 | kubernetesImageBase             | no       | Specifies the base URL (everything preceding the actual image filename) of the kubernetes hyperkube image to use for cluster deployment, e.g., `k8s.gcr.io/`                                                                                                                                                                                                                                     |
-| loadBalancerSku                 | no       | Sku of Load Balancer and Public IP. Candidate values are: `basic` and `standard`. If not set, it will be default to basic.

+| loadBalancerSku                 | no       | Sku of Load Balancer and Public IP. Candidate values are: `basic` and `standard`. If not set, it will be default to basic. Requires Kubernetes 1.11 or newer. NOTE: VMs behind ILB standard SKU will not be able to access the internet without ELB configured with at least one frontend IP as described in the [standard loadbalancer outbound connectivity doc](https://docs.microsoft.com/en-us/azure/load-balancer/load-balancer-standard-overview#control-outbound-connectivity). For Kubernetes 1.11, We have created an external loadbalancer service in the kube-system namespace as a workaround to this issue. Starting k8s 1.12, instead of creating an ELB service, we will setup outbound rules in ARM template once the API is available.                                                                                                                                                                                                                                                                                                          |

 | networkPolicy                   | no       | Specifies the network policy enforcement tool for the cluster (currently Linux-only). Valid values are:<br>`"calico"` for Calico network policy.<br>`"cilium"` for cilium network policy (Lin), and `"azure"` (experimental) for Azure CNI-compliant network policy (note: Azure CNI-compliant network policy requires explicit `"networkPlugin": "azure"` configuration as well).<br>See [network policy examples](../examples/networkpolicy) for more information.                                                                                                                                  |
