Quiz — Networking Commands
Quiz on ip, ping, traceroute, wget, curl, and ssh
Module 4 Knowledge Check — apply networking commands
You inventoried interfaces, treated ping as ICMP not omniscience, read ss listeners, and handled curl/SSH without leaking secrets. Ten APPLY scenarios. Scope is still your machine unless a question says you are authorized. Next module: Pipes and Redirection (|, >, >>).
APPLY: A ticket says "give me the VM IP." ip -br addr lists lo 127.0.0.1/8 and eth0 192.168.56.10/24. What do you send?
APPLY: ping 8.8.8.8 fails from a hardened laptop, but curl -I https://example.com succeeds. Best conclusion?
APPLY: ss -tuln shows 127.0.0.1:8080 and 0.0.0.0:22. You are about to join public Wi-Fi. Which bind is the bigger LAN exposure?
APPLY: You want HTTP status and headers from a site you own, not the HTML body. Which command matches the job?
APPLY: First SSH to your new cloud VM asks to trust a fingerprint. Secure habit?
APPLY: ifconfig is missing; ip addr shows inet 10.0.0.5/24 on ens33. What does /24 tell you?
APPLY: True or False: traceroute * * * at one hop always means the entire path is dead and you should stop using HTTPS.
APPLY: Which two actions stay inside ethical self-recon? (Select 2)
APPLY: A teammate wants to "just copy" ~/.ssh/id_ed25519 into Slack so they can finish a deploy. What do you do?
APPLY: True or False: After this module, the next Linux Fundamentals skill drop is chaining commands with pipes and redirection (|, >, >>) so you can save and search command output.
