What does setting the domain scope to global allow an admin to do?

Setting the domain scope to global enables an administrator to view all component records across the entire system, including any overridden versions. This means that when an admin has global domain scope, they have a comprehensive view of all configurations and customizations, which can be crucial for troubleshooting, auditing, or managing the various components of the service provider's system.

With this broader visibility, the admin can better understand how components are functioning together and can identify issues that may arise from overrides, ensuring consistency and integrity in the system's operations. This is especially important in a multi-domain environment where components might differ between domains, affecting the overall system performance or user experience.

Other options, while they might seem relevant to an admin's capabilities, do not accurately reflect the specific benefits granted by setting the domain scope to global. For instance, the ability to change security settings or modify system properties isn't directly tied to the global domain scope but rather to the permissions assigned to an administrator role. Similarly, restricting access to domain records typically requires more granular control mechanisms, which is not a function granted solely by the global scope. Thus, option A stands out as the correct understanding of the implications of setting the domain scope to global.
