What is the primary purpose of a ResourceQuota in a Kubernetes namespace?

To set default resource requests for individual containers.

To define the maximum number of replicas for a Deployment.

To constrain the total amount of resources (e.g., CPU, memory) that can be consumed by all objects in the namespace.

To restrict which nodes Pods can be scheduled on.

A cluster has a mix of critical and non-critical workloads. Critical Pods have a PriorityClass with a high priority value, and non-critical Pods have a lower priority. A critical Pod cannot be scheduled because all nodes are at capacity. What will the scheduler do?

It will leave the critical Pod Pending and wait for resources to become available.

It will reject the critical Pod with an error.

It will schedule the critical Pod on a node that has insufficient resources, ignoring the requests.

It will preempt (evict) lower-priority Pods to free resources for the critical Pod.

What is the role of Pod priority in Kubernetes scheduling?

It controls the order in which containers start within a Pod.

It determines the order in which pending Pods are considered for scheduling, and higher-priority Pods can preempt lower-priority Pods.

It defines which nodes the Pod can be scheduled on.

It sets the CPU and memory limits for the Pod.

What is the purpose of a taint on a Kubernetes node?

To automatically add resource limits to Pods on that node.

To mark a node so that only Pods with matching tolerations can be scheduled on it.

To label a node for use with nodeSelector.

To increase the priority of Pods scheduled on that node.

What is the primary role of admission controllers in the Kubernetes API request lifecycle?

They schedule Pods onto nodes based on resource availability and constraints.

They intercept requests after authentication and authorization, and can validate or mutate them before the object is persisted.

They authenticate users and determine whether a request is authorized.

They manage the lifecycle of running containers by starting and stopping them.

Configure Pod Admission and Scheduling (limits, Node Affinity, Etc.) CKA Practice Questions (Page 3)

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.
