Answer Description

A protocol analyzer, also known as a packet sniffer, captures and analyzes network traffic. Understanding this primary function helps troubleshooters identify the source of network issues by examining individual packets and their contents, which could indicate problems such as traffic bottlenecks, unauthorized access, or malformed packets. The other options, while related to network maintenance or configuration, do not describe the direct functions of a protocol analyzer which is specifically designed for capturing and analyzing network traffic.
