The finance team needs project-level cost visibility in Cost Explorer. What initial setup must a SysOps administrator perform so costs can be broken down by project?

To gain project-level cost visibility in Cost Explorer, the SysOps administrator must enable cost allocation tags. These tags are key-value pairs that you define and attach to AWS resources. By applying a 'project' tag (e.g., project:alpha, project:beta) to all resources associated with a specific project, Cost Explorer can then filter and group costs based on these tags, providing the granular breakdown the finance team requires. Consolidated billing and Cost and Usage Reports provide overall billing data but don't inherently break down costs by project without tagging. AWS Budgets are for cost control and alerts, not for detailed cost analysis by project. Cost categories group costs by AWS usage dimensions (e.g., service, account), not by custom project definitions.
