Observability Concepts

Q1. What is an error budget in SRE practice?

Answer options for question 1
  • Incorrect. Error budgets are reliability accounting, not financial budgets.

  • Incorrect. That describes on-call burden metrics, not error budgets.

  • Incorrect. Alert volume is a symptom of noise, not an error budget concept.

  • Correct. The error budget equals 1 - SLO applied to the measured window — it quantifies how much unreliability is acceptable before halting risky changes.
