Pods Deployments· Scenario-based

Q1.Your Deployment has 5 replicas. You roll out a new image version. 3 pods crash immediately (CrashLoopBackOff). What Kubernetes feature prevents all 5 pods from being replaced simultaneously?

PodDisruptionBudget — prevents any rolling update from occurring

RollingUpdate strategy with maxUnavailable and maxSurge — controls how many pods can be down or over-provisioned during the update

Kubernetes automatically pauses rollouts on CrashLoopBackOff

Liveness probes abort the rollout and roll back automatically
