YES, there is a SIMILAR question on page 38 BUT it's for a container on WINDOWS OS!!! In this question with LINUX os, it should be virtual nodes. D To rapidly scale application workloads in an AKS cluster, you can use virtual nodes. With virtual nodes, you have quick provisioning of pods, and only pay per second for their execution time. You don't need to wait for Kubernetes cluster autoscaler to deploy VM compute nodes to run the additional pods.

It should be a horizontal pod scaler since its mentioned the containers auto-scaling here, in the case of node autoscaling we may use the cluster autoscaler.

I believe that's page 40, question 45. So yes, the answer is still AKS virtual nodes. The answer on page 40, question #45 is: "D: Virtual nodes with Virtual Kubelet ACI.

Correct answer should be A - Virtual Kuberlet "To rapidly scale application workloads in an AKS cluster, you can use virtual nodes. With virtual nodes, you have quick provisioning of pods, and only pay per second for their execution time. You don't need to wait for Kubernetes cluster autoscaler to deploy VM compute nodes to run the additional pods. Virtual nodes are only supported with Linux pods and nodes." "The virtual nodes add-on for AKS, is based on the open source project Virtual Kubelet" https://docs.microsoft.com/en-us/azure/aks/virtual-nodes

A is incorrect. You don't require Virtual Kubelet ACI for Linux. Its needed for manual mode for Windows. So correct option is D. AKS Virtual Nodes.

No it's not duplicate. The previous refers to Windows-based Pods. In that case Autoscaler was the correct answer. Now you can reduce the auto-scale process duration using Virtual Nodes
