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

[wat]

Hi,

Is the Review Mode Set 4 the latest set of questions?

Both the questions and answers are multi interpretabel, or incomplete.

It seems that all these questions need better reviewing. Or do you rely on the users for reviewing these questions?☹

Example 1:

“A digital media publishing company hired a solutions architect to manage its online portal, which is deployed on a single Amazon EC2 instance. The architecture uses a combination of Reserved EC2 Instances to handle the steady-state load and On-Demand EC2 Instances to handle the peak load. Currently, the web servers operate at 90% utilization during peak load.”

This questions contradicts itself(is it a single instance or a combination of reserved and ondemand?)

Hello wat,

Good day!
I can assure you that we regularly update all our questions including the Review Mode Set 4 in AWS CSAP practice exam bank of ours.
Regarding your question, you can think of Reserved and On-Demand instances as different pricing options rather than different types of instances. So, when we say the architecture uses a combination of Reserved and On-Demand EC2 Instances, we’re referring to the pricing strategy. The single EC2 instance is used consistently (taking advantage of Reserved pricing for cost savings) and also handles additional workload during peak times (which would be covered by On-Demand pricing)
For more information of the two pricing models, kindly check this link pls: https://aws.amazon.com/compare/the-difference-between-on-demand-instances-and-reserved-instances/
I do understand that this question might have been worded more clearly. With that said, we will do the necessary update for this question as soon as we can.
Thank you.

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.
