Which situation would necessitate multiple CPM instances?

Multiple instances of the Central Password Manager (CPM) may be required when managing accounts in multiple sites or VLANs. This scenario highlights the necessity for localized management due to geographical distribution or network segmentation. Different sites or VLANs might have diverse network policies, security requirements, or administrative controls, which can complicate centralized management. Thus, deploying multiple CPM instances helps in efficiently managing and securing privileged accounts across these diverse environments, ensuring that local policies are adhered to and performance is optimized.

In this case, having multiple CPMs allows for better scalability and flexibility in handling password management tasks for various sites or VLANs, ultimately leading to improved operational efficiency and security compliance.
