What is the primary role of a Deployment in Kubernetes?

To manage a set of identical pods and ensure the desired number are running

To expose a set of pods to external traffic via a stable IP address

To store configuration data that can be mounted into pods

To provide a stable network identity for a pod that can be accessed by name

What is the primary function of a ReplicaSet in Kubernetes?

To provide load balancing for a set of pods

To store persistent data for stateful applications

To maintain a stable set of replica Pods running at any given time

To define the container image and command for a pod

Which type of disruption is a PodDisruptionBudget designed to protect against?

Voluntary disruptions, such as node maintenance

Involuntary disruptions, such as node failures

A containerized application takes up to 2 minutes to initialize before it can serve requests. The team has configured a liveness probe that starts checking immediately and fails during the initialization period, causing the container to be restarted repeatedly. They want to prevent this premature restarting while still detecting runtime failures after startup. What should they do?

Set the liveness probe's `periodSeconds` to 120.

Remove the liveness probe entirely.

Increase the liveness probe's `initialDelaySeconds` to 120.

Add a startup probe with a high `failureThreshold` and a `periodSeconds` that covers the startup window.

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 26 practice questions to prepare you well beyond it.
