Which three elements are used to configure calling privileges? (Choose three)

Route patterns define dialable digit strings and their routing destinations but are placed inside partitions to enforce privilege, so they are not themselves a calling privilege configuration element.

A Calling Search Space (CSS) is an ordered list of partitions assigned to a device or line that defines the complete set of route patterns and directory numbers the caller is permitted to reach.

Replica is a CUCM database replication concept related to cluster node synchronization and has no role in call routing access control or calling privileges.

While end users can be assigned a CSS, the User object itself is not one of the three core elements that constitute the calling privilege configuration framework.

A Partition is a logical grouping applied to route patterns and directory numbers that restricts access so that only callers whose CSS includes that partition can dial those numbers.

A Time Schedule is associated with a partition to limit access based on time of day, enabling time-of-day routing as a core part of calling privilege enforcement.
