Kubernetes - Scheduling

If a node has a taint key=value:NoExecute and a pod has no tolerations, what will happen to the pod after it is scheduled on that node?

AThe pod will be scheduled but evicted after a grace period

BThe pod will remain running indefinitely

CThe pod will be immediately evicted from the node

DThe pod will ignore the taint and stay

Step-by-Step Solution

Solution:

Step 1: Understand NoExecute taint effect
NoExecute taint evicts pods that do not tolerate it immediately or after a grace period.
Step 2: Consider pod tolerations
The pod has no tolerations, so it cannot stay on the node with NoExecute taint.
Final Answer:
The pod will be scheduled but evicted after a grace period -> Option A
Quick Check:
No toleration for NoExecute taint causes eviction = A [OK]

Quick Trick: NoExecute taint evicts pods without tolerations immediately [OK]
