The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'.

You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_k8s extension_extension types_list versions'.The syntax is: az k8s-extension extension-types list-versions --cluster-name
                                               --cluster-type {appliances, connectedclusters, managedclusters}
                                               --extension-type
                                               --resource-group
                                               [--major-version]
                                               [--release-train]
                                               [--show-latest {false, true}]. The parameter '--cluster-name -c' is required. It is used to name of the kubernetes cluster.. The parameter '--cluster-type -t' is required. It is used to specify arc clusters or aks managed clusters or arc appliances.. The parameter '--extension-type' is required. It is used to name of the extension type.. The parameter '--resource-group -g' is required. It is used to name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--major-version' is optional. filter results by only the major version of an extension type. for example if 1 is specified, all versions with major version 1 (1.1, 1.1.2) will be shown. the default value is none.. The parameter '--release-train' is optional. specify the release train for the extension type.. The parameter '--show-latest' is optional. filter results by only the latest version. for example, if this flag is used the latest version of the extensiontype will be shown..
