You need to analyze costs across multiple GCP projects. Which tool provides detailed billing and cost analysis?

Correct answer: Cloud Billing

Option B is correct because Cloud Billing in GCP provides detailed cost and usage data across all projects within a billing account, offering features like billing exports to BigQuery, cost breakdowns by project, service, SKU, and label, as well as budget alerts and reports specifically designed for financial analysis. Option A is incorrect because Cloud Monitoring is focused on operational metrics such as CPU usage, error rates, and latency for infrastructure and application performance, not financial cost tracking across projects. Option C is incorrect because Cloud Logging collects and stores log entries from GCP services and applications for operational troubleshooting and audit purposes, and does not provide cost analysis or billing breakdowns. Option D is incorrect because Cloud Trace is a distributed tracing service used to analyze latency in application requests and is unrelated to billing or financial cost management.
