Which security group type allows benefits partners to see and support workers in specific location hierarchies?

The correct choice is that the security group type that allows benefits partners to see and support workers in specific location hierarchies is role-based constrained. This type of security group is designed to provide access based on defined roles while also adhering to specific constraints, such as location hierarchies.

In practical terms, this means that benefits partners have access tailored to the geographic areas or organizational structures they are responsible for, allowing them to assist workers appropriately without exposing them to information or systems outside their purview. This is particularly useful in organizations with multiple locations or divisions, as it helps maintain compliance with data privacy and security protocols.

Other options, such as organization membership or user-based security groups, provide different levels of access that might not be as finely grained in relation to location hierarchies. Role-based unconstrained would offer broader access without the necessary restrictions, which could conflict with the need for controlled support based on specific hierarchies.
