   A developer needs to deploy a web application to AKS that must be accessible from the internet via a public IP address. The application consists of multiple replicas. What Kubernetes resources should the developer create?

   • AA Deployment and a Service of type ExternalName.
   • BA Pod and a Service of type NodePort.
   • CA Deployment and a Service of type ClusterIP.
   • DA Deployment for the application, a Service of type LoadBalancer, and an Ingress resource if host-based routing is needed.

   A company deploys a Container App that needs to scale based on both HTTP traffic and messages in a queue. They want to ensure that the app scales out when either metric increases. What should they do?

   • AConfigure multiple scale rules in the Container App, including HTTP and KEDA queue rules.
   • BUse only KEDA queue scaling and rely on it for all traffic.
   • CCreate two separate Container Apps, one for HTTP and one for queue processing.
   • DUse only HTTP scaling rules and process the queue within the same app.

   A company runs a Container App that processes messages from an Azure Service Bus topic. The processing is time-sensitive, and they need to ensure that messages are processed as soon as they arrive. They also want to minimize cost when there are no messages. What scaling configuration should they use?

   • AUse a cron trigger to process messages every few minutes.
   • BSet a high maxReplicas to handle peak load.
   • CConfigure KEDA with a Service Bus trigger, set minReplicas to 0, and use a short polling interval.
   • DSet minReplicas to 1 to avoid cold start latency.

   A team runs a background worker on Azure Container Apps that processes messages from an Azure Service Bus queue. The worker should scale out when the queue length grows and scale in when it drains. The team wants to avoid managing a separate scaling infrastructure. What should they configure?

   • ADeploy a Kubernetes HPA that monitors CPU usage of the worker and set the target average utilization to 70%.
   • BConfigure the worker to poll the Service Bus queue and use the Container Apps 'HTTP scaling' rule with a target of 10 concurrent requests.
   • CCreate a custom Azure Function that runs every minute and calls the Container Apps API to adjust the replica count based on queue length.
   • DDefine a KEDA scaler in the Container Apps scale rule configuration that references the Service Bus queue and set the minimum and maximum replicas.
