• Configure Extended Content Verification (ECV) monitors to perform application-aware health checks.
• Build and maintain GTM pools with defined failover and failback behavior.
• Design and manage LTM virtual servers (VIPs) and pools for local load balancing.
• Test and validate DNS-based automatic failover using real-time health signals.
• Tune monitoring thresholds and timers to prevent false failovers and traffic flapping.
• Support production incidents, change management activities, and disaster recovery exercises.
• Standardize configurations, documentation, and operational practices across environments.
