Answer
Taints prevent scheduling unless Pods have tolerations.
Quick Answer
A taint on a node repels Pods that don't explicitly tolerate it. Use it to reserve nodes for specific workloads — taint GPU nodes so only GPU-requesting Pods land there, taint production nodes so dev Pods can't accidentally run on them. Tolerations on Pods say "I'm okay with this taint" — they can still land on tainted nodes.
