Kubernetes and Cloud Native Associate (KCNA) — Question 91

Which of these events will cause the kube-scheduler to assign a Pod to a node?

Answer options

• A. When the Pod crashes because of an error.
• B. When a new node is added to the Kubernetes cluster.
• C. When the CPU load on the node becomes too high.
• D. When a new Pod is created and has no assigned node.

Correct answer: D

Explanation

The correct answer is D because the kube-scheduler's primary responsibility is to assign Pods to nodes based on resource availability. Options A, B, and C do not trigger scheduling; A refers to a Pod that is already running, B pertains to cluster expansion which does not directly assign Pods, and C indicates a resource issue rather than a scheduling action.
