A city website Pod managed by a Deployment crashes and disappears from the node. What should restore the desired replica count?
Select an answer to reveal the explanation.
Short Explanation
Controllers are the cleanup crew: if a Deployment says three Pods and one dies, the ReplicaSet spins up another. DNS and Services route traffic—they do not babysit replica counts.
Full Explanation
Deployments own ReplicaSets, which continuously reconcile the number of Pods matching their selector to the desired replica count. When a Pod terminates unexpectedly, the ReplicaSet creates a new one. Services and DNS provide discovery and load balancing but do not replace failed workload instances.
