Microsoft Azure Administrator Associate AZ-104 Practice Question

Implementing a Horizontal Pod Autoscaler (HPA) allows the number of pod replicas to automatically scale in or out based on metrics such as CPU utilization. This ensures the application can handle varying workloads efficiently. Configuring the cluster autoscaler adjusts the number of nodes in the cluster, which affects the capacity for running pods but does not directly adjust the number of application instances. Using Virtual Nodes enables serverless Kubernetes pods but does not provide automatic scaling based on CPU demand. Manually increasing node count adds capacity but lacks automatic adjustment based on resource demands.
