 In Wireshark, to filter traffic for a specific LAN, the correct syntax uses ip.src== and ip.dst== to specify the source and destination IP addresses. The /16 denotes the subnet mask, indicating that we are interested in the entire 10.11.x.x range. This filter will show all traffic where both the source and destination IP addresses fall within the specified LAN, excluding any internet traffic. References: The information is based on the Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) course, which covers network intrusion analysis and the use of tools like Wireshark for traffic analysis1.

HTTPS uses SSL/TLS encryption to secure data transmission over the internet. This encryption makes it difficult to monitor HTTPS traffic because the data packets are encrypted making them unreadable to anyone trying to intercept or monitor the data without proper decryption keys. References := Cisco CyberOps Associate

Full packet captures are essential for troubleshooting security and performance issues as they provide detailed information on network traffic (option B). They also allow for reassembling fragmented traffic from raw data, enabling analysts to review complete transactions or sessions (option C). References := Cisco Cybersecurity Operations Fundamentals - Module 3: Network Data and Event Analysis
