I’m not sure about C. A single machine sounds risky for data.

I practiced a similar question about data persistence, and I think D is likely true since redundancy is important for log data.

I'm not entirely sure about the architecture details, but I feel like LVS + NGINX sounds familiar for load balancing.

I remember Logtail being mentioned as a non-intrusive log collector, so I think A is correct.
