A company with 40 accounts in AWS Organizations can't tell which teams drive cost growth and wants per-team visibility plus right-sizing recommendations. Which combination addresses this?
A.Monthly invoice PDFs reviewed by finance
Invoices are too coarse and too late for engineering action.
B.Cost and Usage Report + cost allocation tags per team + Compute Optimizer recommendations
Correct. Attribution (tags) + detail (CUR) + recommendations (Optimizer).
C.CloudWatch billing alarms on the payer account only
Billing alarms alert on totals — they don't attribute or recommend.
D.AWS Trusted Advisor basic checks
Trusted Advisor is advisory and less granular than CUR+Optimizer.
Why this answer
CUR gives line-item granularity; cost allocation tags (activated in the payer) attribute spend to teams; Compute Optimizer surfaces right-sizing recommendations across accounts — the complete visibility-to-action chain.
