Data encryption? That seems a bit off for a proxy.

Failover strategies for high availability seems like something they would include, but I'm a bit uncertain about data encryption being part of the proxy features.

Health checks for nodes sounds familiar, but I can't recall if it's specifically mentioned in the context of PolarDB-O.

I remember practicing a question about load balancing in PolarDB-O, so I think that one is correct too.

I'm a little confused by the terminology used in this question. I'll need to review my notes on insurance industry terms to make sure I understand the differences between the options before selecting an answer.

I remember studying the service-orientation principles, and I think "Service Reusability" might be what they're looking for here. But I'm not completely sure.

I'm pretty confident about this one. The five stages are usually campaign, election, obtaining recognition, negotiating the first contract, and enforcing the contract. The financing stage is not one of the typical five.

Wait, the proxy can do all that? I'm starting to think it's the real brains behind PolarDB-O. Maybe we should just ask the proxy to take the exam for us.

Data encryption, huh? I guess the proxy is the bouncer, making sure only the authorized guests get in.
