Question 150
An architecture review recommends this solution: Model expected service usage in AWS Pricing Calculator and compare results against historical billing trends. The motivating situation is: Capacity planners need a monthly cost forecast that reflects a new Region and expected usage growth before deployment. Why is this architecture appropriate for the described workload?
Explanation
Correct Answer
This principle explains why the prescribed control is appropriate for the described requirement. The matching design action is: Model expected service usage in AWS Pricing Calculator and compare results against historical billing trends. The expected supporting evidence is: Proposed architecture cost estimates can be traced to entered quantities and forecast assumptions.
Incorrect Answers
On-demand usage was left wholly uncommitted despite predictable baseline compute consumption. The stated evidence instead indicates: Previous-month charges were presented as accurate forecasts for an expanded future footprint.
On-premises DNS has no forwarding path into the VPC's Route 53 Resolver. The stated evidence instead indicates: Previous-month charges were presented as accurate forecasts for an expanded future footprint.
Teams have only aggregate bills and cannot locate the source of inefficient storage usage. The stated evidence instead indicates: Previous-month charges were presented as accurate forecasts for an expanded future footprint.
