An application is deployed with 3 replicas. A PodDisruptionBudget has minAvailable: 2. What is the maximum number of pods that can be voluntarily disrupted at once?

1. ✓ A 1 (correct answer)
2. B 2
3. C 3
4. D 0

Shortcut: With minAvailable: 2 and 3 replicas, at most 1 pod can be disrupted at a time (3 - 2 = 1). Voluntary disruptions (upgrades, drains) are blocked if they would violate this.
