Your network contains an Active Directory domain. The domain contains 10 domain controllers that run
Windows Server 2008 R2.
You need to monitor the following information on the domain controllers during the next five days:
Memory usage
Processor usage
The number of LDAP queries
What should you do?

A.
Create a User Defined Data Collector Set (DCS) that uses the Active Directory Diagnostics template.

B.
Use the System Performance Data Collector Set (DCS).

C.
Create a User Defined Data Collector Set (DCS) that uses the System Performance template.

D.
Use the Active Directory Diagnostics Data Collector Set (DCS).

Explanation:
The System Performance Data Collector Set/System Performance template does not monitor Active Directory
data (we need the number of LDAP queries). That leaves out answers
B (“Use the System Performance Data Collector Set (DCS)”)
and
C (“Create a User Defined Data Collector Set (DCS) that uses the System Performance template”).
Because the Active Directory Diagnostics Data Collector Set (DCS) runs only for 5 minutes and we need to
monitor for 5 days we have to use a User Defined Data Collector Set (DCS) that uses theActive Directory
Diagnostics template. For a User Defined Data Collector Setwe can set the monitoring duration in seconds,
minutes, hours, days or weeks.
So we have to create a User Defined Data Collector Set (DCS) that uses the Active Directory Diagnostics
template.

AD Data Collector Sets in Win2008 and beyond
The Active Directory Diagnostics data collector setruns for a default of 5 minutes. This duration period cannot
be modified for the built-in collector. However, the collection can be stopped manually by clicking the Stop
button or from the command line. If reducing or increasing the time that a data collector set runs is required,
and manually stopping the collection is not desirable, then see How to Create a User Defined Data Collection
Set.
