Master interview answers on HA/DR strategies including multi-region failover, RTO/RPO targets, and resilience engineering.
Practice This QuestionEstablish clear Recovery Time Objective (RTO) and Recovery Point Objective (RPO).
Deploy multi-AZ or multi-region setups with automated load balancing.
Utilize active-active or active-passive databases with automated failover.
Conduct routine game-day chaos engineering and automated backup restorations.
“High availability starts with eliminating single points of failure. I design core services for multi-AZ or multi-region active-active deployments using global load balancers (like AWS Route53 or Cloudflare) with automated health checks. For database DR, I match architecture to RTO and RPO requirements—using cross-region read replicas with automated failover scripts for sub-minute RTO. Additionally, I enforce stateless app nodes, graceful degradation via circuit breakers (e.g., resilience4j), and validate DR readiness using scheduled Game Day drills and chaos testing.”
“I ensure high availability by deploying applications across multiple availability zones behind auto-scaling groups and load balancers. For disaster recovery, we maintain automated daily database backups with point-in-time recovery enabled and test automated restoration procedures quarterly to guarantee low RTO and RPO.”
“I help maintain high availability by making sure code runs statelessly across multiple server instances so if one instance crashes, traffic routes to healthy instances without user interruption.”
