CompTIA Linux+ XK0-006 (V8) Practice Question

An administrator needs to capture only HTTPS traffic for later analysis. The capture must:

  • Listen on interface eth0
  • Record only TCP traffic whose source or destination port is 443
  • Disable hostname and service-name resolution to reduce overhead
  • Store the packets in a file named capture.pcap rather than printing them to the screen

Which tcpdump command satisfies all of these requirements?

  • tcpdump -i eth0 -nn tcp port 443 -r capture.pcap

  • tcpdump -i eth0 -nn tcp port 443 -w capture.pcap

  • tcpdump -i eth0 -nn udp port 443 -w capture.pcap

  • tcpdump -i eth0 -n tcp port 443 -w capture.pcap
