Choose two. After a networking outage that correlated with routing changes and a spike in denied flows, which two data sources should you examine first to reconstruct a timeline and identify routing and policy causes?

VPC Flow Logs provide crucial details on network traffic, including accepted or denied connections and byte counts, directly indicating if traffic was dropped and how much. VPC firewall rule logs in Cloud Logging show which firewall rules were hit and if they denied traffic, directly revealing policy-based blocks. Together, these logs offer a comprehensive view of traffic flow and policy enforcement during the outage. Packet Mirroring is too resource-intensive and generates excessive data for initial troubleshooting of a broad outage. Cloud Monitoring uptime checks only confirm service availability, not the underlying network or policy reasons for traffic disruption.
