# Reflection: Five Commands, Five Answers, One Diagnosis

## Reflection questions

1. Which of these five commands did you already know before this module? Which was
   genuinely new?
2. You now have a real toolkit for Module 3's "where is the failure" question. What's still
   missing before you'd feel fully confident diagnosing a real production networking issue?

## Real Ops takeaway

**Five specific commands, each answering one specific question, beat one vague instinct that
"something's wrong with the network."** This is the exact toolkit real engineers reach for
first, in this order, when handed an unfamiliar connectivity problem. Module 5 puts all five
into one continuous diagnostic story; Module 6 formalizes the discipline around using them.

This module is complete. Continue to the next module.

## Instructor Notes

**Discussion questions for a live classroom:** question 2's honest answer is usually
"experience with real, varied failures" — a good moment to set expectations that fluency
compounds with practice, not from one module.

**Approximate timing:** 5-8 minutes live discussion; 5 minutes self-paced writing.
