Wait, are logs really saved in triplicate? That seems excessive!

LVS + NGINX? Sounds right, but I need to double-check that.

I think D is definitely right; saving logs in triplicate sounds familiar from our study materials.

I have a vague memory that Logstore data isn't just on one machine, so C seems off to me.

I'm not entirely sure about the architecture details, but I feel like I saw something about LVS and NGINX in a practice question.

This seems like a tricky one. The details about the backend service and data replication are not something I'm fully confident on. I'll have to make an educated guess on this.

Hmm, I'm a bit unsure about the architecture details of Alibaba Cloud Log Service. I'll need to review my notes on the system design to answer this properly.

The RFQ process can be tricky, but I've got a strategy - I'll eliminate the options that don't sound right, then choose the two that seem most accurate.

I think I know the answer to this one. Property values are inherited from the closest ancestor, except when a specific value has been entered. That's definitely one of the true statements.

I think a practice question mentioned something about improving payment practices. It could be important to pay suppliers on time to build trust.

Ah, I see. The Logtail agent, the LVS + NGINX architecture, and the triplicate data storage all make sense. But I'm a bit surprised the Logstore backend isn't more distributed for scalability.

Haha, a single machine for the Logstore backend? That's bold, I wonder if it can handle the real-time processing demands. Although, I guess Alibaba knows what they're doing.

I'm not too familiar with the Alibaba Cloud Log Service, but the triplicate data storage sounds like a great way to ensure reliability. And the Logstore backend being on a single machine seems a bit risky to me.

A, B, and D seem to be the correct options here. Logtail is pretty neat, and the LVS + NGINX architecture is a classic for high-performance web services.
