Quiz — Network Scanning
10 APPLY questions on localhost-only scanning ethics and TCP meaning.
Opening
Network scanning — Module Quiz
Ten APPLY items on the lock this module refused to lift: HOST stays "127.0.0.1" (or, outside this homework script, a VM you truly own with writing). A scan is many connect attempts. connect_ex plus timeout is a question to YOUR listener. OPEN means the TCP handshake completed from here; closed_or_filtered / timeout means not open in the wait window — empty OPEN is valid, not a hunting license. Connect versus SYN/half-open is defender literacy (completed sessions are noisier in many logs); it is not an IDS-evasion cookbook, not nmap timing templates, not a café Wi-Fi stealth playbook. Café /24, campus library, neighbor, and internet nmap are failing answers even when a blog titled them “CEH scanning.” The lab artifact is $HOME/cyberlium-lab/ceh-scan.txt (or localhost-scan-lab-notes.txt) chmod 600, optional python -m http.server --bind then stop. This is original Cyberlium teaching mapped to a CEH v13 scanning-networks domain — not official EC-Council training, not a cert, not exam dumps. Completing these lessons does not grant CEH. Wrong answers still teach. Next after this quiz is Enumeration vs Scanning: doors versus nameplates, still on a listener YOU started, still no campus AD.
Knowledge Check
APPLY: A classmate times out on 127.0.0.1:443 and wants to nmap the café /24 and campus printers “because scanning networks is the module.” What is a scan here, and what do you do?
Multiple choice
Knowledge Check
APPLY: True or False: connect_ex with a timeout is only a question, so campus library scans are legal practice as long as you do not log in.
True or False
Knowledge Check
APPLY: A classmate wants nmap timing templates and a SYN scan of café Wi-Fi “to learn stealth.” What did connect vs stealth mean here?
Multiple choice
Knowledge Check
APPLY: Your script prints connect_ex 0 on 127.0.0.1:8000 after you started http.server. What is OPEN, and what is it not?
Multiple choice
Knowledge Check
APPLY: Select statements that match this module’s HOST lock and output reading. (Select 2)
Select all that apply
Knowledge Check
APPLY: You finished the optional http.server pass. Which cleanup and note pairing is required?
Multiple choice
Knowledge Check
APPLY: True or False: Because completed connections are more visible in logs, you should always half-open scan the dorm so application logs miss you.
True or False
Knowledge Check
APPLY: Why does the lab Python refuse any HOST other than 127.0.0.1, and where do notes live?
Multiple choice
Knowledge Check
APPLY: A blog titled with a cert acronym publishes “scanning commands” aimed at 192.168.1.0/24 including timing templates to evade IDS. What does Cyberlium Module 3 tell you?
Multiple choice
Knowledge Check
APPLY: You carry Module 3 into Module 4. Which pairing is true, and what opens after this quiz?
Multiple choice
Knowledge Check
APPLY: curl of http://192.168.0.1/ shows a home router login (TP-Link / Netgear / Huawei / "Router Admin"). Is that DEMO in scope as a hacking target?
