Why each option is right or wrong
A. AWS Cost Explorer
Cost Explorer is used to view and analyze cost and usage data rather than estimate proposed architecture costs.
B. AWS Trusted Advisor
Trusted Advisor provides optimization checks and recommendations, not predeployment cost estimates for planned usage.
C. AWS Pricing Calculator
AWS Pricing Calculator is the AWS tool for estimating monthly costs for proposed solutions based on expected service usage, which matches the need to compare architectures before deployment.
D. AWS Budgets
AWS Budgets tracks or alerts on spending targets rather than modeling the expected cost of different proposed designs.
