Wireshark D5 V7 - HTTP analysisTroubleshoot your network

The video tutorial covers network scalability and planning, emphasizing the importance of baselining to detect abnormal network behavior. It introduces Wireshark as a tool for identifying network issues, focusing on using the expert system and analyzing latency. Techniques for detecting malicious traffic are discussed, including examining protocol hierarchies and identifying unrecognized ports. The tutorial also highlights common causes of network congestion, such as high usage of voice over IP and streaming protocols, and the impact of broadcast traffic.

What is the primary purpose of using a baseline in network management?

• To increase network speed

• To detect abnormal network behavior

• To enhance network security

• To reduce network costs

Which feature in Wireshark helps in identifying errors and warnings in network traffic?

• IO Graphs

• Protocol Hierarchy

• Time Display Format

• Expert System

How can you measure the time difference between packets in Wireshark?

• By using the protocol hierarchy

• By selecting 'seconds since previous captured packet'

• By analyzing the TCP errors

• By checking the expert system

What is a common indicator of malicious traffic in Wireshark?

• Frequent DHCP requests

• High latency between packets

• Unrecognized ports in TCP conversations

• Low bandwidth usage

Which protocol's misconfiguration can lead to increased network traffic due to multicast?
