Know these cold
- Documentation types: network diagrams (logical=IP/VLANs, physical=cable runs), runbooks (step-by-step procedures), knowledge base articles (solved problems for reuse).
- Professionalism: active listening, clear communication, managing user expectations, respecting privacy, and maintaining confidentiality.
- Backup: 3-2-1 rule (3 copies, 2 media types, 1 offsite). Test restores regularly — a backup never tested is not a backup.
Meerk's quiz — open the Lesson 20 gate
10 questions, no time limit. 85% on your first attempt in a 24-hour window opens the gate. Retakes inside the window are practice — they help you learn, they don't count. Work alone; the point is to know it, not to have seen it.
Dinner Table Question
Ask at home: Why is documenting your fixes as important as making the fix itself?
En español: ¿Por qué documentar tus soluciones es tan importante como hacer la corrección misma?
