The Domain Separation Center is a centralized user interface designed for administrators to perform the overall configuration and ongoing management of the domain separation architecture within a ServiceNow instance. It consolidates various tools and settings, including system properties, domain management, and configuration validation, into a single dashboard. Its primary purpose is to streamline the administration of the entire domain-separated environment, from initial setup to routine maintenance and troubleshooting.

A. This is too vague. While the center facilitates the management of activities, its core purpose is the direct configuration and administration of the domain structure itself.

C. The Domain Separation Center is intended for global administrators (e.g., users with the domainadmin role) to manage the entire instance's domain hierarchy, not for individual domain administrators to manage their own specific domains.

D. Reviewing configuration audits is a key feature available within the Domain Separation Center, but it is not its sole or overarching purpose. The center's purpose is broader, encompassing all aspects of configuration and management.

1. ServiceNow Product Documentation: The official documentation explicitly states the purpose of the tool.

Reference: ServiceNow Product Documentation, "Domain Separation Center". In the overview section, it states, "The Domain Separation Center provides a centralized interface for configuring and managing domain separation." This directly supports that its purpose is configuration and management.

2. ServiceNow Now Learning Courseware: The official Domain Separation Implementation course details the function of the Domain Separation Center.

Reference: ServiceNow Now Learning, "Domain Separation Implementation" course materials, Module: "Domain Separation Administration". The course describes the Domain Separation Center as the primary tool for administrators to set up, validate, and manage the domain separation configuration for the instance.
