What is the purpose of AKS 'node pools' with different VM sizes?

Answer: Allow different workloads to run on hardware optimized for their requirements

AKS node pools let you run different VM types (GPU, memory-optimized) in the same cluster, dedicating the right hardware to each workload type.

Which Azure service allows you to run event-driven containerized microservices without managing Kubernetes infrastructure?

Answer: Azure Container Apps

Azure Container Apps is a serverless container platform built on Kubernetes and KEDA that lets you run microservices with auto-scaling to zero.

What is the benefit of using Azure App Service 'Hybrid Connections'?

Answer: Allow web apps to securely access on-premises resources without VPN or inbound firewall changes

Hybrid Connections allow App Service apps to reach on-premises TCP resources by establishing an outbound relay connection via Azure Service Bus, requiring no inbound firewall changes.

Which AKS feature automatically right-sizes node VM counts based on pending pod scheduling requirements?

Answer: Cluster Autoscaler

The Cluster Autoscaler adds or removes nodes based on whether pods cannot be scheduled (scale-out) or nodes are underutilized (scale-in).

Which App Service authentication feature allows you to integrate Azure AD login into your web app without writing auth code?
