# Destination reached!

Congratulations on completing this learning path! Job well done!

You’ve accomplished the following:

- Explained how spike-shaped load tests burst response and recovery in ways gradual ramps miss
- Designed a spike profile with short ramps, a burst hold, and a recovery observation window
- Ran a spike script locally and described what the aggregated summary shows (and what it hides across phases)
- Used a Grafana Cloud k6 timeline to correlate baseline, burst, and recovery for latency, errors, and throughput
- Documented per-phase metrics, recovery time, and a recovery category others can reuse
- Mapped results to investigations, SLO and alerting checks, and a spike retest cadence
- *(Optional)* Compared burst behavior across multiple endpoints with grouped, tagged requests in Grafana Cloud k6
- *(Optional)* Added bearer-style authentication from environment variables for protected routes
