Lab Guide: how labs work, what to submit, how to pass

Lifecycle you’ll follow in every lab

Read the lab guide → clarify scope, risk, success criteria.

Pre-change snapshot → backup config/screens; note current state.

Implement → GUI/CLI with small, reversible steps.

Validate → functional tests + security checks; collect logs/metrics.

Document → what changed, why, evidence, and a backout plan.

Grading rubric (typical)

Correctness (60%)

Validation evidence (20%)

Safety/backout (20%)
