What tool is often used for monitoring the integrity of communications in a network?

The choice indicating all of the above as a tool for monitoring the integrity of communications in a network reflects the understanding that various tools can play a role in this process. Each of the options listed, including trace route, packet sniffer, and network analyzer, contributes to maintaining and assessing the integrity of network communications through different functionalities.

Trace route is used to determine the path that packets take to reach their destination, which can help identify where communication issues are occurring. By monitoring the route, network administrators can detect disruptions or delays that might indicate integrity problems.

Packet sniffers capture and analyze the packets of data traveling across the network. By inspecting these packets, they can identify unauthorized changes, data breaches, or other irregularities that would compromise the integrity of the communication.

Network analyzers combine various capabilities to monitor, analyze, and report on network traffic in real time. They can assess performance issues and security threats, ensuring that the communications remain intact and secure.

Each of these tools plays a distinct role in monitoring network communications, making it correct to conclude that all of them can contribute to the integrity monitoring effort.
