Which of the following statements about network sniffing is true?

The statement that network sniffing captures and analyzes packets on a network is accurate and highlights the fundamental function of network sniffing tools. These tools monitor data traveling across the network by intercepting packets, allowing administrators to inspect the transmitted information. This capability is crucial for troubleshooting network issues, analyzing performance, and enhancing security by identifying unauthorized access or potential vulnerabilities.

By capturing packet data, network sniffing aids in understanding traffic patterns, detecting anomalies that could indicate malicious activities, and ensuring that data flows as expected within the network. It forms an integral part of network management and security strategies, enabling better oversight and protection of networked environments.

Other options provided do not represent the core functionality of network sniffing. They suggest aspects that are unrelated to the primary purpose of sniffing, focusing on scenarios that are not applicable to the task of monitoring and analyzing network traffic.
