What is the primary function of Wireshark in network management?

Wireshark serves as a powerful network protocol analyzer, primarily functioning to capture data packets traveling through a network connection. By collecting and displaying these packets, Wireshark allows network administrators and cybersecurity professionals to analyze network traffic in real time. This functionality is crucial for identifying issues such as bottlenecks, unauthorized usage, or potential security threats within the network.

Additionally, Wireshark provides detailed insights into the different protocols used in communication, which can help in diagnosing network problems or understanding traffic patterns. This enhances its utility in both network management and cybersecurity efforts, enabling comprehensive monitoring and analysis of the overall health and security of the network environment.

The other options pertain to unrelated functions that do not align with Wireshark's capabilities. For example, while encryption and access blocking are essential for securing a network, they are not purposes served by Wireshark itself. The tool focuses exclusively on traffic analysis rather than enforcing security measures like firewalls or encryption protocols.
