You have an Azure subscription. You need to deploy an Azure Kubernetes Service (AKS) solution that will use Windows Server 2019 nodes. The solution must meet the following requirements: - Minimize the time it takes to provision compute resources during scale-out operations. - Support autoscaling of Windows Server containers. Which scaling option should you recommend?
Deployments can scale across AKS with no delay as cluster autoscaler deploys new nodes in your AKS cluster. Note: AKS clusters can scale in one of two ways: * The cluster autoscaler watches for pods that can't be scheduled on nodes because of resource constraints. The cluster then automatically increases the number of nodes. * The horizontal pod autoscaler uses the Metrics Server in a Kubernetes cluster to monitor the resource demand of pods. If an application needs more resources, the number of pods is automatically increased to meet the demand. Incorrect: Not D: If your application needs to rapidly scale, the horizontal pod autoscaler may schedule more pods than can be provided by the existing compute resources in the node pool. If configured, this scenario would then trigger the cluster autoscaler to deploy additional nodes in the node pool, but it may take a few minutes for those nodes to successfully provision and allow the Kubernetes scheduler to run pods on them.

Correct.
Cluster autoscaler help provision new nodes (compute ressources)
Cluster autoscaler works on top of horizontal pod autoscaler.
