Microsoft DevOps Engineer Expert AZ-400 Practice Question

Your organization operates a multi-tenant SaaS application on Azure Kubernetes Service. You must deploy a new microservice image with the following requirements:

  1. Start with a small internal tenant only.
  2. Evaluate live telemetry; automatically halt if latency or error rate exceeds predefined thresholds.
  3. Gradually expand the rollout to successive groups of tenants until all customers receive the update. Which deployment strategy best satisfies these requirements?

  • Blue-green deployment using a parallel AKS cluster and VIP swap

  • Single-step canary deployment that routes 10% of traffic to the new pod set

  • Ring-based deployment with quality gates between rings

  • A/B testing that directs half of users to each image version for comparison
