What happens when you set spec.nodeName in a Pod definition?

The Pod is rejected because nodeName is not a valid field.

The Pod is scheduled by the scheduler but with a preference for that node.

The Pod is assigned directly to the specified node, bypassing the scheduler.

The Pod is scheduled on any node, but the nodeName is used for logging.

An application has multiple replicas of a stateful workload. To ensure high availability, the replicas should be spread across different nodes. The Pods are labeled `app=stateful`. Which podAntiAffinity rule should be used?

podAntiAffinity with preferredDuringSchedulingIgnoredDuringExecution, labelSelector matchLabels app=stateful, topologyKey kubernetes.io/hostname

podAntiAffinity with requiredDuringSchedulingIgnoredDuringExecution, labelSelector matchLabels app=stateful, topologyKey kubernetes.io/hostname

nodeAffinity with requiredDuringSchedulingIgnoredDuringExecution, labelSelector matchLabels app=stateful, topologyKey kubernetes.io/hostname

podAffinity with requiredDuringSchedulingIgnoredDuringExecution, labelSelector matchLabels app=stateful, topologyKey kubernetes.io/hostname

Which of the following is a limitation of nodeSelector compared to node affinity?

nodeSelector only supports exact label matching and cannot express soft preferences or complex expressions.

nodeSelector cannot be used with namespaces.

nodeSelector only works with the default scheduler.

nodeSelector can only be used with nodes that have no taints.

What is the purpose of a LimitRange object in a Kubernetes namespace?

To restrict which nodes Pods can be scheduled on in the namespace.

To limit the total amount of resources consumed by all Pods in the namespace.

To define the maximum number of Pods that can run in the namespace.

To set default and maximum resource requests/limits for Pods and containers in that namespace.

Which of the following can a ResourceQuota limit in a namespace?

The total CPU and memory requests across all Pods.

The number of containers in a single Pod.

The number of namespaces in the cluster.

The number of nodes in the cluster.

Configure Pod Admission and Scheduling (limits, Node Affinity, Etc.) CKA Practice Questions (Page 4)

Part of the Workloads and Scheduling domain, which accounts for 15% of the CKA exam. Linux Foundation does not publish an official question count, but from its 120-minute exam (~50–80 total, ~8–12 in this domain), expect 2–2 from this objective — we provide 29 practice questions to prepare you well beyond it.
