AZ-300 Azure App Services & Containers 2 — Questions and Answers
Question 1: Which Azure Kubernetes Service networking mode provides each pod with an IP address directly from the VNet subnet?
- kubenet
- Azure CNI (Correct answer)
- Bridge networking
- Host networking
Correct answer: Azure CNI
Azure CNI (Container Network Interface) allocates VNet IP addresses to each pod, enabling direct VNet-native connectivity and NSG/route table support.
Question 2: What is the purpose of AKS 'node pools' with different VM sizes?
- Isolate production from development subscriptions
- Allow different workloads to run on hardware optimized for their requirements (Correct answer)
- Separate cluster control plane from workers
- Enable multi-region deployment
Correct 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.
Question 3: Which Azure service allows you to run event-driven containerized microservices without managing Kubernetes infrastructure?
- Azure Kubernetes Service
- Azure Container Instances
- Azure Container Apps (Correct answer)
- Azure Functions
Correct 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.
Question 4: What is the benefit of using Azure App Service 'Hybrid Connections'?
- Load balance traffic across regions
- Allow web apps to securely access on-premises resources without VPN or inbound firewall changes (Correct answer)
- Enable WebSocket support
- Provide custom domain SSL
Correct 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.
Question 5: Which AKS feature automatically right-sizes node VM counts based on pending pod scheduling requirements?
- Horizontal Pod Autoscaler
- Vertical Pod Autoscaler
- Cluster Autoscaler (Correct answer)
- Node Pool Scaling
Correct 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).
Question 6: Which App Service authentication feature allows you to integrate Azure AD login into your web app without writing auth code?
- App Service Managed Identity
- Easy Auth (App Service Authentication) (Correct answer)
- CORS configuration
- Custom Token Middleware
Correct answer: Easy Auth (App Service Authentication)
App Service Authentication (Easy Auth) adds authentication middleware in front of your app, handling Azure AD token validation without modifying app code.
