You need to ensure that you receive compliance information for the configuration baseline from all of the computers

Your company has 2,000 desktop computers and 450 portable computers. The desktop computers
run Windows 7 Enterprise (x64) and the portable computers run Windows 7 Professional (x86). The
network contains a System Center 2012 Configuration Manager environment. You create a
configuration baseline that is targeted to all of the computers.
You discover that you fail to receive compliance information for the configuration baseline from the
portable computers.
You receive compliance information for the configuration baseline from the desktop computers.
You receive compliance information for other configuration baselines from all of the computers.
You need to ensure that you receive compliance information for the configuration baseline from all
of the computers.
What should you do?

A.
Configure the configuration item to be evaluated on all Windows 7 operating systems.

B.
Create custom client settings for the portable computers and enable Compliance Settings.

C.
Create a collection containing the portable computers and assign the configuration baseline to the
collection.

D.
Add the configuration item to a new configuration baseline.

Introduction to Compliance Settings in Configuration Manager
Compliance settings in System Center 2012 Configuration Manager provides a unified interface and
user experience that lets you manage the configuration and compliance of servers, laptops, desktop
computers, and mobile devices in your organization. Compliance settings contains tools to help you
assess the compliance of users and client devices for many configurations, such as whether the
correct Windows operating system versions are installed and configured appropriately, whether all
required applications are installed and configured correctly, whether optional applications are
configured appropriately, and whether prohibited applications are installed. Additionally, you can
check for compliance with software updates, security settings, and mobile devices. Configuration
item settings of the type Windows Management Instrumentation (WMI), registry, script, and all
mobile device settings in Configuration Manager let you automatically remediate noncompliant
settings when they are found.
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. You can import this configuration data from the web in Microsoft System Center Configuration
Manager Configuration Packs as best practices that are defined by Microsoft and other vendors, in
Configuration Manager, and that you then import into Configuration Manager. Or, an administrative
user can create new configuration items and configuration baselines.

How to Deploy Configuration Baselines in Configuration Manager
Configuration baselines in System Center 2012 Configuration Manager must be deployed to one or
more collections of users or devices before client devices in those collections can assess their
compliance with the configuration baseline.
Question says: this and only this new baseline isn’t working on portable devices.
Reason: Maybe this baseline wasn’t deployed to those PCs.
The client/agent on all computers seems to be OK.
What is it?
-A Configuration Manager client downloads its client policy on a schedule that you configure as a
client setting. However, there might be occasions when you want to initiate ad-hoc policy retrieval
from the client— for example, in a troubleshooting scenario or when you are testing.
Use the following procedures to initiate ad-hoc policy retrieval from the client outside its scheduled
polling interval, either by using the Actions tab on the Configuration Manager client or by running a
script on the computer. You must be logged on to the client computer with local administrative
rights to perform these procedures.
-The reporting services aren’t correctly configured

But: Configure the configuration item to be evaluated on all Windows 7 operating systems Indicates
that this wasn’t the case.
