DRAG DROP
You need to collect the required security logs.
Which three actions should you perform in sequence? To answer, move the appropriate actions
from the list of actions to the answer area and arrange them in the correct order.
Answer: See the explanation
Explanation:
Box 1: Install and configure Audit Collection Services on DETSCOM01.
Box 2: Modify the properties of the Operations Manager agent on DETCA01 and CHICA01 to enable
an Audit Collection Services forwarding server.Box 3: In the Agent Health State section of the Operations Manager console, select DETCA01 and
CHICA01 and enable audit collection.
Note:
* Audit collection services (Box 1)
In System Center 2012 – Operations Manager, Audit Collection Services (ACS) provides a means to
collect records generated by an audit policy and store them in a centralized database.
ACS requires the following components: ACS Forwarders, ACS Collector, ACS Database
* ACS Forwarders (box 2)
The service that runs on ACS forwarders is included in the Operations Manager agent. By default,
this service is installed but not enabled when the Operations Manager agent is installed. You can
enable this service for multiple agent computers at the same time using the Enable Audit Collection
task.
* (box 3) Enable audit collection
. After you install the ACS collector and database you can then remotely enable this service on
multiple agents through the Operations Manager console by running the Enable Audit Collection
task.
To enable audit collection on Operations Manager agents (see step 5 below)
Log on to the computer with an account that is a member of the Operations Manager Administrators
role. This account must also have the rights of a local administrator on each agent computer that
you want to enable as an ACS forwarder.
In the Operations console, click Monitoring.
In the navigation pane, expand Operations Manager, expand Agent Details, and then click Agent
Health State. This view has two panes, and the actions in this procedure are performed in the right
pane.
In the details pane, click all agents that you want to enable as ACS forwarders. You can make
multiple selections by pressing CTRL or SHIFT.
In the Actions pane, under Health Service Tasks, click Enable Audit Collection to open the Run Task
– Enable Audit Collection dialog box.

Copied from comment in Question 48.
Overview
Contoso, Ltd., is a manufacturing company that makes several different components that are used in
automobile production. Contoso has a main office in Detroit, a distribution center in Chicago, and branch
offices in Dallas, Atlanta, and San Diego. The contoso.com forest and domain functional level are Windows
Server 2008 R2. All servers run Windows Server 2012 R2, and all client workstations run Windows 7 or
Windows 8. Contoso uses System Center 2012 Operations Manager and Audit Collection Services (ACS)
to monitor the environment. There is no certification authority (CA) in the environment.
Current Environment
The contoso.com domain contains the servers as shown in the following table:
Contoso sales staff travel within the United States and connect to a VPN by using mobile devices to
access the corporate network. Sales users authenticate to the VPN by using their Active Directory
usernames and passwords. The VPN solution also supports certification-based authentication.
Contoso uses an inventory system that requires manually counting products and entering that count into a
database. Contoso purchases new inventory software that supports wireless handheld scanners and
several wireless handheld scanners. The wireless handheld scanners run a third party operating system
that supports the Network Device Enrollment Service (NDES).
Business Requirements
Security
The wireless handheld scanners must use certification-based authentication to access the wireless
network.
Sales users who use mobile devices must use certification-based authentication to access the VPN. When
sales users leave the company, Contoso administrators must be able to disable their VPN access by
revoking their certificates.
Monitoring
All servers must be monitored by using System Center 2012 Operating Manager. In addition to monitoring
the Windows operating system, you must collect security logs from the CA servers by using ACS, and
monitor the services that run on the CA and Certificate Revocation List (CRL) servers, such as certification
authority and web services.
Technical Requirements
CA Hierarchy
Contoso requires a two-tier CA hierarchy. The CA hierarchy must include a stand-alone offline root and
two Active Directory-integrated issuing CAs: one for issuing certificates to domain-joined devices, and one
for issuing certificates to non-domain-joined devices by using the NDES. CRLs must be published to two
web servers: one in Detroit and one in Chicago.
Contoso has servers that run Windows Server 2012 R2 to use for the CA hierarchy. The servers are
described in the following table:
The IT security department must have the necessary permissions to manage the CA and CRL servers. A
domain group named Corp-IT Security must be used for this purpose.
The IT security department users are not domain admins.
Fault Tolerance
The servers that host the CRL must be part of a Windows Network Load Balancing (NLB) cluster. The CRL
must be available to users in all locations by using the hostname crl.contoso.com, even if one of the
underlying web servers is offline.

Based on the info from Microsoft I think the correct answer should be
1) Install and configure Audit Collection Services on DETSCOM01
2) Modify the properties of the Operations Manager Agent on DETCA01 and CHICA01 to enable Audit Collection Services forwarding server
3) In the Operations Manager Console, run the task to enable audit collection on DETCA01 and CHICA01 and verify that the task completes successfully

Overview
“Contoso uses System Center 2012 Operations Manager and Audit Collection Services (ACS) to monitor the environment.”
so there is no need to install and configure ACS, you should add new server to monitor
0
0
1. install and config ACS on DETSCOM01
2. in the agent health state section…
3. In the Operations Manager Console, run the task to enable audit collection on DETCA01 and CHICA01 and verify that the task completes successfully
I don’t think you need to change the properties to enable a ACS forwarding server
