Microsoft Azure Solutions Architect Expert AZ-305 Practice Question

Your company operates 20 containerized microservices running on multiple Azure Kubernetes Service (AKS) clusters and Azure App Service instances across three regions. Each microservice relies on dozens of environment-specific settings and several feature flags that must be toggled gradually during rollouts without redeploying the services. You need a centrally managed solution that provides RBAC-controlled access, auditing of changes, automatic client-side caching with event-based refresh, and secure storage of connection strings in an HSM-backed store. Which design should you recommend?

  • Persist all settings and feature flags in Azure Table Storage, have microservices poll the table periodically, and encrypt secrets stored in the same table with client-side encryption.

  • Store configuration values and feature flags in Azure App Configuration and reference secrets stored in Azure Key Vault; use Azure App Configuration provider libraries for caching and sentinel-based refresh.

  • Maintain environment-specific values in Kubernetes ConfigMaps synchronized with Argo CD for each cluster, and keep secrets in Kubernetes Secrets.

  • Store all configuration data, including feature flags, in Azure Key Vault; mount secrets to the AKS pods with the CSI driver and implement custom polling for App Service.
