Answer: A Monitoring Workspace

## Explanation **Correct Answer: B) A Monitoring Workspace** **Why this is correct:** 1. **Monitoring Workspace Purpose**: Google Cloud Monitoring Workspace is specifically designed to aggregate monitoring data from multiple GCP projects into a single dashboard view. 2. **Multi-Project Monitoring**: A Monitoring Workspace allows you to monitor resources across different GCP projects from a centralized location, which is exactly what the question requires. 3. **Dashboard Consolidation**: With a Monitoring Workspace, you can create dashboards that display metrics and logs from multiple projects, eliminating the need for separate dashboards for each project. **Why other options are incorrect:** - **A) Separate dashboards**: This would require maintaining multiple dashboards, which contradicts the requirement for a "single monitoring dashboard." - **C) Pub/Sub**: Pub/Sub is a messaging service for event-driven systems and streaming analytics, not for creating monitoring dashboards. - **D) Cloud Router**: Cloud Router is a fully distributed and managed Google Cloud service that lets you dynamically exchange routes between your Virtual Private Cloud (VPC) network and your on-premises network using Border Gateway Protocol (BGP). It has nothing to do with monitoring dashboards. **Key Takeaway**: When you need to monitor multiple GCP projects from a single dashboard, you should use a Monitoring Workspace, which provides centralized monitoring capabilities across projects.
