Where are the master repositories for Endpoint Security System (ESS) servers held?

The master repositories for Endpoint Security System (ESS) servers are held at PRNOC and UARNOC. This is significant because these facilities are strategically chosen for their robustness and reliability to manage critical security data.

Having master repositories in these specific locations ensures that data is centralized and easily accessible for security updates, incident response, and overall system integrity. This setup also typically supports redundancy and disaster recovery measures, enhancing the resilience of the Endpoint Security System. By keeping master repositories in these facilities, organizations can ensure that their security operations are efficient and well-coordinated, allowing for timely updates and management of endpoints that are critical to the security posture of the organization.

The other options listed involve different combinations of locations that do not serve as core repositories for ESS, indicating that they may not have the necessary infrastructure or focus to support Endpoint Security in the same centralized manner.
