Which of the following best describes the purpose of the UCM DNA?

A.
It records outbound dialed numbers for later review in RTMT.

B.
It analyzes dialed numbers to determine how the call should be billed.

C.
It is used to test dial plans both before and after deployment.

D.
It maintains real-time device registration status information.

Explanation:
The Cisco Unified Communications Manager (UCM) Dialed Number Analyzer (DNA) is used to test dial plans
both before and after deployment. A dial plan is a set of rules, or route plan, that determines how calls reach
their destinations. A Voice over IP (VoIP) dial plan enables a company to route calls between geographically
dispersed sites while keeping the calls on-network. On-network calls are calls routed over a single network,
such as an IP data network. By contrast, off-network calls are calls that are routed through multiple telephony
networks, such as those routed over the public switched telephone network (PSTN). DNA and verification of the
calling search space are both ways to troubleshoot error recordings when attempting to make off-network calls.
DNA does not record outbound dialed numbers for later review in the Cisco Unified Real-Time Monitoring Tool
(RTMT). DNA initially displays results in a new browser window. However, you can export data from DNA in the
form of an Extensible Markup Language (XML) file, not log data that is displayed by RTMT.
DNA does not maintain real-time device registration status information. The Cisco Real-time Information Server
(RIS) maintains device registration statuses, performance counter information, and information about critical
alarms in real time. Similar to DNA, the Cisco RIS Data Collector, which transmits data to the RIS, runs as a
UCM service. If you notice that UCM-registered devices are not showing up in the UCM Administration pages,
you should try restarting the Cisco RIS Data Collector service.
DNA does not analyze dialed numbers to determine how the call should be billed. Billing reports are typically
generated by the Cisco Call Detail Records (CDR) Reporting and Analysis (CAR) tool. CAR also generates
CDR reports, Quality of Service (QoS) reports, and traffic reports.
