Not true. The CLI was already installed, the question is about the next step after the CLI has been installed.

You are confusing the az cli and the kubernetes cli. If you haven't installed kubernetes cli, how can you run kubectl?

its only true if you are running it from the Azure cloud shell, but the question states you running it from an Azure joined devices, that means that you running it locally - install kubectl locally using the az aks install-cli command: To manage a Kubernetes cluster, use the Kubernetes command-line client, kubectl. kubectl is already installed if you use Azure Cloud Shell.

C is the right answer indeed. Just try it yourself, it's a simple 5 - 10 mins task. First, install Azure CLI on your local machine / laptop. Second, using Azure CLI, connect to your Azure subscription. Third, try to use option A or D and you will get an error - 'kubectl' is not recognized as an internal or external command, operable program or batch file. Now try az aks install-cli and then run this command: az aks get-credentials --resource-group "your resource group name where you deployed aks cluster" --name "your aks cluster name" After that you try option A and Option D and it will work. So, to summarize you need aks cli before running any kubectl command on your local machine. That's why option C is the correct answer. Trying option A or D without aks cli won't work on your local machine but will work on Azure cloud shell because cloud shell has aks cli already installed.
