Explanation

Network Intelligence Center Connectivity Tests perform a static simulation of the network data path between two endpoints. It analyzes the applicable VPC firewall rules, routes, and network configuration to determine exactly where and why traffic is being dropped - distinguishing between a firewall rule block and a routing failure. This gives you the definitive answer without needing to generate live traffic. VPC Flow Logs (option C) only show metadata about flows that were actually processed by the network; they do not explain routing decisions or definitively identify firewall drops. Network Topology (option B) visualizes traffic volumes but does not diagnose specific packet-level drops.
