Your company uses System Center 2012 Configuration Manager to deploy applications. The
company purchases a new application named App1. App1 can be installed only on client
computers that run Windows 7.
You need to ensure that App1 is installed only on Windows 7 computers that have at least 2
Gb of memory and 300 Gb of free disk space.
What should you create?

A.
a Query object

B.
custom client user settings

C.
a configuration baseline

D.
a query-based collection

Explanation:
Previous experience with this question is that the answer should be “a requirement rules”.
However, since this question does not provide that possibility, the next best thing is “a querybased collection”.

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.
