An administrator needs to configure a Kubernetes cluster in Azure to automatically adjust the number of nodes based on workload demands. Which feature should be used to achieve this?
Azure Traffic Manager
Azure Load Balancer
Azure Application Gateway
Kubernetes Cluster Autoscaler
The Kubernetes Cluster Autoscaler automatically adjusts the number of nodes in an Azure Kubernetes Service (AKS) cluster based on the resource demands of the workloads. It scales out by adding nodes when resource demands increase and scales in by removing nodes when demands decrease, ensuring efficient resource utilization and cost savings. Azure Load Balancer distributes network traffic across resources but does not handle scaling of cluster nodes. Azure Traffic Manager provides DNS-based traffic routing across regions, and Azure Application Gateway is a web traffic load balancer; neither manages node scaling in AKS.
