Today: resilience (22%) and monitoring (14%), together 36% of the exam. Again, split in the blueprint but woven in practice. Resilience without observability is blind — you rebuild the same failure. Observability without resilience is watching burndown without circuit breakers. Today, link them as "observability detects failure, resilience contains blast radius, feedback loop prevents recurrence."
Resilience starts with business language, not engineering.
