Prescreening Questions: Q: What strategies would you use to scale a web application handling millions of requests per second? A: Global CDN , Caching , DB Query Optimization / Indexing , Autoscaling Q: Difference between TCP & UDP A: TCP for HTTP/HTTP(S) applications. Reliable and Secure. Use cases: web, emails, file transfers UDP for is connectionless. Less / No reliability . Used for video streaming , gaming Q: What strategies do you use to improve Mean Time to Detect (MTTD) and Mean Time to Resolve (MTTR)? A: Enhance Monitoring & Observability Automate Alerts & Incident Detection (Use AI to integrate with monitoring tools to quickly diagnose the problem) Improve Runbooks & Incident Response (Clear and extensive runbooks for anyone on the team to be able to resolve issues quickly) Q: How would you handle DDoS attacks on a critical service? A: Not a short answer, can be very broad. Scale infrastructure temporarily to handle the surge. Identify attack vectors using monitoring tools and logs Enable DDoS protection services like AWS Shield , Azure DDoS Protection, or Google Cloud Armor. Rate limiting: Apply request throttling (AWS WAF, Cloudflare Rate Limiting). Implement CDN to absorb traffic surges Use geo-blocking temporarily to deny requests Q: What is the difference Authentication and Authorization ? A: Authn confirms who you are Authz determines what you can access once authenticated Q: Which k8s object is used to expose a pod or deployment to external traffic? A: Ingress or Kubernetes Ingress Q: Which k8s component is responsible for maintaining the desired state of the cluster? A: kube-controller-manager Q: What is the primary purpose of AWS KMS (Key Management Service)? A: AWS KMS is used to manage encryption keys for AWS services and applications . ensuring secured data encryption and decryption Q: What are Terraform state files, and why are they important?
