A service experiences variable traffic throughout the day. The team wants to automatically adjust the number of pod replicas based on CPU utilization, with a minimum of 2 and a maximum of 10 replicas. What should they configure?

A ClusterAutoscaler to add more nodes to the cluster

A HorizontalPodAutoscaler (HPA) targeting the Deployment with a CPU target and min/max replicas

A manual `kubectl scale` command run periodically

A VerticalPodAutoscaler (VPA) targeting the Deployment

What is the primary purpose of a Kubernetes Service?

To isolate resources within a cluster

To manage rolling updates of pods

To store sensitive data such as passwords

To provide a stable network endpoint for a set of pods

An application team needs to deploy a web frontend with three replicas and ensure that if a pod fails, Kubernetes automatically replaces it. They also want to be able to perform rolling updates in the future. Which Kubernetes resource should they create?

A ReplicaSet directly with replicas: 3

A single Pod with a label selector for the frontend

A Deployment that specifies replicas: 3 and a container image

A Service with a selector that matches the frontend pods

In Docker, what is the role of an image?

A network configuration for containers

A read-only template used to create containers

A running instance of a container

A storage volume for persistent data

Creating and Managing Containers in Kubernetes JN0-214 Practice Questions (Page 6)

Part of the Cloud Orchestration with Kubernetes domain, which makes up ~10% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–6 in this domain), expect 1–2 from this objective — we provide 40 practice questions to prepare you well beyond it.
