Answer: Generate alerts for costs that exceed defined thresholds., Estimate the cost of a planned workload.

AWS Billing and Cost Management provides tools for: 1. **Cost estimation** - AWS Pricing Calculator allows companies to estimate the cost of planned workloads before deploying them 2. **Cost monitoring and alerts** - AWS Budgets enables setting custom cost thresholds and generating alerts when costs exceed defined limits **Why other options are incorrect:** - **Manage access to AWS services and resources**: This is handled by AWS Identity and Access Management (IAM), not Billing and Cost Management - **Estimate the costs of migrating data centers to the cloud**: While AWS does offer migration cost estimation tools, this is typically part of AWS Migration Evaluator or AWS Migration Hub, not the core Billing and Cost Management service - **Conduct AWS Well-Architected Framework reviews**: This is performed through AWS Well-Architected Tool, which is separate from billing and cost management services **Key AWS Billing and Cost Management features include:** - AWS Cost Explorer for analyzing costs - AWS Budgets for setting cost and usage budgets - AWS Pricing Calculator for estimating costs - Cost allocation tags for tracking costs by department, project, etc.
