LPIC-2 Advanced Networking Configuration Practice Question
Which TWO of the following tools are used to capture and analyze network packets on a Linux system?
⚠ Common exam trap
It's easy for candidates to confuse tools that manipulate packets (like iptables) or scan networks (like nmap) with tools that passively capture and decode packet contents, leading them to select iptables or nmap instead of recognizing that only tcpdump and tshark perform raw packet capture and analysis.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
tcpdump
tcpdump is a command-line packet analyzer that captures raw network packets from the wire by placing the network interface into promiscuous mode and using libpcap to read packets. It allows filtering based on protocols, ports, and hosts using BPF (Berkeley Packet Filter) syntax, making it a fundamental tool for network troubleshooting and security analysis.
