I’m a bit confused about option C; I thought the remote instance could only take over if the primary instance was completely down, but I’m not sure.

I think option B sounds familiar because we discussed how DTS helps with real-time data synchronization in our practice sessions.

I remember something about needing an Alibaba Cloud Intranet address for the primary database, but I'm not entirely sure if that's a strict requirement.
