Hmm, I wonder if they'll ask about the best way to handle traffic spikes - a trampoline or a catapult?

Option B? Really? That's just ridiculous. Who cares about the OS as long as the servers can handle the traffic?

D seems like the logical choice to me. For the SLB to work seamlessly with Auto Scaling, the backend servers should have the same configuration.

I think C is the right answer. The Auto Scaling feature works best when all the backend servers are in the same scaling group.

Option A sounds reasonable, but I'm not sure if it's the only correct one. The health check is important, but there may be other requirements as well.

I'm not sure about option C. Do all backend servers really need to be in the same Scaling Group?

I agree with Veronica. Having Health Check enabled ensures the system is stable.

I think option A is correct because Health Check is important for SLB instances.
