Introduction to Collections in Configuration Manager
Collections in System Center 2012 Configuration Manager represent logical groupings of resources,
such as users and devices. You can use collections to help you perform many tasks, such as managing
applications, deploying compliance settings, or installing software updates. You can also use
collections to manage groups of client settings.
..
Query Rule
Query rules dynamically update the membership of a collection based on a query that Configuration
Manager runs on a schedule. For example, you can create a collection of users who are a member of
the Human Resources organizational unit in Active Directory Domain Services. Unlike direct rule
collections, this collection membership automatically updates when you add or remove new users to
the Human Resources organizational unit.

Planning for Client Settings in Configuration Manager
Use client settings in System Center 2012 Configuration Manager to configure user and device
settings for the hierarchy. Client settings include configuration options such as the hardware
inventory and schedule, and the polling schedule for client policy.

All Configuration Manager clients in the hierarchy use the Default Client Settings that are
automatically created when you install Configuration Manager. However, you can modify the default
client settings and you can create custom client settings to override the default client settings for
specific users or devices.

Introduction to Compliance Settings in Configuration Manager

Compliance is evaluated by defining a configuration baseline that contains the configuration items
that you want to evaluate and settings and rules that describe the level of compliance you must
have.
