Final answer:
A protocol analyzer is the correct tool to use for identifying traffic generated by a specific application on a network.
Step-by-step explanation:
To identify traffic that is being generated and sent through the network by a specific application running on a device, you should use a protocol analyzer. A protocol analyzer, also known as a network analyzer or packet sniffer, captures and displays network traffic. It allows you to see the details of the traffic, such as the protocols being used, the source and destination of the packets, and the content of the data being transmitted, which can help in identifying application-specific traffic.
