Which purpose of the Dialed Number Analyzer within Cisco Unified Communications Manager is true?
The correct answer is B. It is used as a troubleshooting tool as it provides an efficient way to analyze the dial plan. The Dialed Number Analyzer (DNA) in CUCM is a dial plan troubleshooting tool that simulates call routing without placing a real call.

Why each option
The Dialed Number Analyzer (DNA) in CUCM is a dial plan troubleshooting tool that simulates call routing without placing a real call.
DNA does not query CDR logs; retrieving called-number data from call records is a function of the CDR Analysis and Reporting (CAR) tool.
DNA allows an administrator to enter a device and a dialed string, then traces which calling search spaces, partitions, route patterns, and translation patterns would be applied, making it an efficient tool for validating or debugging dial plan logic. It performs a static simulation rather than processing a live call, so it is safe to use in production without impacting traffic.
DNA is a pre-call simulation tool and does not monitor or display DNIS data during live, in-progress calls.
Sorting and analyzing CDR logs is handled by the CAR tool in CUCM, not by the Dialed Number Analyzer.
