A package of pre-configured Kubernetes YAML templates

A collection of versioned Custom Resource Definitions

A binary executable used to manage container runtimes

A configuration file for defining RBAC user permissions

What is the primary difference between Helm and kubectl?

Helm manages app lifecycles; kubectl manages atomic resources

kubectl is used for cloud APIs while Helm is for local clusters

Helm is purely imperative while kubectl is strictly declarative

kubectl requires a client-side database to track state

To provide default parameters for the template engine

To store the application source code and build scripts

To define the sequence in which Kubernetes pods are started

To list the external dependencies and required Helm repos

What is a Helm "Release"?

A specific instance of a Chart running in a cluster

A specific version of the Helm binary (e.g., v3.12.0)

The process of pushing a packaged Chart to a repository

A snapshot of the etcd database used for cluster recovery

Which command is used to install a new chart?

helm install [release-name] [chart]

helm deploy [release-name] [chart]

kubectl apply -f [chart-directory]

What does "helm upgrade --install" do?

It updates an existing release or installs it if missing

It purges all existing revisions before performing a clean install

It verifies the Helm client version against the cluster API

It synchronizes the local chart cache with the remote repository

What is a Helm "Revision"?

An incremental version of a Release used for rollbacks

A unique hash representing a single Git commit

A minor version change in the Chart.yaml file

A pull request submitted to the official Helm repo

How do you roll back a release to a previous version?

helm rollback [release] [revision]

What is the purpose of the "Chart.yaml" file?

To store metadata like name, version, and description

To define the environment variables for the pod

To specify the persistent volume mount paths

To configure the Kubernetes API endpoint

What is a "Helm Repository"?

A hosted server containing packaged charts and an index

A Git repository containing the source code

A local database storing the history of all releases

A container registry used for storing Docker images

What does "helm lint" do?

It identifies potential issues and best-practice violations

It removes unused Kubernetes resources from the cluster

It compresses the Chart directory into a .tgz archive

It automatically formats the YAML indentations

What is a "Dry Run" in Helm?

Rendering templates and verifying them without deploying

Running the application in a restricted network mode

A performance test to measure resource consumption

Checking if the required Docker images exist in the registry

What is a "Library Chart"?

A Chart used to share common logic between other Charts

A collection of documentation and README files

A public repository of certified Kubernetes apps

A specialized Chart for managing database schemas

How do you override a value from the command line?

helm install --override key=value

What is a "Chart Dependency"?

An external Chart that your Chart relies upon

A specific version of Kubernetes required by the Chart

A mandatory label required by the company policy

A link between a pod and its persistent storage volume

What does the "helm list" command do?

Displays all Helm releases deployed in a namespace

Displays all files currently stored in a Helm Repo

Displays all available Kubernetes namespaces

Displays the history of changes for a specific Chart

What is the "Helper" file (_helpers.tpl) used for?

To define reusable partials and template logic

To store secret passwords and TLS certificates

To configure the local shell environment for Helm

To provide a checklist for manual deployment steps

What is "Helm Chart Version" vs "App Version"?

Chart version tracks the package; App version tracks the software

The Chart version tracks the API; App version tracks the OS

They are redundant fields and should always be identical

App version is only required for Docker-based deployments

What is "Helm Tiller"?

The server-side component removed in Helm 3

A client-side plugin for managing multi-cluster auth

A specialized node pool for running heavy Helm jobs

The default storage backend for Helm release state

What is the "helm pull" command?

Downloads a Chart from a repository for local inspection

Synchronizes the local Git branch with a remote repo

Updates the local metadata for all registered repositories

Fetches the latest logs from a running Release pod

What is a "Chart Hook"?

A mechanism to trigger actions during a Release lifecycle

A security breach within the template rendering engine

A link between two different Helm repositories

A way to pause a Release until an external health check passes

What does "helm template" command do?

Renders the Chart templates into YAML locally

Creates a new directory structure for Chart development

Validates that the Chart follows the official security lint

Uploads the rendered YAML to a public code repository

What is the purpose of the "index.yaml" file in a repo?

To list all available Charts and their metadata in a repo

To provide a landing page for human users in a browser

To track the sequence of all historical cluster deployments

To define the default networking rules for the repository server

How do you delete a Helm release?

kubectl delete release [release-name]

What are "Global Values"?

Values accessible to both a parent Chart and its sub-charts

Configuration settings that apply to every cluster in the world

Standard constants defined by the Kubernetes API

Settings that can only be modified by a cluster administrator

What is the "NOTES.txt" file used for?

To provide post-installation instructions to the user

To record the technical changes in a new release (Changelog)

To list the internal variables used for debugging templates

To store the license agreement for the software

What is "Helm Chart Testing" (helm test)?

Executing specific pods to verify a running release

A static analysis of the Go template syntax

Load-testing the cluster to find the maximum pod capacity

Checking the code for security vulnerabilities using a scanner
