You want to test a new dial plan before you deploy the plan in a UCM environment.
Which of the following tools should you use? (Select the best answer.)

A.
CAR

B.
DNA

C.
RIS

D.
RTMT

Explanation:
You should use the Cisco Unified Communications Manager (UCM) Dialed Number Analyzer (DNA) to test a
new dial plan before you deploy the plan in a UCM environment. You can also use DNA to test a dial plan after
deployment. 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.
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 onnetwork. Onnetwork calls are calls routed over a single network, such as an IP data network. By
contrast, offnetwork 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 offnetwork calls.
You should not use Cisco Unified RealTime Monitoring Tool (RTMT). RTMT is a clientside application that
enables an administrator to monitor devices on a Cisco VoIP network in real time by using Secure Hypertext
Transfer Protocol (HTTPS). RTMT uses HTTPS to connect to VoIP devices and gather information, such as
device status and performance statistics, in real time. The data that is gathered by RTMT can then be used to
pinpoint problems on the VoIP network or to monitor performance thresholds.
You should not use the Cisco Realtime Information Server (RIS). The 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
UCMregistered devices are not showing up in the UCM Administration pages, you should try restarting the
Cisco RIS Data Collector service.
You should not use the Cisco Call Detail Records (CDR) Reporting and Analysis (CAR) tool. CAR is used to
generate CDR reports, Quality of Service (QoS) reports, traffic reports, and billing reports.
