   • AVerify the Kubernetes Service and Endpoints for the database are correctly defined.
   • BCheck the microservice's CPU and memory usage.
   • CVerify the database container image is up to date.
   • DRestart the microservice pods.

   A developer needs to deploy a stateful application to AKS that requires stable network identities and persistent storage. The application is a database that should not have multiple instances writing to the same volume. What Kubernetes resource should the developer use?

   • AA DaemonSet that runs one pod on each node with a hostPath volume.
   • BA StatefulSet with a PersistentVolumeClaim template and a headless Service.
   • CA Deployment with a single replica and a PersistentVolumeClaim.
   • DA Job that runs the database once and exits.

   A team runs a background job processor on Azure Container Apps. The job processes messages from an Azure Service Bus queue. The team wants the number of instances to scale automatically based on the queue length, and they want to avoid polling costs when the queue is empty. What should they configure?

   • AEnable HTTP scaling rules based on incoming request rate.
   • BEnable KEDA scaling with a Service Bus trigger and set the minimum replicas to zero.
   • CSet the minimum replicas to one and use a cron trigger to process messages periodically.
   • DUse the built-in Azure Container Apps autoscaler with CPU and memory thresholds.

   A developer needs to deploy a microservice to an existing AKS cluster. The deployment must define the container image, resource requests/limits, and a liveness probe. The team uses GitOps practices and wants the configuration to be declarative and version-controlled. What should the developer do?

   • ARun docker run with the image name and resource flags on the AKS node VM.
   • BUse the az aks create command with the --node-count parameter to deploy the microservice directly.
   • CUse kubectl run to create a single pod with the image and resource flags.
   • DCreate a Kubernetes Deployment manifest YAML file and apply it with kubectl apply.
