Which of the following reports can be displayed by using the CAR Device Reports menu?

A.
the current number of billing errors

B.
the call volume for a given period of time

C.
malicious call details

D.
QoS rating information for inbound calls

E.
Route and Line Group Utilization information

F.
the top number of users by maximum length of calls

Explanation:
You can display Route and Line Group Utilization information by using the Call Detail Records (CDR) Analysis
and Reporting (CAR) Device Reports menu. CAR is a reporting system that can be used to examine a variety
of statistics about a Cisco Unified Communications system, including system load and performance.
The Route and Line Group Utilization report can be accessed by clicking Device Reports > Route Patterns/
Hunt Pilots in the Cisco Unified Communications Manager (UCM) CAR graphical user interface (GUI). This
report enables a CAR administrator to view Route and Line Group Utilization as a percentage; the report can
also be used to determine whether capacity needs to be added to an existing Voice over IP (VoIP)
implementation.
You cannot display information about the current number of billing errors by using the CAR Device Reports
menu. You can view information about the current number of billing errors by using the System Reports > CDR
Error report in the UCM CAR GUI. This report enables a CAR administrator to view the number of errors that
occurred when CDR data was loaded into the reporting system.
You cannot display information about call volume for a given period of time by using the CAR Device Reports
menu. You can view information about call volume for a given period of time by using the System Reports >
Traffic > Summary by Phone Number report in the UCM CAR GUI. This report enables a CAR administrator to
choose a range of time and IP phone extension numbers from which to view call volume information, thereby
enabling an administrator to view what extensions were in use at a specific time.
You cannot display malicious call details by using the CAR Device Reports menu. You can view malicious call
details by using the System Reports > Malicious Call Details report in the UCM CAR GUI. This report enables a
CAR administrator to view call information that is tracked by the UCM Malicious Call Identification (MCID)
service. An administrator can choose to view MCID information over a period of time.
You cannot display Quality of Service (QoS) rating information for inbound calls by using the CAR Device
Reports menu. You can view QoS information for inbound calls by using the System Reports > QoS > Detail
report in the UCM CAR GUI. The Detail report enables a CAR administrator to choose a UCM network and a
period of time for which to view QoS ratings for both inbound and outbound calls. The Detail report can be used
to monitor QoS at a user level.
You cannot display information about the top number of users by maximum length of calls by using the CAR
Device Reports menu. You can view information about the top number of users by maximum length of calls by
using the User Reports menu. The By Duration report can be accessed by clicking User Reports > Top N in the
UCM CAR GUI. This report enables a CAR administrator to view users who have made the longest calls over a
given period of time, starting with the user who placed the longest call.
