In Huawei's SD-WAN solution, for the scenario of "branch access using 4G/5G wireless links", which of the following technologies can "cope with wireless link signal fluctuations and ensure service continuity"?

• A.Using only a single wireless link, service is interrupted when the signal fluctuates.
• B.Automatic reconnection of the wireless link is disabled and requires manual intervention to restore.
• C.SD-WAN wireless link optimization technology (enables link stabilization and automatically switches to backup links)
• D.Reduce the wireless link transmission rate to minimize the impact of signal fluctuations.
