A is definitely the way to go for load balancing!

Wait, how can D be true? That sounds odd.

C doesn't make sense. The other instance should still get requests.

I disagree with B. Multiple instances can be deployed.

Option D sounds confusing to me. I thought each request would go to one instance, not both, but I can't remember the exact details from our study sessions.

I recall a similar question where we talked about instances on different nodes. I think option C is misleading because it suggests that the instance on a different node can't receive requests at all.

I'm not entirely sure, but I feel like option B seems too restrictive. I think we can deploy multiple instances based on what we practiced.

I remember discussing how load balancing works, so I think option A might be correct since it mentions handling requests by different instances.

Hmm, I'm a bit unsure about this one. The options seem pretty similar, so I'll need to really focus and think it through. Maybe I'll start by eliminating the options I'm more confident aren't the exception.

I'm pretty confident the Azure container networking plugin is the right choice. It sounds like it gives each pod a unique IP address that can be directly accessed, which is exactly what we need for this use case.
