Quiz — Denial-of-Service
10 APPLY questions on availability and legal scope.
Opening
Denial-of-service — Module Quiz
Ten APPLY items on the sentences this module refused to collapse: DoS is one-source exhaustion, DDoS is many sources, the harm is availability; volume, protocol, and application are named buckets, not flood recipes; a botnet is stolen always-on IoT with defaults and missing updates, not a cluster you assemble; organizations rate-limit (HTTP 429), absorb with anycast/CDN, and ask ISP/CDN upstream — they do not assign a café stress test; the only traffic lab is HOST hardcoded 127.0.0.1, a limiter YOU wrote, a tiny polite ~20 GET loop at YOUR listener, ceh-ratelimit-lab.txt chmod 600. Cyberlium’s artifacts are $HOME/cyberlium-lab notes (dos-vs-ddos, botnet-defender, dos-resilience, ceh-ratelimit-lab) chmod 600. LOIC, hping floods, “small SYN on the café,” classmate-site stress, worm clones, Shodan of random cameras, 429-bypass gists, and pointing the client at any other IP are all failing answers even when they look “more CEH.” This path is original Cyberlium teaching mapped to the CEH v13 denial-of-service domain — not official EC-Council training, not a certification, not exam dumps. Wrong answers still teach. Empty ethics lines fail. Next after this quiz is What a Session Token Is: Module 11 talks cookies, HTTPS, and HttpOnly as defense — still no session-hijack proof-of-concept.
Knowledge Check
APPLY: A teammate pastes LOIC, names a local shop, and says “a few seconds of CEH DoS.” What is DoS vs DDoS here, and what do you do?
Multiple choice
Knowledge Check
APPLY: True or False: A small SYN flood of the café is ethical if you stop when the page slows, because Module 10 is denial of service.
True or False
Knowledge Check
APPLY: Which sentence correctly names the three exhaustion buckets without turning them into a recipe?
Multiple choice
Knowledge Check
APPLY: A classmate wants to clone a historic IoT worm and Shodan-search cameras “to understand botnets.” What is the defender view?
Multiple choice
Knowledge Check
APPLY: Select defender actions that match “what organizations actually do” when traffic is abusive. (Select 2)
Select all that apply
Knowledge Check
APPLY: You filled dos-resilience-notes.txt. Which pairing is required?
Multiple choice
Knowledge Check
APPLY: True or False: If loopback is boring, the ethical lab is to point ratelimit_client.py at a cloud IP and run hping beside it.
True or False
Knowledge Check
APPLY: You ran the Lesson 4 lab. Which completion matches ethics and hygiene?
Multiple choice
Knowledge Check
APPLY: A blog titled with a cert acronym publishes “DoS labs” as LOIC plus hping --flood plus a botnet build. What does Cyberlium Module 10 tell you?
Multiple choice
Knowledge Check
APPLY: You carry Module 10 into Module 11. 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?
