Network Defense Essentials (NDE) Practice Exam

What method is used by network specialists to filter and capture specific types of traffic in Wireshark?

1. Protocol Analysis

2. Traffic Filtering

3. Data Analytics

4. Network Monitoring

The correct answer is: Traffic Filtering

The method network specialists use to filter and capture specific types of traffic in Wireshark is known as Traffic Filtering. This approach allows users to specify criteria that determine which packets are displayed in the Wireshark interface. By applying filters using protocols, IP addresses, port numbers, or other attributes, users can isolate the traffic that is relevant to their analysis, making it easier to troubleshoot network issues or investigate suspicious activity. Traffic filtering is essential because Wireshark can capture a vast amount of data in real-time, and without filtering, it would be challenging to identify the specific packets of interest. In contrast, the other methods mentioned do not specifically address the targeted capture of packets. Protocol Analysis involves studying the behavior and specifications of communication protocols, which is broader than just filtering. Data Analytics typically refers to the examination of data sets to find patterns or insights rather than the direct manipulation of captured network traffic. Network Monitoring is a general term that encompasses various tools and techniques for observing network activity but does not necessarily involve the specific filtering capabilities that Wireshark provides.
