hard📝 Conceptual Q10 of 15

Kubernetes - Scheduling

ANode selectors allow pods to ignore node conditions

BTaints repel pods unless tolerated, allowing flexible exclusion

CTaints increase node resource limits dynamically

DNode selectors automatically remove pods from nodes

Step-by-Step Solution

Solution:

Step 1: Compare taints/tolerations with node selectors
Node selectors only select nodes by labels; taints repel pods unless they tolerate them.
Step 2: Understand flexibility of taints
Taints allow nodes to repel pods dynamically, giving admins more control over scheduling exclusions.
Final Answer:
Taints repel pods unless tolerated, allowing flexible exclusion -> Option B
Quick Check:
Taints provide flexible pod exclusion = D [OK]

Quick Trick: Taints repel pods; node selectors only filter nodes [OK]
