CKA KUBERNETES TEST QUESTIONS AND
CORRECT ANSWERS.
According to Kubernetes, What is Kubernetes
"an open-source system for automating deployment, scaling, and management of containerized
applications".
What is a Kubelet
The primary "node agent" that runs on each node. It can register the node with the apiserver
using one of: the hostname; a flag to override the hostname; or specific logic for a cloud
provider.
What is a Kubeproxy
one of the main components of the Kubernetes control plane, the brains of your cluster.
What is a Feature Gate
set of key=value pairs that describe Kubernetes features.
In Kubernetes what is Affinity
a set of rules that give hints to the scheduler about where to place pods.
In Kubernetes what is Annotation
A key-value pair that is used to attach arbitrary non-identifying metadata to objects.
What is API Group
A set of related paths in Kubernetes API.
What is Kube-API Server
The API server is a component of the Kubernetes control plane that exposes the Kubernetes API.
The API server is the front end for the Kubernetes control plane.
What is Applications
The layer where various containerized applications run.
, What is cgroup
A group of Linux processes with optional resource isolation, accounting and limits.
What is a Cluster
A set of worker machines, called nodes, that run containerized applications. Every cluster has at
least one worker node.
What is a Container
A lightweight and portable executable image that contains software and all of its dependencies.
What is Container Environment Variables
Container environment variables are name=value pairs that provide useful information into
containers running in a pod
What is Container Runtime
The container runtime is the software that is responsible for running containers
What is Container Runtime Interface
The container runtime interface (CRI) is an API for container runtimes to integrate with kubelet
on a node
What is Control Plane
The container orchestration layer that exposes the API and interfaces to define, deploy, and
manage the lifecycle of containers.
What is a Controller
In Kubernetes, controllers are control loops that watch the state of your cluster, then make or
request changes where needed. Each controller tries to move the current cluster state closer to the
desired state.
What is CustomResourceDefinition
Custom code that defines a resource to add to your Kubernetes API server without building a
complete custom server
