Which statement about application scopes in ServiceNow is true?

Application scopes in ServiceNow serve a crucial role in organizing and securing applications by isolating them from one another. The correct statement asserts that scopes separate application data for security reasons. This isolation ensures that resources (like tables, scripts, and other assets) belonging to one application cannot be inadvertently accessed or modified by another application, thereby maintaining data integrity and enhancing security.

The mechanisms provided by scopes allow developers to enforce data access controls and guidelines, which are particularly important in multi-tenant environments where numerous applications may coexist. By restricting access at the scope level, ServiceNow helps safeguard sensitive information and manage the complexities of application development.

The other statements do not accurately capture the primary function of application scopes. While user interfaces can be defined within a scope, the scope itself does not define the user interface. Scopes can be shared among different applications under specific conditions using cross-scope privileges, which contradicts the notion that they cannot be shared. Lastly, stating that all applications use the same scope would undermine the foundational concept of scopes, which is to promote separation and independence among different applications.
