You need to ensure that mobile device information is available in the hardware inventory

Your network contains a System Center 2012 Configuration Manager environment as shown in the
exhibit. (Click the Exhibit button.)

(The exhibit shows that: Server5 and Server6 are in the perimeter network, while Server1, Server2,
Server3, and Server4 are in the internal network.)
The network contains six servers. The servers are configured as shown in the following table.

You need to ensure that mobile device information is available in the hardware inventory.
What should you do first?

A.
Install a management point on Server5.

B.
Configure IIS to support only HTTPS on Server5.

C.
Install a management point on Server2.

D.
Install Network Load Balancing (NLB) on Server3.

E.
Install an enrollment proxy point on Server6.

F.
Configure IIS to support only HTTP on Server3.

G.
Install a software update point on Server3.

H.
Install Network Load Balancing (NLB) on Server6.

I.
Install a PXE-enabled protected distribution point on Server5.

J.
Install the Windows Cluster service on Server3.
K.
Install a PXE-enabled protected distribution point on Server4.
L.
Install the Windows Cluster service on Server6.
M.
Install Windows Server Update Services (WSUS) on Server3.
N.
Install a protected distribution point on Server1.

Explanation:
This is almost a discussion about which came first: the chicken or the egg.
At first glance, I would have said that the correct answer is “Configure the Exchange connector on
Server3″.
However, that answer is not available in this question, leaving only the “Enrollment Proxy Point” as a
possible answer.

How to Install Clients on Mobile Devices and Enroll Them by Using Configuration Manager

When you enroll mobile devices by using System Center 2012 Configuration Manager, this action
installs the
System Center 2012 Configuration Manager client to provide management capabilities that include
hardware inventory, software deployment for required applications, settings, and remote wipe.
To enroll these mobile devices, you must use Microsoft Certificate Services with an enterprise
certification authority (CA) and the Configuration Manager enrollment point and enrollment proxy
point site system roles. During and after enrollment, public key infrastructure (PKI) certificates
secure the communication between the mobile device and the Configuration Manager site. When
the certificate on the mobile device is due for renewal, users are automatically prompted to renew
their certificate. When they confirm the prompt, Configuration Manager automatically re-enrolls
their mobile device.
..
Use the following steps and the supplemental procedures to install the client and enroll mobile
devices in Configuration Manager. After you complete these steps, you can monitor the mobile
devices that are enrolled by viewing the collections that display mobile devices, and by using the
reports for mobile devices:

Determine How to Manage Mobile Devices in Configuration Manager
Use the following information to help you decide how to manage mobile devices in System Center
2012 Configuration Manager. You can use Configuration Manager to enroll mobile devices and install
the Configuration Manager client, you can use the mobile device legacy client (for example, for
Windows CE mobile operating systems), and you can use the Exchange Server connector. In addition,
in Configuration Manager SP1, you can enroll devices that run Windows Phone 8, Windows RT, and
iOS by using the Windows Intune connector.
The following table lists these four mobile device management methods and provides information
about the management functions that each method supports:
