An AKS cluster has a system node pool and a user node pool. You want to prevent user workloads from scheduling on system node pool nodes. What is the built-in mechanism AKS applies automatically to system node pools?

System pools are unschedulable by default via cordon
An OPA policy enforced by Azure Policy prevents scheduling
System node pools use a dedicated VLAN that rejects non-system pods
A nodeSelector label system=true blocks user pods automatically
A CriticalAddonsOnly=true:NoSchedule taint is applied

In AKS Automatic mode (GA 2024), which cluster management responsibility is fully removed from the operator compared to Standard mode?

Node pool configuration, OS upgrades, and Kubernetes version upgrades are fully managed by Azure
Pod security admission is disabled and replaced with built-in Azure Defender policies
RBAC configuration is automated via Entra ID group sync without operator input
Networking plugin selection is removed; Automatic always uses kubenet
The operator no longer needs to create namespaces; AKS generates them from workload annotations
