold backup, when the active AC fails, the AP only needs to wait for a period of time before switching to the standby AC, which will not affect the STA business
B) After N+1 backup is deployed, when the active AC fails, the AP needs to go online to the standby AC again, and the STA will interrupt the service
C) After deploying dual-link hot backup, when the active AC fails, the AP can quickly switch to the standby AC, and the STA does not need to disconnect and reconnect
D) After deploying VRP hot backup, when the active AC fails, STA can forward data directly through the standby AC
