SOA-C03 - Networking and Content Delivery - Section 5.5
Troubleshoot VPC connectivity and interpret networking logs including VPC Flow Logs, Elastic Load Balancing access logs, AWS WAF logs and CloudFront logs.
Troubleshoot VPC connectivity by interpreting VPC Flow Logs and running VPC Reachability Analyzer to identify blocked paths through route tables, security groups, and network ACLs. Correlate Elastic Load Balancing access logs and CloudFront logs to isolate whether a connectivity or latency issue originates at the origin, the load balancer, or the edge.
