Which of the following is required to enable Stack Monitoring?

To enable Stack Monitoring:

Dynamic group for discovery service (A): A dynamic group defines resources (e.g., compute instances) that Stack Monitoring can discover and monitor. A policy granting permissions to this group is also required.

Why not B or C?

Machine Learning group (B): Not a valid OCI concept for Stack Monitoring.

User group for VCN collection (C): User groups manage human access, not service discovery.

This setup ensures Stack Monitoring can access and monitor resources.
