Designing Azure Infrastructure Solutions — Question 19

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?

Answer options

Correct answer: D

Explanation

The cluster autoscaler is the correct answer because it automatically adjusts the size of the Kubernetes cluster based on demand, which minimizes provisioning time during scale-out operations. The horizontal pod autoscaler adjusts the number of pods rather than the nodes, while Virtual nodes are used for on-demand pods and do not directly address the scaling of Windows Server nodes. Kubernetes version 1.20.2 or newer is a requirement for compatibility but does not influence the scaling strategy itself.
