Reply To: Review Mode Set 4 – overall quality of the questions is low

[D Alfano]

For future reference of those who may see this while using AI to scrutinize this question, yes, it has yet to be revised and yes AI is hallucinating into thinking its fine.

The spirit of the answer is correct but the stem is objectively poorly written.
As mentioned, it begins with a singular instance, but even if you consider the mention of Reserved instances only as an elected billing option, it still goes on to use “web servers” plural.

The idea is that by using a mix of on-demand and spot instances, you are taking advantage of the reserved instance billing option as your steady-state and scaling with cheap spot instances as needed while load balancing.
