-The `az ssh arc` command allows users to remotely access a cluster VM that has been connected to Azure Arc. This method is a secure way to SSH into the cluster node directly from the command line. Once the cluster VM has been registered with Azure Arc, the `az ssh arc` command can be used to manage the machine remotely, making it a quick and efficient method for remote management.
