Azure Interview Questions
34 questions
Azure interview questions covering identity and networking (managed identities, RBAC, Key Vault, private connectivity), compute (App Service, Azure Functions), storage (Blob Storage access, security, and recovery), and AKS — scenario-driven, matching the same depth as this site's AWS and GCP coverage.

A new LoadBalancer-type Service in AKS has been stuck in 'Pending' with no external IP for twenty minutes. How do you actually diagnose this in Azure specifically?

During a live incident, how would you distinguish a genuinely slow autoscaler scale-up from one that's actually stuck and won't complete on its own?
