# Guided Exercise: Which Command Answers This Question?

This is a paper exercise — commit to an answer before checking it in the Lab.

## Your task

For each question, name the ONE command you'd reach for first:

1. "Does this machine have a working IP address at all?"
2. "Is anything listening on port 8080 right now?"
3. "Does `payments.internal` resolve to an address?"
4. "Is the web server actually returning a valid response, not just accepting connections?"
5. "Where does traffic to an address outside my local subnet actually go?"

## A worked shape to check yourself against

1. `ip -4 addr show`
2. `ss -lnt | grep 8080`
3. `getent hosts payments.internal`
4. `curl -sf http://.../ -o /dev/null -w '%{http_code}'`
5. `ip route`

## Instructor Notes

**Facilitation:** Have students justify WHY their chosen command answers the specific question
asked, not just that it's "a networking command" — the goal is precision, not familiarity.

**Approximate timing:** 8-10 minutes live discussion; 5 minutes self-paced.
